Skeletal System

Integumentary System
Through out the body there are 11 major organ systems that work together to perform a specific function to maintain the body but still having similarities. The Integumentary System consists of skin, nails, hair, and exocrine glands being the largest organ in the body. This system is the first line of defense against viruses, bacteria, and is a barrier to protect the body form UV light, chemicals,disease, and physical damage. The Integument has 3 layers; the Epidermis, Dermis, and the Hypodermis. The Epidermis is the outer layer of the skin that contains keratin. Keratin is a protein that helps strengthen the skin and hair. This gives the skin the ability of flexibility.

Skeletal System
The Skeletal System is made up of 206 bones in an adult. The functions it performs are; support, movement, protection. The physiology functions are blood cell formation and storage of calcium. There's two basic types of bones: compact bone and spongy bone. This system is the bones and the tissues such as cartilage,tendons, and ligaments that connect to them. The Skeletal System supports the body because without bones our bodies would just collapse on the floor. Also it protects the internal organs, for example the skull protects the brain and the ribs protect the heart and lungs. Last but not least it helps with movement, bones provide the structure for muscles to attach so that our bodies are able to move.

The Integumentary and Skeletal System
A few ways the Integumentary and Skeletal systems are physiologically related are by how both systems have a function to protect. The skin protects the internal organs such as the bones. The Skeletal System is dependent of the Integumentary System for the calcium that keeps are bones strong and healthy. Through sunlight, a vitamin D precursor is produced in the dermal capillary blood. It regulates the carrier system that absorbs calcium from ingested foods into blood. Since calcium is needed for several things in the body and bones store it, and if bones don't get enough, they become weak and soft, which causes problems with being able to support the rest of the body. That is why without absorbing vitamin D through the skin the bones wouldn't be able to absorb the amount of calcium it needs.

Egil's Bone

Egil was a viking born in Iceland in the early 10th century. He was a very brave and heroic figure to his people, but he had a unique appearance. Egil had something called Paget Disease, it is a bone disorder where some bones grow abnormally; changing their size and shape. Paget Disease is commonly found more in men from 55 to 60 years of age. It causes pain in the bones and nearby joints. This tends to affect the skull, spine, pelvis,and long bones. This disease is does not spread form bone to bone but rather stays within the bone or bones being affect throughout a lifetime.

 The physiological changes that goes on in your body with this disease are quite a few; listing some would be heart failure, hearing or vision loss, pinched nerves, and joint damage. When the bones are enlarging and misshaped its causing damages to other organs, for example if Paget Disease is affecting the skull, it will soon begin to grow in a mishaped way an eventually sufficate the brain. It does this because this disorder causes the formation of the bone to change and they start to fuse together in a way. If this is happening to the skull, eventually the brain will have no space to be in along with the eyes and if all the air way passages begin to close up, you die of lack of oxygen. If a different bone is being affected like the pelvic or the bones in your legs it can put a lot of stress on nearby joints causing the cartilage to breakdown which later on will cause osteoarthritis. Heart failure is a problem because the heart will have to work harder to pump blood to the affected areas. Nerve pinchings occur when Pagets Disease affects the spine because of the excessive growth in the spinal column. 

The anatomical changes that goes on in your body with this disease would have to be your bone structure. Like how I explained earlier, this disease makes your bones enlarge and fuse together causing an abnormal shape. When the bone resorption begins to outpace bone formation meaning the old bone breaks down faster than the new bone is built, your body will try to compensate by speeding up bone formation, this is why it appears to be odd shaped and large. When this happens to the leg bones, they become weak and can bend causing the legs to be bowlegged. This can put pressure on your knee cap and joints around there causing wear and tear and possibly fractures and making it hard to walk. When Pagets Disease affects the spine, you start to feel nerve pinching, numbness, and tingling, also it can stoop forward your posture.

3 Question Blog #5

What tasks have you completed recently?

Something I have completed recently was I started to work out again. I haven't really had time to fit it in my schedule because of school and practice . But our coach recently told us that he was going to put conditioning back into our practices since we're getting ready for competition season. So with that being done I won't have to struggle and try to fit working out in my schedule .

What have you learned recently ?

Recently in Pre Calc I've been learning about the Unit Circle and the radians according to the unit circle. Sometimes it gets kind of hard but once you go over it a couple of times it eventually starts to just come easy and fast to you. In Anatomy we've been learning about the Skeleton System and its different form and functions.   

What do you plan on doing next ?

Next I plan on keeping up in Pre Calc and Anatomy. Also I need to step up my game in cheer and well I'm actually happy that we're going to be conditioning after practice even if its the last 30 minutes of practice. Also
I'm very nervous and excited for this up coming week because its Mayfield vs Cruces week. And we just found out that we are performing a home pom dance routine at our pep assembly, and its starting to kind of stress me out because the assembly is coming up fast.

 

                             

The Integumentary System

The Integumentary System

The Integumentary System is the largest organ in the body consisting of skin, nails, hair, and exocrine glands. The skin forms a barrier to protect the body from UV light, chemicals, disease, and physical damage. The Integumentary System is the first line of defense against bacteria, viruses, and other microbes. The skin is a sensory organ which has receptors that detect heat and cold, touch, pressure and pain. The Integument has three layers; the Epidermis, Dermis, And the Hypodermis. The Epidermis is the outermost layer of the skin composed of stratified squamous cells. The Epidermis contains 5 layers; stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum starting from the bottom up, the stratum basale is made up of keratinocytes and melanocytes. The keratinocytes are what make protein to give off to the cells and make the cells hard. Melanocytes are what make melanin and protect the skin from overexposure of sunlight. The stratum spinosum is the layer that the cells look kind of spiny, its main function is to protect against foreign materials and to produce and retain lipids that prevent moisture loss from the skin. The stratum granulosum is the layer where keratin proteins and water-proofing lipids are being produced and organized. The stratum lucidum is the layer of dead skin cells it's function is to help the body handle friction, that is why it is mostly located where you have thick skin such as the soles of your feet and the palms of your hand. Last but not least the stratum corneum is made up of dead layers that keep bacteria out and keeps in body fluid.

Layers of the skin.

The Integumentary System helps maintain homeostasis because it helps assist in the regulation of body temperature, water balance, protection, sensory reception, biochemical synthesis, and absorption. An example of homeostasis would be when you get cold, your body has to warm itself up to the regular temperature the body is used to being at through and vasoconstriction. When your body is too cold it uses vasoconstriction to keep your body warm and from freezing, it contracts your muscles to produce heat for your body. The muscle arrector pili is what causes goose bumps.When these muscles contract, they make the hair follicles to stand on their ends thus leading to goose bumps. This process is important for insulation of the body and heat retention.

3 Question Blog #4

What tasks have you completed recently ?

• This whole week I've been really proud of myself because I finally caught up in math. Also we started a new chapter and its so far going pretty good, I actually understand what we're doing. Along with catching up in math comes falling behind in Anatomy.. so I'm not happy over that at all. Not to mention trying to balance practice, games, fundraisers, and whatever else comes across my schedule. 

What have you learned recently ? 

• I learned that it's not easy to play catch up in anything, especially in my classes. But hopefully I wont have to for long !! In my Medical Terminology class we're learning about the Cardiovascular and Respiratory system, and wow there's so much to know about them. For example, the differences in what a vein, capillary, and an artery are and which one carries non-oxygenated blood and which one carries oxygenated blood. I learned what the anatomy and physiology of the heart is and of respiration. 

What are you planning on doing next ? 

• There's lots of things I plan on doing next, like catching up in Anatomy is my first priority !! After that I can try to balance out everything else in life and hopefully keep it balanced. I also want to start taking tutoring classes for the A.C.T. I'm actually very nervous for that even though its not til a long ways from now. 

3 Questions Blog # 3

What tasks have you completed recently ?

• Well to start off, this week wasn't as crazy busy as last week; which is great for me. I cheered at a football game on Friday in Albuquerque. Hmm what to say about that, let's start off with the bus ride that seemed like it took forever. Albuquerque didn't quite have your typical nice weather like Las Cruces usually did during night games here at the field of dreams. It was freezing during the game. Not to mention we lost to Volcano Vista.. but hey we kept our heads up and well it happens. That night I didn't get home and go to bed 'til around 2 in the morning, talk about a long day. Anyways, that's pretty much what task i completed recently worth sharing.  

What have I learned recently ?

• Something that I would like to share is in my Anatomy class we've been talking about stem cell research. At first I had no clue what it was or what it meant, later on in the week I learned a lot about it. I now know that in a way stem cell research can be very important and an interesting topic to study and or learn about. With the discoveries and beneficial information they have on stem cells it can help cure diseases and change someones life forever. In class we had several conversations; what we thought about it, the benefits, drawbacks, can it be abused, should it be public or private? There's so many things that you can learn from Stem Cell Research, like what Tony Underhill said, " It's the future of medicine."  

What are you planning on doing next ? 

• Something that I definitely plan on doing next is catching up in my Anatomy and Pre-Calc class. I really want to raise my grades in those two classes and I know i'm capable of doing it. I'm just going to have to make a little more time and focus on those two subjects. For right now that's my goal and hopefully by the time the next 3 Questions Blog is due I'll be all caught up. Another thing that i plan on doing are my senior pictures. Hopefully I'll get those done this upcoming Friday, I'm so excited.. but yet nervous. 

Stem Cell Research  

Tissue Blog

In my opinion, I think that the video TEDTalk by Flo Omenetto ties in with cell differentiation because cells are made by the same DNA but have different functions because they are made differently which in other words is known as form and function. Depending on where they are located and the turning off and on of genes to make new proteins giving the cell its own information and instructions of how to work in the body. For example, they can end up being Epithelial tissue and or Connective tissue. Going back to Mr. Omenettos video he explains how all silk is produced by a little insect know as the Silk Worm, but if adding a slight change to the silk it can be used for many different functions. Even though silk is created by the same way it can perform in different functions. Connecting to the physiology of this where silk is made of simply water and protein that can be controlled to have different functions such as replacing a small vein or a bone. It is designed to where it is very strong.  Mr. Omenetto also mentions how the protein in silk can be implanted in the body without having to be retrieved because it reintegrates in living tissue known as being biodegradable and biocompatible. Tying it back to physiology (homeostasis) which is the maintenance of a stable internal enviroment in a way that silk performed as being that extra help for a vein or a bone.

Weekly 3 Questions

Well this week has been very busy and very stressful. It's right before Homecoming week and there's many things going on. On monday we started practicing at 6 in the morning with Pom, so it's been somewhat of a blur to me. My body and mind aren't used to getting up at 5 in the morning and practicing. Even though it's been hectic I enjoyed practicing in the morning because of the fact that I'm a morning perso and it felt good to go straight home after school after a long day. I recently finished learning all of my new choreography parts in our Homecoming performance dance. Also I recently completed my first exam in my Medical Terminology class. I was very nervous to take this test because it was worth a lot. I haven't seen my results on how I did but I went in and I was confident in myself so I'm hoping it's a good grade. 

Well in my Anatomy class I learned how to use a microscope correctly, and I'm learning many new things about tissue: Epithelial Tissue, Connective Tissue, and there functions as a cell tissue. I never new how detailed a single type of cell tissue was and it's uniqueness. Also each time I go to my Medical Terminology class I learn something new about the body and how it works. It fascinates me to know how everything in your body works together and what is in charge of what and just everything that happens in your body.

What I'm planning on doing next is preparing for our Homecoming performance on thursday and saturday. I'm extremely nervous for that and just thinking about it makes my stomach hurt. I'm gonna work extra hard at practice and school. I also want and need to set my prioritites straight and focus more on school because I've been stressing over too many things and i'm just losing my focus.

3 Questions

What tasks have you completed recently ?

• Some tasks that I completed recently are getting some of my tumbling and taking a test. Both taking this test and throwing my tumbling were pretty important to me, since they had deadlines on when I had to do them it was starting to stress me out. No matter how much I would study or how hard I would work it was still taking a toll on me. Everyday I came home to study for my test whether it was 15 minutes or an hour I was determined to be that much more prepared. Same with my tumbling, after practice I would head straight to the gym and starting working on my tumbling. There were countless times were I would mess up and occasionally fall pretty hard, but I got up and tried again. Like they say, " practice makes perfect". 

What have you learned recently ?

• Throughout the tasks that I completed I learned a lot. First I learned that hard work does pay off. It feels good to know that you put in so much time and effort and was determined to get it done. There's times were I feel that no one sees how hard I'm working and it upsets me. But what I truly learned was that no one has to be a witness to your hard work or your dedication. The thing that matters the most is that you know what you did, you know how hard you worked, and you know you put in 110 percent towards it. Also I took the quote, " practice makes perfect " into thought. And I came to realize that practice can mean perfecting something in your opinion or practice can be permanent. In your mind you might think something is perfect because that's the way you feel about it, but in reality nothing is perfect. So practice can also mean permanent, because what you practice and get done at school, at practice, or anywhere else is exactly what you're going to get somewhere else when you do it. 

What are you planning on doing next ?

• What I'm planning on doing next is passing my test and achieving my goal in tumbling. Yes it is going to take time and hard work and dedication but I'm up for the challenge. With any obstacle that comes my way I will try my best. Maybe along the way I learn new things.

Passion...

Passion is something when you have no words to describe how or what you feel for something or someone. It's an emotion, feeling, and or a desire. You can have a passion for anything or anyone your heart desires to have a passion for.

For example, one of my passions is cheer and dance! Since I was a little girl my mom had me in dance classes and cheer classes. Now that I am older and in high school, I've leaned more towards participating in cheer. Even though sometimes cheer can get really hard I wouldn't know what it would be like if it wasn't in my life. Cheerleading is sometimes my escape from everything else I have going on in my life, it is like the gym is my second home and all my team mates are my second family. I've grown really close to cheer and some of the people in it and that is why it is one of my passions.
