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.
