Skeletal Bones:
What are bones? :
Bones are in my opinion one of the least complex systems of human anatomy. All 206 bones serve many purposes to us that is normally taken for granted. Essentially they are the main framework to our bodies. Bones are often thought of as hard and non-flexible; which in some was is true. However when they are still 'alive' they have flexibility to them so we are able to move freely. Think of it this way if our skeletons were as tough as your 7th grade Mr. Bones would you really be able to do all of your everyday actives? The answer to that question is no, simply because they would be more fragile. Why would they be more fragile? It seems silly to think that but really if they weren't a mushy consistency there would be no leeway for when you jump off a park swing, or when you attempt a somersault. We would be much more prone to breaks and fractures. Though doing the previously mentioned may cause some pain the older you get your thankfully not likely to break anything.
All in all bones help us every day without even knowing it.
What are they made of and how do they grow?
Bones are made of collagen tissue, which is living. It's important that they are made of collagen fibers because though they are the strongest fibers and tissues. What is collagen? Collagen is a protein that allows soft framework with the aid of calcium phosphate. Calcium phosphate is a mineral which will harden the framework. Together they provide the flexibility required to facilitate movement and hold up against the challenge of time and stress. Aside from movement the collagen also allows for growth in bones which begins before birth at the earliest stages of development until after puberty; which is normally from 15-17 years of age.
What purposes do they serve to our bodies?
Bones are here to protect us and our organs. For example the rib cage and sternum are there to protect our heart and lungs, also known as the chest cavity. The Skull protects our brain and eyes. They are also present to provide structure to our bodies and holding us up and giving us form or shape. Most Importantly they are a main source of storage for vitamins, minerals, nutrients and lipids. They also are responsible for producing blood cells, both white in red. Which in turn helps our body fight off infections.
Are there diseases linked to bones?
There are many disease that can attach bones.
- Bone Cancer - Can begin in any one bone. Most common in long bones and pelvis. There are several different kinds of bone cancer.
- Osteogenesis Imperfecta - A genetic disorder when bones are easily broken from little or no real cause.
- Osteoporosis - When body looses to much bone, doesn't make enough bone, or both. Causes weakness and clauses to form on bones causing pain.
- Metabolic Bone Disease - Decreased bone strength caused by irregular amounts of vitamins and minerals
- Osteopenia - Weak bones, meaning they break easily.
- Paget's- No regulation of bones cause them to become weak and misshapen.
- Ostemalacia- In which bones soften, normally linked to Vitamins D and or C deficiency.
- Arthritis - Inflammation of one or more joints, causing movement to be difficult and painful.
- General Pain - Normally related to something above.
What do our bones protect?
Simply put, not all our bones server the purpose of protecting organs.
The skull has the job of protecting our brain.
The rib cage protects our heart and lungs.
All 24 spinal vertebral and the Coccyx protects the spinal cord.
What protects our bones?
There is really no one answer as to what protects our bones, I suppose we could put the muscular system here. In short the muscular systems main purpose is to again provide protection, facilitate movement, and hold our bone structure in place.
