This is basically part two of my previous post about the Integumentary System, but this post is ALL about the Skeletal System. And if you read my "About " section, you will learn that I don't know how to blog, its just not my thing. I'm more of a poster and projects on paper kind of girl. Anywho, I still don't know how to blog so stick with me here.
Let's start off by saying that the human body contains over 270 bones, however after growth and whatnot, some bones fuse together leaving our body with a (still massive number) 206 bones in our count. To break that down a tad bit.

It looks like a lot of labeling, but the picture actually leaves out a lot of the specifics. Moving on, what would we be without bones? A little tidbit for you: there is an episode of Family Guy where the dad, Peter Griffin finds this lamp, rubs it, and a genie appears to grant him three wishes. One of his wishes, the last one, is when Peter wishes that he had no bones. To make my point, he was just a blob of organs.THAT is where we'd be if we had no bones.
Bones aren't there to only support our bodies though, they also provide protection. Inside our bodies lies very important organs. Our ribs act as a cage (ha ha... rib cage) for our heart, lungs, and from the back, out liver, kidneys, stomach, and intestines. But wait, there's more! They aren't just bones.
One type of bone are long bones which are longer than your average bone. These long bones are hard and dense bones that provide the majority of strength, structure and mobility. They make up about 25% of our overall height and are found in our legs, arms, thighs, and forearms. There are also short bones which are identified as cube-shaped with nearly equal vertical and horizontal lengths. Short bones are generally found in the ankle and wrists. Furthermore, there are bones known as flat and also irregular. Flat bones are thin, flattened bones that are generally curved. Most of the bones in the cranium are flat bones. On the other end, irregular bones fit in none of the above categories. They are primarily spongy bones that are covered with a thin layer of compact bone. In all of these bones, there are holes, smooth facets, depressions, projections, lines, and other markings which give them distinct characterizations and act as passageways for nerves, points of attachment for tendons and ligaments, or points of articulation with other bones.
On a completely separate note, when you tear a muscle it hurts super bad. When you tear a tendon or over-extend a ligament it also hurts super bad. BUT when you break a bone, its sickening. I, personally, have never broken a bone but i have dislocated several on several occasions. I dislocated my big toe on my right foot during a marching band rehearsal (sounds odd but it's totally possible and it hurts super bad). I have also dislocated my pinky finger on my right hand 3 times and on my left, jammed and then dislocated. I kinda got it stuck in a board on my deck because I fell and then I pulled it out without thinking. It hurt so much. But back to breaks, I was standing right by my best friend as she tripped, fell, and caught herself weird with her arm. That snapping sound cannot be imitated. This isn't a clip of my friend but it's a similar situation. What a way to conclude blog #2!
That would be the snapping if his tibia and fibula...
