Muscle Cramps

http://img4.realsimple.com/images/health/preventative/0804/body-language-6_300.jpg

Muscle cramps, everyone gets them, but why do we get them? I had always wondered about the cause of muscle cramps and I was glad we were able to spend time this semester discussing what factors cause them. There are actually a few different causes of muscle cramps. These causes include overuse of a muscle, dehydration, inadequate blood supply, and nerve compression. Some of these causes are more serious than others. 

This website gives a more in depth description of what a muscle cramp is, as well as what factors cause them.


This video gives tips on relieving and preventing cramps in athletes.

Tendons Vs. Ligaments

An easy way to transition from the skeletal system to the muscular system, is to discuss tendons and ligaments. Though the distinction between the two is simple, it can become confusing if you are not familiar with the functions of each structure. Ligaments, connect bone to bone. Tendons, attach muscle to bone. 
This website discusses the differences between these two structures further.


This video discusses the ligaments of the knee in detail.

Broken Bones

Not only did I learn about the multiple types of bone fractures (compression, transverse, impacted, etc.), but I also learned about what happens inside the bone when it is broken/fractured.

This video describes what occurs, inside the body, after a bone is broken.

Although the class covered many bones I was unfamiliar with, the bones of the ear were the most unfamiliar to me. The bones of the middle ear are the malleus ("hammer"), incus ("anvil"), and stapes ("stirrup").

Here's a video that shows the functions of these tiny bones.
