Joints

© Gina Dronenburg

It seems that when we think or talk about physical fitness or education, we think about all sorts of exercises and which muscles we use or don't use. Have you ever thought about the bones and joints as part of fitness? We seem to hear much about when joints are damaged, but do we know any basics about joints? Following, I've included some information you may find interesting:

There are only four kinds of joints. Joints are the parts between two bones that connect the two, and allow the muscles a base to work properly.

The first is the ball and socket joint, and allows movements in many directions. Where our hips and legs, as well as our shoulders and upper arms connect are both ball and socket joints.

The second is the hinge joint. This type of joint allows a movement in only one direction. Examples of hinge joints are those of our elbows and knees.

The third is the pivot joint. This type of joint is a mixture of the ball and socket and the hinge joint. Movements are basically limited though in this type of joint. Examples of the pivot joints can be found in our ankles and wrists.

The fourth is the joints of the skull. Yes, you heard right! Our skull has joints, but these joints are so extremely strong,(because they do not move) that we don't even know they exist!

All of our joint movements are aided by cartilage that is both slippery and smooth. This allows each to be fluid and done with ease.

Join me again for more on our movements, and more about our skeletal systems.

Until next time, become aware of which types of joints you are using on a daily basis! This is a quick and easy way to learn their names!
