Anatomical terms of muscle

Anatomical terms of muscle are just special words we use to describe different parts of our muscles inside our bodies. Imagine your muscles are like a big puzzle made up of different parts. Each part has a special name that helps us understand where it is and what it does.

First of all, muscles are made up of little pieces called fibers. These fibers work together to make your muscle contract, or get smaller and tighter. When your muscles contract, they help your body move and do all sorts of things.

Now, let's learn some special words to describe the different parts of our muscles. The place where your muscle starts is called the origin. This is the part of the muscle that connects to a bone, and it's usually the part that doesn't move much when you use the muscle.

The other end of the muscle is called the insertion. This is the part of the muscle that moves when you use it, and it connects to another bone or a joint. So when your muscle contracts, the insertion moves closer to the origin.

Now, let's talk about some different directions you might hear when we talk about muscles. Longitudinal muscles are muscles that run parallel to the long axis of your body. They help you move forward and backward, like when you walk or run.

Circular muscles, on the other hand, are muscles that form rings or circles. They help with things like squeezing and pushing, like when you close your eyes tightly.

Finally, there are diagonal muscles. These muscles are at an angle, and they help you move in different directions. For example, the muscles in your arms that help you move them up or down are diagonal muscles.

So, in short, anatomical terms of muscle are just special words we use to describe different parts of our muscles. These words help us understand where the muscle is, what it does, and how it works.
