Muscular System

Why is the Muscular System so important? Without the muscular system we would not be able to move. Without muscle humans would be non-existent.

Functions of the Muscular system

Muscular tendons stabilize joints so that the joints won't move out of place. This would make your bones pop out of place if you bent your arm without these tendons. Muscle helps us stand up, and practically fight gravity. If we didn't have the muscle helping us stand up we would fall from gravity. Moving the skeleton is probably the most useful function that muscle has because without muscle moving our bones how would we move. And the last main useful function that a muscle has is heat production because it obviously keeps us warm.

Types of Muscles

Smooth:

This muscle is involuntary which means its automatically controlled without thinking about it. An example of a smooth muscle is the esophagus. It is used to force food down to you stomach. We never think about it, but it always happens.

Cardiac:
Cardiac muscle is also an involuntary type of muscle. The cardiac muscle is the heart muscle that works on its own.

Skeletal:
The skeletal muscles are voluntary. This is because you do think about where your going or what you pick up. The skeletal muscles are what get you from place to another. The skeletal muscles are attached to the skeleton.

Structure of Skeletal Muscle 

Fascia

The Fascia is only found in the skeletal muscle. This is the covering of the muscle and it becomes the tendons. 

Myofibrals

The myofibrals are in all muscle because they muscle fibers. They are involved in muscle contraction.
