Main Function of the Muscular System

- The main function of the muscular system is movement.

- There are three types of muscle tissue: skeletal, cardiac, and smooth.

What are Muscles 4

The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves

Biceps Brachii

One of your muscles are the Biceps brachii. The Biceps brachii crosses both the elbow and shoulder joints. Its action on the shoulder joint is very weak flexion. It supinates the forearm and is a strong flexor of the elbow. The bicep curl exercises is a common one to strengthen this muscle.


Another one of your muscles are Brachialis.

The Brachialis acts to flex the elbow whether in pronation or supination, along with Biceps Brachii. As Brachialis is attached to the Ulna, which cannot rotate, it is the only true flexor of the elbow.
