The role of muscles in the movement of the forearm.

The video explains the muscular system's role as the body's engine, generating movement through muscle contraction and relaxation. It details how forearm movement involves the contraction and relaxation of muscles with the help of the elbow joint and tendons. The importance of maintaining a healthy muscular system is emphasized, highlighting the connection between muscles and bones via tendons.

What role does the muscular system play in the body?

• It is responsible for the body's immune response.

• It acts as the body's engine, generating mechanical energy and movement.

• It controls the body's digestive processes.

• It regulates the body's temperature.

How do muscles in the forearm work when you lift your arm?

• The front muscle relaxes and the back muscle contracts.

• Both muscles contract simultaneously.

• Both muscles relax simultaneously.

• The front muscle contracts and the back muscle relaxes.

What happens to the muscles when you lower your arm?

• Both muscles relax simultaneously.

• The front muscle contracts and the back muscle relaxes.

• The front muscle relaxes and the back muscle contracts.

• Both muscles contract simultaneously.

Why is it important to take care of the muscular system?

• Because it helps in digestion.

• Because it regulates blood pressure.

• Because it is linked to bones by tendons, affecting movement.

• Because it controls the nervous system.

What is the function of tendons in the muscular system?

• They store nutrients for muscle use.

• They link muscles to bones, transferring muscle actions.

• They generate energy for muscle contraction.

• They produce hormones for muscle growth.
