Function Of Muscular System Quiz Questions

Muscles play a crucial role in enabling movement in the body. They are responsible for contracting and relaxing, which allows us to perform various actions such as walking, running, and even blinking. Without muscles, our bodies would be unable to move or perform any physical activity. Therefore, the statement "Muscles are responsible for your body's every move" is true.

Cardiac muscles are unique in that they have the ability to contract automatically without any external stimulation. This automatic contraction allows the walls of the heart to squeeze inward, which is essential for pumping blood throughout the body. Unlike skeletal muscles, which require conscious control from the nervous system, the cardiac muscles have their own internal pacemaker system that initiates and coordinates the contractions. Therefore, it is true that cardiac muscles contract automatically to squeeze the walls of the heart inward.

Skeletal muscles make up fifty percent of your body weight.

A muscle makes itself smaller when it contracts and larger when it relaxes.

This would be in places like the stomach, intestines, blood vessels and the bladder.
