What is the role of the Skeletal Muscles in the body?

Question

Skeletal muscles are contractile elements that rapidly change the length of the cell.

Answer 1

Where you got all that changing the length of the cell is beyond me.

The muscular system as a whole is to hold the body erect and make movements possible. Muscle movement generates nearly 85% of the heat that keeps the body warm..The muscles move the food through the digestives system.. Muscle movements aids the flow of blood through veins as it returns to the heart. Muscle action moves fluids through ducts and tubes associated with other body systems.
The body has more than 600 muscles that make up about 40% to 45% of the bodys weight. These muscles are made up of fibers , covered with fascia, and attached to bones by tendons.
The muscles are composed of long, slender cells known as muscle fibers. Each muscle consists of a group of fibers held together by connective tissue and enclosed in a fibrous sheath
Fascia is the sheet or band of fibrous connective tissue that covers supports and separates muscles. A tendon is a narrow band of nonelastic , dense, fibrous, connective tissue that attaches a muscle to a bone.
An aponeurosis is a flat fibrous sheet of connective tissue that is very similar to a tendon ; however , an aponeurosis attaches a muscle to a bone or to other tissues .
The Three types of muscle tissue are Skeletal, smooth and cardiac

Skeletal Muscles attach to the bones of the skeleton and are the muscles tht make possible body motions such as walking and smiling

Skeletal muscles are also known as striated muscles because dark and light bands in the muscle fibers create a striped appearance

Skeletal muscles are also known as voluntary muscles because we have conscious over these muscles

Answer 2

thier roles are to move your bones
