Answer:
Mobility: The muscular system's main function is to allow movement. When muscles contract, they contribute to gross and fine movement.
Gross movement refers to large, coordinated motions and includes: Walking, running, swimming
Fine movement involves smaller movements, such as:
Writing, speaking, facial expressions
The smaller skeletal muscles are usually responsible for this type of action.
Stability: Muscle tendons stretch over joints and contribute to joint stability. Muscle tendons in the knee joint and the shoulder joint are crucial in stabilization.
The core muscles are those in the abdomen, back, and pelvis, and they also stabilize the body and assist in tasks, such as lifting weights.
Posture: Skeletal muscles help keep the body in the correct position when someone is sitting or standing. This is known as posture.
Temperature regulation
Maintaining normal body temperature is an important function of the muscular system. Almost 85 percent of the heat a person generates in their body comes from contracting muscles.
When body heat falls below optimal levels, the skeletal muscles increase their activity to make heat. Shivering is one example of this mechanism. Muscles in the blood vessels also contract to maintain body heat.
Body temperature can be brought back within normal range through the relaxation of smooth muscle in the blood vessels. This action increases blood flow and releases excess heat through the skin.
Circulation: The heart is a muscle that pumps blood throughout the body. The movement of the heart is out of conscious control, and it contracts automatically when stimulated by electrical signals.
Respiration: Breathing involves the use of the diaphragm muscle.
Digestion, Vision, Excretion are also important functions of muscles
