Skeletal muscle is the type of muscle that controls movement. Problems with these muscles can be minor, life-threatening, or ongoing problems that make it hard to perform basic daily activities.
The muscular system consists of various types of muscle that each play a crucial role in the function of the body. Some muscular system functions include mobility, stability, posture, and circulation.
Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.
