An involuntary muscle contraction is called a spasm.
This is due to contraction of the biceps, and is known as flexion.
contracture
The continuous partial contraction of muscle is called muscle tone
Muscles provide movement, especially the skeletal muscles. The smooth muscles in our organs produce movement called peristalsis or tonic contraction which holds sphincters closed.
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
if you're on OdysseyWare your answer would be Active stretching.............. =)
This process is called contraction. Muscles shorten or contract to produce movement.
All muscles cause movement due to the contraction of coupled muscle cells. Perhaps the question intended to inquire about muscles that cause a bending in which the joint angle decreases. Muscles of this type are called flexor muscles (biceps for example).
Urine is expelled from the body by a process called micturition, also known as urination or voiding. It involves the relaxation of the urethral sphincter muscles and contraction of the bladder muscles to expel urine from the body.
Goosebumps on the arms are caused by the contraction of small muscles at the base of hair follicles, called arrector pili muscles. This involuntary contraction is often triggered by emotions, cold temperature, or a sense of danger. The bumps appear when these muscles pull the hair follicles upright, creating the characteristic raised skin texture.
Repeating units of actin and myosin filaments are called sarcomeres. These are designed to control the contraction of muscles in the human body.
Heartbeats are the repeated contraction of cardiac muscles.
