tensor veli palatini muscle
the cremaster muscle's function is to raise and lower the testes in order to regulate scrotal temperature for optimal spermatogenesis and survival of the resultant spermatozoa. it does this by increasing or decreasing the exposed surface area of the surrounding tissue, allowing faster or slower dissipation of body heat.









































the cremaster muscle is an involuntary muscle and contraction can occur during arousal which can prevent injury to the testicles during sex.









































retraction can also occur during moments of extreme fear, possibly to help avoid injuring the testes while dealing with a fight or flight situation.

a fasciculation, or muscle twitch, is a small, local, involuntary muscle contraction and relaxation which may be visible under the skin. deeper areas can be detected by electromyography (emg) testing, though they can happen in any skeletal muscle in the body. fasciculations arise as a result of "spontaneous depolarization" of a lower motor neuron leading to the synchronous contraction of all the skeletal muscle fibers within a single motor unit. an example of normal spontaneous depolarization is the constant contractions of cardiac muscle, causing the heart to beat. usually, intentional movement of the involved muscle causes fasciculations to cease immediately, but they may return once the muscle is at rest again.
