MUSCLE PHYSIOLOGY

Detailed explanation-1: -It is found throughout the urinary system where it functions to help rid the body of toxins and works in electrolyte balance. It is found throughout arteries and veins where it plays a vital role in the regulation of blood pressure and tissue oxygenation.

Detailed explanation-2: -The detrusor smooth muscle is the main muscle component of the urinary bladder wall. Its ability to contract over a large length interval and to relax determines the bladder function during filling and micturition.

Detailed explanation-3: -Smooth muscle, found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus, is under control of the autonomic nervous system. Smooth muscle cannot be controlled consciously and thus acts involuntarily.

Detailed explanation-4: -Urethral smooth muscle consists of an inner longitudinal layer and an outer circular layer. The longitudinal muscle shortens during micturition and circular smooth muscle contracts to maintain continence, especially in the longer male urethra.

Detailed explanation-5: -smooth muscle, also called involuntary muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus.
