PATHOLOGY

Detailed explanation-1: -It is a secondary sphincter to control the flow of urine through the urethra. Unlike the internal sphincter muscle, the external sphincter is made of skeletal muscle, therefore it is under voluntary control of the somatic nervous system.

Detailed explanation-2: -The external urethral sphincter is composed of striated muscle and is located distally and inferiorly to the bladder neck in women between the vaginal orifice and clitoris.

Detailed explanation-3: -The external anal sphincter is largely under voluntary control by the somatic nervous system, which allows it to stay in a contracted state. The muscle is voluntarily relaxed during defecation to allow the passage of feces.

Detailed explanation-4: -The external sphincter muscle surrounds the area of the urethra outside the bladder. It is the secondary muscle in control of urine flow. It is made of skeletal muscle and is a voluntary muscle.
