External sphincter muscle of male urethra

External sphincter muscle of male urethra is a muscle that surrounds the urethra in males. It is responsible for controlling the flow of urine from the body. The muscle is located in the pelvic region and is part of the urinary system.

Etymology

The term "sphincter" comes from the Greek word "sphinkter," which means "band" or "girdle." The term "urethra" comes from the Greek word "ourethra," which means "urinary canal."

Anatomy

The external sphincter muscle of male urethra is a circular muscle that surrounds the urethra. It is located in the pelvic region, just below the prostate gland. The muscle is composed of smooth muscle fibers, which allow it to contract and relax in a controlled manner.

Function

The primary function of the external sphincter muscle of male urethra is to control the flow of urine from the body. When the muscle is relaxed, urine can flow freely from the bladder through the urethra and out of the body. When the muscle is contracted, it constricts the urethra, preventing the flow of urine.
