Final answer:
The pudendal nerve is involved in controlling urination and provides voluntary control of the external urethral sphincter. It also plays a role in controlling the muscles of the perineum in both males and females. The pudendal nerve is important for the proper function of the urinary system.
Step-by-step explanation:
The pudendal nerve is one of the nerves involved in control of urination. It is responsible for providing voluntary control of the external urethral sphincter, which helps maintain continence during filling of the bladder. The pudendal nerve arises from the sacral region of the spinal cord and travels via the S2-S4 nerves of the sacral plexus.
In both males and females, the pudendal nerve plays a role in controlling the muscles of the perineum, including the muscles surrounding the anus and the muscles that compress the urethra during urination or ejaculation.
The pudendal nerve is important for the proper function of the urinary system and the control of urination.
