What structure does the meatus belong to in the male anatomy?

The meatus is the external opening of the urethra, which is a crucial structure in the male anatomy. The urethra serves multiple functions, primarily the transport of urine from the bladder and the ejaculation of semen during sexual activity. The meatus specifically acts as the exit point for these fluids, facilitating their expulsion from the body.

Understanding the relationship between the meatus and the urethra is essential, as it highlights the anatomical pathway through which bodily fluids are expelled. The other structures listed—testes, scrotum, and epididymis—are all involved in the reproductive system, but they do not directly relate to the function or location of the meatus. The testes produce sperm and hormones, the scrotum holds and protects the testes, and the epididymis is where sperm mature and are stored. However, none of these structures are involved in the function of the meatus itself, which is strictly associated with the urethra.
