The urethromeatus refers to the external opening of the urethra, which is the tube that carries urine from the bladder to the outside of the body. In males, it is located at the tip of the penis, while in females, it is situated just above the vaginal opening. The urethromeatus plays a crucial role in urinary function and can also be involved in reproductive processes in males. Abnormalities or infections in this area can lead to various urological conditions.
