The urethral orifice refers to the external opening of the urethra, a tubular structure that drains urine from the bladder. There are several synonyms for the word "urethral orifice," including urethral meatus, external urethral orifice, and urethral opening. These terms are often used interchangeably to describe the same anatomical structure. However, it is important to note that the term "urethral meatus" can also refer to the internal opening of the urethra within the body. Regardless of the terminology used, understanding the location and function of the urethral orifice is crucial to maintaining a healthy urinary system.
