The internal organs of generation are the vagina and uterus with its appendages; but I will first describe the urethra and the perineum.

The URETHRA is a membranous dilatable canal about an inch and a half in length, and directed obliquely from before backwards, and from below upwards, running under and behind the symphasis pubis, from which it is separated by loose celular tissue. Its inferior portion is intimately united to the vaginal walls. Its meatus, the outlet for the urine, is situated about an inch from the clitoris, and immediately above the prominent enlargement of the anterior part of the vagina.

Internally the urethra opens into the bladder. Its direction is subject to variation during pregnancy, the bladder being carried upwards with the uterus, the urethra curves under the pubic arch, and then ascends perpendicularly. The same change occurs when the uterus is enlarged from other causes. In prolapse of the pelvic viscera the course is reversed.

The PERINEUM is the portion between the rectum and the vagina.
