THE BLADDER AND URETHRA

tures of the caudal pelvic region. The distal cutaneous branch supplies structures of the ventral perineum (before it becomes superficial by emerging from the ischiorectal fossa), crosses the medial process of the ischial tuber (where it may be palpated), and supplies the vulva and perineal skin; some branches extend as far as the nearest part of the udder. The depleted trunk passes ventral to the vagina before leaving the pelvis in company with the internal pudendal artery; it supplies the dorsal nerve of the clitoris and supplies other branches to the skin of the udder. (In the male, the corresponding branches are the dorsal nerve of the penis and cutaneous branches to the scrotum and prepuce.)
