Anatomical terminology

The Perineum is the area of the human body found between the lower end of the vagina and the anus (in females); and the scrotum and the anus (in males). When a person reaches puberty, the size of the perineum is about one inch in length. During puberty, hair will grow around and on the perineum to protect it.

Inside the perineum-area are specialized muscles that perform functions of sexuality, erection and excretion.
