1. Outer lips (labia majora)
2. Lips in (labia minora)
3. Clit (clitoris) is very sensitive because many end nerve endings. Clitoris is the most sensitive part in receiving sexual stimulation.
4. Hole genitals (vagina) is located between the hole and pee rectum (anus)
5. The growth of pubic hair as she entered the age of puberty

Follicle is the functional unit of the ovary that is composed of layers
theca cells and the outer layer of granulosa cells, which are separated
by a basal membrane. In the ovarian follicle cells there are a lot of granulosa FSH receptors, whereas in cells many internal thecal LH receptors. Ovary as
endocrine glands produce hormones that are hemokrin,
paracrine, or autocrine include: estrogen and progesterone.
Mature follicles or follicles called preovulatoris (praovulatory
follicle) shaped like an egg, in the middle there fluid-filled antrum and egg follikel located at the center with veiled by layers of granulosa cells
called pelucida zone. Further increases follicle preovulatoris
vaskularisasinya approaching ovulation and follicles simultaneously
is not selected for ovulation had atresia.
