2. INTRODUCTION The external genitalia are known collectively as the vulva Consists of the following: Labia majora and Labia manora Vestibule Vestibular glands ( Bartholin’s gland) Clitoris Vaginal orifice Hymen 2

3. LABIA MAJORA (1/2) Singular: labium majus These are the two large folds forming the boundary of the vulva. Composed of skin, fibrous tissue, fat and large numbers of sebaceous glands. Anteriorly the fold join in front of the symphysis pubis, and posteriorly merge with the skin of the perineum At puberty, hair grows on the mons pubis and on the lateral surfaces. 3

4. LABIA MAJORA (2/2) Function: to cover and protect the inner, more delicate and sensitive structures of the vulva, such as the labia minora, clitoris, urinary orifice, and vaginal orifice. 4

5. LABIA MINORA ‘Smaller lips’ A pair of thin cutaneous folds that form part of the vulva, or external female genitalia. Function as protective structure for the clitoris, urinary orifice, and vaginal orifice. In fact, the labia minora show a considerable amount of variation in length, width, shape, and pigmentation between individuals 5

6. VESTIBULE It is the cleft between the labia minora The vagina, urethra and duct of the greater vestibular gland open into the vestibule. The borders of the vulva vestibule are formed from the edge of the labia minora. 6

7. VESTIBULAR GLANDS Bartholin's glands also known as the greater vestibular glands are two pea-sized glands located slightly lateral and posterior to the vagina opening. Function is to secrete a mucus-like substance within the borders of the labia minora. This mucus functions as a lubricant to decrease friction during intercourse and a moisturizer for the vulva. 7

9. CLITORIS (1/4) a sex organ in females that functions as a sensory organ. 9 It contains thousands of nerve endings that make it an extremely sensitive organ The clitoris can be divided into three major regions: the glans, body, and crura . The clitoris is a small projection of erectile tissue in the vulva of the female reproductive system.

10. CLITORIS (2/4) Extending from the crura is the body , the main cylindrical region of the clitoris, which contains two columns of the erectile tissue. Blood filling the hollow chambers of the erectile tissue allows the clitoris to grow in size and harden during sexual stimulation. 10 Under the surface of the skin, two legs of erectile tissue known as the crura fan out to support the exterior structures of the clitoris and attach to the underlying tissues.

11. CLITORIS (3/4) Finally, the  glans  forms the pointed tip of the clitoris extending outward from the body and beyond the prepuce that covers the rest of the clitoris. Thousands of touch and pressure sensitive nerve endings are found throughout the clitoris 11 Nerve endings in the body and glans are sensitive to direct touch and pressure stimulation from outside of the body while the nerve endings of the crus are sensitive to stimulation from within the vagina

12. CLITORIS (4/4) The nerve end stimulation is responsible for the majority of sexual pleasure and sensation in the female body. 12

13. VAGINAL ORIFICE Also called the  vaginal vestibule or introitus , is the opening into the vagina. It's located between the urethra and the anus 13

14. HYMEN Hymen is  a piece of tissue covering or surrounding part of your vaginal opening . Its made of a thin layer of mucous membrane. It's formed during development and present during birth. It thins over time and tears. Some people will feel pain or bleed when their hymen breaks, but most will not notice. 14

15. MONS PUBIS The mons pubis is a tissue mound made up of fat located directly anterior to the pubic bones. This mound of tissue is prominent in females and is usually covered in pubic hair. The mons pubis functions as a source of cushioning during sexual intercourse. The mons pubis also contains sebaceous glands and also induce sexual attraction. 15

16. PERINEUM The perineum is the area extending from the base of the labia minora to the minora to the anal canal. It is roughly triangular and consists of connective tissue, muscle and fat. It gives attachment to the muscle of the pelvic floor 16
