External genitalia -parts
- 2. female genital organs are classified into: 1- Internal Genitalia 2-External Genitalia Internal Genitalia: include: • 1- Vagina • 2- Uterus • 3- Fallopian Tubes • 4- Ovaries
- 3. o vulva/pudendum:-includes all visible external genital organs in perineum. o Consists of Mons pubis Labia majora Labia minora Hymen Clitoris Vestibule Urethra Bartholin’s gland EXTERNAL GENITALIA
- 4. Female External Genital Parts
- 5. • Mons Pubis The mons pubis is also termed as mons veneris.It is the fat pad covering on the pubic bone which segments to create labia majora. The main purpose of mons pubis is to give cushioning and also protect the bones and tissues lying beneath. Female External Genital Parts
- 6. • Labia Majora The labia majora are two prominent longitudinal cutaneous folds that extend downward and backward from the mons pubis to the perineum. The labia majora is homologous to the male scrotum.
- 7. • Labia Minora The labia minora (singular: labium minus), also known as the inner labia, nymphae, are two flaps of skin on either side of the human vaginal opening, situated between the labia majora (outer labia, or outer lips). They vary widely in size, color, and shape from individual to individual.
- 8. • Clitoris The clitoris is a small, sensitive organ located at the top of the vulva, just above the urethra and the vaginal opening. The clitoris is the human female's most sensitive erogenous zone and generally the primary anatomical source of human female sexual pleasure.
- 9. • Prepuce A fold of skin that surrounds and protects the glans of the clitoris; it also covers the external shaft of the clitoris, develops as part of the labia minora and is homologous with the foreskin in male genitals. The prepuce is important not only in protection of the clitoral glans, but also in pleasure, as it is an erogenous tissue.
- 10. URETHRA • External Urethral Orifice The external urethral orifice (urinary meatus) is the external opening of the urethra, from which urine is ejected during urination. It is located about 2.5 cm behind the glans clitoridis and immediately in front of the vagina in the vulval vestibule of the female genitalia.
- 11. • Internal Urethral Orifice The internal urethral orifice is the opening of the urinary bladder into the urethra. It is placed at the apex of the trigonum vesicae, in the most dependent part of the bladder, and is usually somewhat crescent-shaped; the mucous membrane immediately behind it presents a slight elevation in males, the uvula vesicae, caused by the middle lobe of the prostate
- 12. • Bartholin's gland The Bartholin's glands (also called greater vestibular glands) are two pea sized compound racemose glands located slightly posterior and to the left and right of the opening of the vagina. They secrete mucus to lubricate the vagina and are homologous to bulbourethral glands in males. Bartholin's glands secrete relatively minute amounts of fluid when a woman is sexually aroused.
- 13. • Fourchette The frenulum of labia minora (fourchette or posterior commissure of the labia minora) is a frenulum where the labia minora meet posteriorly.
- 14. Blood supply: -vaginal artery: branch of IIA -vaginal branch of the uterine artery - vaginal plexus drains into IIV Lymphatics • Inguinal group of lymph nodes (Upper medial horizontal lymph node)
