Study Notes
External Female Reproductive Structures
- Mons Pubis: A thick fold of fat located above the symphysis pubis.
- Escutcheon: Medical term for pubic hair.
- Labia Majora: Thick folds of adipose tissue, highly vascular, with anterior and posterior commissure.
- Labia Minora: Thinner folds of adipose tissue, less vascularized than labia majora.
- Clitoris: Key structure for female arousal; sensitive and aids in catheterization.
- Urethral Meatus: Passageway for urine located below the clitoris.
- Vestibule: Area between the labia minora containing multiple openings (vulvar holes).
- Smegma: Cheese-like substance that can accumulate around the clitoris.
- Hymen: Membrane separating internal and external genitalia.
Fallopian Tubes
-
Structure: Tubes through which eggs travel from ovaries to uterus, with four distinct sections:
- Isthmus: Narrowest part; site for bilateral tubal ligation.
- Interstitial: Most proximal segment.
- Ampulla: Longest section; primary site for fertilization.
- Infundibulum: Widest end, most distant from uterus.
-
Functions:
- Transport ovum to the uterus.
- Site of fertilization.
- Nourish the ovum during transit.
Ovaries
- Description: Small, oval-shaped glands responsible for producing and storing eggs.
-
Key Terms:
- Oogonia: Immature egg cells, with counts decreasing from 600k at 2 months intrauterine to about 30k-40k at age 36.
- Oocyte: Mature egg cells, with approximately 2 million at birth and none at menopause.
-
Functions:
- Production of hormones.
- Oogenesis (egg cell production).
- Ovulation process.
Internal Female Reproductive Structures
- Vagina: Hollow, muscular canal located behind the bladder and in front of the rectum.
- Cul-de-sac Douglas: Space between rectum and vagina; pH changes from alkaline pre-puberty to acidic post-puberty assisted by Doderlein bacilli.
Trivia and Noteworthy Points
- Grafenberg Spot ("G-spot"): Located 1-2 inches inside the anterior portion of the vulva; noted for heightened sensitivity compared to the clitoris.
- Women are more likely to experience UTIs due to shorter urethra compared to men.
- Sperm viability in acidic vs. alkaline environments: female sperm survive longer in acidic conditions, while pregnancy causes a slight shift to alkalinity.
