Female Reproductive System 🌸
Your body’s reproductive “team” works together to make ovulation, fertilisation, pregnancy, and birth possible :contentReference[oaicite:0]{index=0}.
Quick Snapshot 📍
- Ovaries — make eggs (ova) & hormones.
- Oviducts / Fallopian Tubes — guide the egg toward the uterus.
- Uterus (Womb) — shelters the embryo/fetus.
- Cervix — narrow gateway between uterus & vagina.
- Vagina — elastic birth canal.
- External Genitalia — protective outer structures.
- Mammary Glands — produce & deliver milk.
Digging Deeper 🔎
1. Ovaries 🥚
Two almond-shaped ovaries sit on either side of the lower abdomen, each about 2 – 4 cm long :contentReference[oaicite:1]{index=1}. They attach to the pelvic wall and uterus via ligaments. A thin epithelial “jacket” surrounds an ovarian stroma that splits into an outer cortex and inner medulla. The cortex houses growing follicles, while the medulla holds blood vessels and nerves. Besides releasing an ovum every cycle, the ovaries secrete steroid hormones that drive female characteristics and the menstrual cycle.
2. Fallopian Tubes (Oviducts) 🚴♀️
Each tube spans roughly 10 – 12 cm :contentReference[oaicite:2]{index=2}. Closest to the ovary is the funnel-shaped infundibulum whose fringe-like fimbriae “catch” the egg right after ovulation. The tube then widens into the ampulla (common fertilisation site) before narrowing into the isthmus, which meets the uterus.
3. Uterus (“Womb”) 🤰
The single uterus resembles an inverted pear and is held in place by pelvic ligaments :contentReference[oaicite:3]{index=3}. It opens downward into the vagina through the cervix; the cervix’s channel plus the vagina together form the birth canal. The uterine wall has three layers:
- Perimetrium — thin outer covering.
- Myometrium — thick smooth-muscle layer that contracts powerfully during labor.
- Endometrium — inner glandular lining that rebuilds and sheds cyclically during the menstrual cycle.
4. Cervix & Vagina 🙌
The cervix’s narrow canal guards the entrance to the uterus, while the vagina serves as a stretchy passageway for childbirth and menstrual flow :contentReference[oaicite:4]{index=4}.
5. External Genitalia (“Vulva”) 🌺
- Mons pubis — fatty cushion with pubic hair.
- Labia majora — larger outer folds that frame the opening.
- Labia minora — delicate inner folds.
- Hymen — thin membrane that may partially cover the vaginal opening; its condition is not a reliable marker of sexual history :contentReference[oaicite:5]{index=5}.
- Clitoris — small, sensitive, finger-like organ located where the labia minora meet.
6. Mammary Glands (Breasts) 🍼
Each breast contains 15 – 20 lobes, and every lobe holds many grape-like alveoli :contentReference[oaicite:6]{index=6}. Milk collects in the alveolar cavities, flows through mammary tubules to larger ducts, converges in a spacious ampulla, and exits via the lactiferous duct when a baby suckles.
NEET High-Yield Concepts ⭐
- Distinguish the cortex and medulla regions of the ovary, plus their functions :contentReference[oaicite:7]{index=7}.
- Know all three parts of the fallopian tube (infundibulum, ampulla, isthmus) and the role of fimbriae in egg capture :contentReference[oaicite:8]{index=8}.
- Remember the uterine wall layers—perimetrium, myometrium, endometrium—and match each to its job (protection, contraction, cyclic changes) :contentReference[oaicite:9]{index=9}.
- Identify external genitalia structures and understand why hymen integrity cannot confirm virginity :contentReference[oaicite:10]{index=10}.
- Trace the milk pathway: alveoli → tubules → ducts → ampulla → lactiferous duct :contentReference[oaicite:11]{index=11}.
