Study Notes
Fallopian Tube
- The fallopian tube has three parts: the isthmus (closest to the uterus), the ampulla (widest part), and the infundibulum (funnel-shaped opening).
Gametogenesis
- Definition: The process of forming gametes (sex cells) through cell division in the primary sex organs.
- Site: In the outer cortex of the ovary.
-
Stages: Three stages - proliferation, growth, and maturation
- During intrauterine life: proliferation, growth, and the first meiotic division (prophase I) occur
- At puberty: Completion of the first meiotic division, the formation of the secondary oocyte begins the second meiotic division and arrests at metaphase II
- Immediately after fertilization: Completion of the second meiotic division to yield the mature ovum and the second polar body.
Spermatogenesis vs. Oogenesis
- Spermatogenesis produces four sperm cells
- Oogenesis produces one mature ovum and three polar bodies.
Causes of Premature Labor
- 20% of cases caused by maternal factors such as diabetes mellitus
Fetal Abnormalities
- Fetal abnormalities can lead to premature labor.
Yolk Sac
- The yolk sac transfers nutrients to the embryo before the placenta becomes functional.
