Study Notes
Uterine Cycle Overview
- All statements about the uterine cycle are true except that FSH and LH directly promote the development of the uterine endometrium.
Effects of Estrogen
- Estrogen promotes growth of breast tissue during puberty.
Polar Bodies Formation
- Three polar bodies may be found with a mature ovum; one arises from an unequal division of the ovum while the other two come from the division of the first polar body.
Progesterone Function
- Secretion of progesterone prepares the mammary glands for lactation.
Corpus Luteum Maintenance
- If fertilization occurs, the developing embryo secretes a hormone that maintains the corpus luteum.
Genetic Variability
- The statement that crossing over provides genetic variability in meiosis while independent assortment does so in mitosis is false.
Spermatogenesis vs. Oogenesis
- The key difference is that oogenesis produces one mature ovum from the parent cell, whereas spermatogenesis produces four mature sperm.
Trigger for Ovulation
- Luteinizing Hormone (LH) is the necessary trigger for ovulation.
Uterine Tubes
- The infundibulum is the funnel-shaped section of the uterine tube located near the ovary.
Post-Ovulation Changes
- Immediately after ovulation, the endometrium enters its secretory phase.
