Study Notes
Multiple Choice Questions
- Ovarian Cycle: Ovulation occurs when the mature egg is released by the ovary, leaving through the oviduct.
- Hormonal Regulation: Progesterone thickens the uterine lining, preparing it for implantation, and inhibits FSH and LH.
- Fertility Window: The 14th day of the ovarian cycle is typically the most fertile.
- Female Reproductive System: Ovaries produce estrogen and progesterone, which have various functions. These functions include regulating the menstrual cycle and developing secondary sexual characteristics.
- Seminal Vesicle: The seminal vesicle neutralises acidity in the urethra, providing energy for sperm.
True/False Questions
- Corpus Luteum: The corpus luteum secretes estrogen to help maintain the uterine lining during the luteal phase.
- Sperm Structure: Sperm cells have a head, cytoplasm, and tail.
- Ovulation Trigger: Luteinizing hormone (LH) triggers ovulation, releasing an egg.
- Menstrual Phase: The menstrual phase begins on approximately the 15th day and lasts until the cycle ends.
Ovarian Cycle Sequence
- Follicular Phase (A-J):
- Primary follicles mature into secondary follicles, estrogen levels rise (21).
- Dominant follicle develops, estrogen continues to rise (26).
- Mature follicle ruptures, releasing the egg (24) - ovulation.
- Luteal Phase:
- Ruptured follicle becomes the corpus luteum, producing progesterone (22).
- Progesterone levels rise, supporting uterine lining for potential implantation (29).
- If fertilization does not occur, corpus luteum degenerates, progesterone levels drop (25).
- Menstruation begins (23), marking the start of a new cycle (28).
