Definition
- Endometrium: inner lining that thickens each cycle in preparation for possible implantation
- Myometrium: middle, muscular layer that contracts during labor and menstruation
- Perimetrium: thin outer covering
|
|
|
Term
|
Definition
- Menstrual Phase (Days 1–5): The endometrium is shed, resulting in menstrual bleeding.
- Follicular Phase (Days 1–13): FSH stimulates the growth of follicles in the ovary. Estrogen levels rise, helping rebuild the endometrial lining.
- Ovulation (Day 14): Triggered by a surge in LH, a mature egg is released from the ovary.
- Luteal Phase (Days 15–28): The ruptured follicle becomes the corpus luteum, which secretes progesterone to support a potential pregnancy. If no fertilization occurs, hormone levels drop and menstruation begins again
