Study Notes
Menstrual Cycle Regulation
- The cyclic function of the uterus requires the presence and interaction of the hypothalamus, pituitary, and ovary.
Hormonal Involvement
- Estrogen and progesterone hormones are involved in endometrial changes responsible for menstruation, with estrogen stimulating endometrial growth and progesterone preparing the endometrium for implantation.
Absence of Key Elements
- In the absence of the hypothalamus, pituitary, and ovary, the menstrual cycle cannot occur.
Feedback Loops
- Positive feedback loops trigger the LH surge, inducing ovulation, while negative feedback loops regulate hormone levels, preventing overstimulation.
Successful Menstrual Cycle
- A successful menstrual cycle requires the coordinated interaction of the hypothalamus, pituitary, ovary, estrogen, and progesterone.
