#Unit 7. System Physiology – Animal
  1. The anterior pituitary gland becomes unresponsive to the stimulatory effect of gonadotropin releasing hormone (GnRH)
  2. Estrogen from the developing follicles exerts a feedback inhibition on the hypothalamus
  3. The rise in body temperature inhibits hypothalamic release of GnRH
  4. Secretion of estrogen and progesterone by the corpus luteum suppresses hypothalamic secretion of GnRH and pituitary secretion of LH

what is degree of freedom
1- Degrees of freedom represent the number of ways in which the observed outcome categories are free to vary.
2- Degree of freedom refers to the minimum number of logically independent values, which are values that have the freedom to vary in the data sample.
