Q

LH

Leutinizing Hormone

A

stimulates theca interna cells to convert cholesterol to Androstenedione

LH Surge causes ovulation, LH surge caused by Estrogen peak

Q

FSH functions

Follicle Stimulating Hormone

A
  1. jump starting follicles
  2. stimulates diversion of granulosa cells
  3. stimulates produciton of estrogen by granulosa cells using Aromatase and Androstenedione
  4. granulosa cells produce inhibin negative feedback to Ant. Pit,

Q

Progesterone

A

causes endometrium to produce secretions, helps being secretory phase

17
Q

Corpus Albicans

A

Coperus Luteum if it does not get fertilized, loss of progesterone and estrogen, spasms of spinal arteries of endometrium, results in hypoxia of the endometrium causing menstration

18
Q

Menstrual Cycle

A
  1. 1-4 - Menstuation
  2. 5-14 Proliferative Phase
  3. 14 - ovulation
  4. 14-28 secretory phase
  5. repeat
19
Q

Corpus Luteum in fertilization

A

Embryo produces HCG which maintain corpus luteum

20
Q

HCG

A

produced by embryo, maintains corpus luteum, only important for the first 90 days(until the placenta is fully formed and produces its own progesterone)
