Corpus luteum, luteinization and progesteron production and regression of the Corpus Luteum occurs during the ____ cycles |
estrus
diestrus |
|
|
____ cycle is 21 days, and the ____ cycle lasts for 4-7 days. The ___ cycle lasts for about 14-15 days.
|
Estrous
Estrus Diestrus |
|
|
hypothalamus releases gonadotropins ( releasing hormones). In the Estrus stage, the follicle grows, and matures, At maturation, _____occurs.
|
ovulation
|
|
|
Hypothalamus releases the gonadotropins/ releasing hormones (GNRH) into the anterior pituitary, and it sends FSH, and LH to the ovary. In the follicle stage(estrus), estrogen high. LH and FSH are seen, but not as high as estrogen. in the diestrus stage of the corpus luteum, progesterone is high, estrogen lower.
