MSH released from | APG; corticotropes |
MSH action | + melanocyte to produce skin pigment |
Hormone: Follicle stimulating hormone FSH, triggered by: | GnRH |
FSH released from | APG; gonadotropes |
FSH action | + gamete maturation + spermatogenesis |
Hormone: Lutenizing Hormone LH, triggered by | GnRH |
LH released from | APG; gonadotropes |
LH action | + production of testosteron + production of estrogen and progesterone |
