Describe how glycoprotein hormone family is secreted:
1. name the members of glycoprotein hormone family 4
2. Pathway 3, 3, 7
1. FSH, LH, TSH, and chorionic gonadotropin
Pathway: GnRH (hypothalamus) --> FSH/LH (ant pit) --> testosterone, estrogen, and dihydrotesosterone (ovaries and testes)
FSH/LH --> CG (embryo/placenta); earliest sign of pregnancy, maintains implantation and pregnancy.
TSH: Thyroid RH (hypothalamus) --> TSH (ant pit) --> binds to receptors on cells of thyroid gland --> cAMP --> PKA --> secretion of T4 and T3 --> T3 interacts with IC receptors, altering transcription.
