Follicle stimulating hormone-in males regulates spermato genesis with androgens
Growth and development of Ovarion follicles in females

Question 4

Hormones of Pars intermediate

Answer 4

Melanocytes stimulating hormone
Acts on melanocytes(Melanie containing cells) and regulate pigmentation of the skin

Question 5
