Answer:
Gonadotropins are polypeptide hormones and are secreted by the anterior pituitary gland.
Explanation:
Hypothalamus releases GnRH i.e gonadotropin releasing hormone which stimulates the anterior pituitary to secrete gonadotrophs such as FSH, ICSH and LH.
FSH (follicle stimulating hormone): In males it stimulates spermatogenesis. In females it stimulates growth of ovarian follicles.
ICSH (Interstitial cell stimulating hormone): In males, secretion of testosterone.
LH (Luteinising hormone): In femalestogether with FSH, it triggers ovulation, stimulates conversion of broken ovarian follicle into corpus luteum.

A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom.
