(ii) Trophic hormones - Hormones controlling activity of other endocrine glands and growth, e.g. anterior pituitary hormones like thyrotropin for thyroid.

(iii) Hormones connected with Reproduction. FSH, LH (ICSH), oxytocin are sex hormones. (iv) Hormones connected with Growth and Development. GH (somtotrophin), thyroxine.

(v) Hormones of Digestive system. Gastrin, secretin, enterocrinin etc.
