Hormones are non nutrient chemicals, which act as intracellular messengers and are produced in trace amounts. Endocrine cells are present in different parts of the gastrointestinal tract, e.g., gastrin, secretin, GIP. Atrial wall of our heart secretes a peptide hormone called ANF (Atrial Natriuretic Factor), RH/HH are produced by hypothalamus. Adenohypophysis is not directly under neural control, it is under the control of hypothalamic hormones, brought by portal system.

Held on 30 Apr 2013 · Verified 9 Jul 2026.
Options
- A
Adenohypophysis is under direct neural regulation of the hypothalamus
- B
Organs in the body like gastrointestinal tract, heart, kidney and liver do not produce any hormones
- C
Non-nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones
- D
Releasing and inhibitory hormones are produced by the pituitary gland
