Which of the following statement is correct in relation to the endocrine system?
Adenohypophysis is under direct neural regulation of the hypothalamus
Organs in the body like gastrointestinal tract, heart, kidney and liver do not produce any hormones
Non- nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones
Releasing and inhibitory hormones are produced by the pituitary gland
C.
Non- nutrient chemicals produced by the body in trace amount that act as intercellular messenger are known as hormones
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/IH are produced by hypothalamus. Adenohypophysis is not directly under neural control, it is under the control of hypothalamic hormones, brought by portal system.
Select the answer which correctly matches the endocrine gland with the hormone it secretes and its function/deficiency symptom
| Endocrine gland | Hormone | Function/ deficiency symptoms |
| Anterior pituitary | Oxytocin | Stimulates uterus contraction during child birth |
| Posterior pituitary | Growth Hormone (GH) | Oversecretion stimulates abnormal growth |
| Thyroid gland | Thyroxine | Lack of iodine in diet results in goitre |
| Corpus luteum | Testosterone | Stimulates spermatogenesis |
