Solution :-

(a) Hypothalamus:-
Two sorts of hormones are produced by hypothalamus: releasing hormones (that stimulate secretion of pituitary hormones) and inhibiting hormones (that inhibit secretion of pituitary hormones.
These hormones include:
1. Thyrotropin-releasing hormone Adren
2. Corticotropin-releasing hormone
3. Follicle-stimulating hormone-releasing hormone
4. Luteinizing hormone-releasing hormone
5. Growth hormone-releasing hormone
6. Growth inhibiting hormone
7. Prolactin releasing hormone
8. Prolactin inhibiting hormone
9. Melanocyte stimulating hormone releasing hormone
10. Melanocyte stimulating hormone-inhibiting hormone.

 

(b) Pituitary:- Different hormones are secreted by different regions of the pituitary gland. The anterior lobe of the pituitary gland secretes the following hormones:

1. Follicle stimulating hormone
2. Luteinizing hormone
3. Thyroid stimulating hormone
4. Adrenocorticotropic hormone
5. Somatotrophic or Growth hormone
6. Prolactin hormone or Luteotropic hormone.

• Middle (intermediate) lobe of pituitary gland: Melanocyte stimulating hormone. Posterior lobe of pituitary:
1. Oxytocin
2. Vasopressin or antidiuretic hormone.

(c) Thyroid:- Thyroid secretes Thyroxine or tetraiodothyronine, Triiodothyronine and Calcitonin hormones.

(d) Parathyroid:-  Parathyroid gland secretes a single hormone called parathormone (PTH) or Collip’s hormones.

(e) Adrenal:-Adrenal glands have two regions, namely, outer adrenal cortex and inner adrenal medulla. Both these regions secrete different hormones.

Hormones of adrenal cortex are grouped into three categories:
1. Glucocorticoids, e.g., cortisol
2. Mineralocorticoids, e.g., aldosterone
3. Sexcorticoids e.g. testosterone.

Adrenal medulla secretes two hormones
1. Epinephrine (adrenaline)
2. Nor-epinephrine (nor-adrenaline).

(f) Pancreas:- Pancreas secretes Insulin, Glucagon and Somatostatin hormones.

(g) Testis:- Testis secretes androgens hormone.

(h) Ovary:- Ovary secretes Estrogens such as estradiol, Progesterone and Relaxin.

(i) Thymus:-Thymus secretes thymosin hormone.

(j) Atrium:- Atrium secretes atrial natriuretic factor (ANF).

(k) Kidney:- Kidney secretes Renin and Erythropoietin hormones.

(l) G-I Tract:-  G.I. tract secretes following hormones:

1. Gastrin

2. Secretin

3. Cholecystokinin

4. Enterocrinin

5. Duocrinin

6. Villikinin
