Answers
Answer:
The hormones secreted by the following are:
(a) Hypothalamus- thyrotropin releasing hormone (TRH), Corticotropin releasing hormone (CRH), gonadotropin-releasing hormone (GnRH), growth hormonereleasing hormone (GHRH), somatostatin, dopamine, follistatin, Melanocyte-inhibiting factor (melanostatin), etc.
(b) Pituitary- Hormones secreted by the anterior pituitary are: Growth Hormone (GH), Thyroid Stimulating Hormone (TSH), Adenocorticotrophic hormone (ACTH), Prolactin (PRL), Follicle Stimulating Hormone (FSH) and Luteinising Hormone (LH). Hormones secreted by the posterior pituitary are: Oxytocin, Antidiuretic hormone (ADH)
(c) Thyroid - T3 (tri-iodothyronine), T4 (thyroxine) and calcitonin
(d) Parathyroid- Parathyroid hormone (PTH)
(e) Adrenal- Adrenal cortex secretes: glucocorticids, mineralocorticoids and sex hormones (androgens). Adrenal medulla secretes: Adrenaline (epinephrine) and Nor-Adrenaline (nor-epinephrine)
(f) Pancreas- Insulina and glucagon
(g) Testis- Inhibin
(h) Ovary- Inhibin
(i) Thymus- Thymosin
(j) Atrium- Atrial natriuretic peptide (ANP)
(k) Kidney- Erythropoietin
(i) G-I Tract- Gastrin, Secretin, Cholecystokinin
