Question

name the hormones secreted by the following endocrine glands and specify one function of each 1) thyroid 2)pituitiary 3) pancreas

Answer 1

a) Hypothalamus: Hormones secreted by the hypothalamus include:

(1) Releasing hormones: These hormones stimulate the secretions of the pituitary hormone. Examples of these hormones are:

(i) Gonadotrophin-releasing hormone

(ii) Thyrotrophin-releasing hormone

(iii) Somatotropin-releasing hormone

(iv) Adrenocorticotrophin-releasing hormone

(2) Inhibiting hormones: These hormones inhibit the secretions of the pituitary hormone. Examples of these hormones are:

(i) Somatostatin

(ii) Growth-inhibiting hormone

(iii) Melanocyte-inhibiting hormone

(b) Pituitary: The pituitary gland has two components i.e., adenohypophysis and neurohypophysis.



Hormones secreted by the adenohypophysis are:

(i) Growth hormone (GH)

(ii) Prolactin

(iii) Thyroid-stimulating hormone (TSH)

(iv) Adrenocorticotrophic hormone (ACTH)

(v) Luteinizing hormone (LH)

(vi) Follicle-stimulating hormone (FSH)

(vii) Melanocyte-stimulating hormone (MSH)

Hormones secreted by the neurohypophysis are:

(i) Oxytocin (Birth Harmone)

(ii) Vasopressin [Anti-diuretic Harmone(ADH)]

(c) Thyroid: The thyroid gland secretes three hormones namely, thyroxin, triiodothyronin, and calcitonin.

(d) Parathyroid: The parathyroid gland secretes a hormone known as the parathyroid hormone.(PTH)

(e) Adrenal: The adrenal gland is divided into two parts, the outer adrenal cortex and the inner adrenal medulla.

Hormones of adrenal cortex include the following:

(i) Mineralocorticoids: The hormone secreted is known as aldosterone.

(ii) Glucocorticoids: The hormone secreted is cortisol.

Hormones of adrenal medulla are adrenaline and nor-adrenalin
