Question

Name the endocrine gland which secretes growth hormone. What will be effect of the following on a person, (i) Deficiency of growth hormone. (ii) Excess secretion of growth hormone.

Answer 1

The answer of this question is Pituitary Gland.

As the deficiency of a pituitary gland leads to dwarf and the excess of the pituitary gland can lead the individual to gigantism.

So the right answer is pituitary gland.

It should be under the limits, not to be much high and not to be much lower than the normal limits.

Answer 2

Here is your answer

••••••••••••••••••••••••••••••••••••••••••••••

- The endocrine gland which secrets growth hormone is PITUITARY GLAND.


- Pituitary Gland is also known as Master Gland. It is situated below the Hypothalamus. It has two lobes -


1. Anterior Lobe or Adenohypophysis - It secrets following hormones -

✓ Growth Hormone (GH) / Somatotrophic (STH).

✓ TSH

✓ ACTH

✓ FSH

✓ LH / ICSH

✓ PROLACTIN

✓ MSH


2. Posterior Lobe or Neurohypophysis - It secrets following hormones -

✓ ADH or Vasopressin

✓ Oxytocin


Now let's talk about GROWTH HORMONE -


As we mentioned earlier it secrets from adenohypophysis of pituitary gland which shows major effect on Growth and Metabolism also. It activates bone elongation and helps increase the number of cells through mitosis. It also stimulates growth of muscle and cartilage.

It helps in fat catabolism, protein anabolism and decreases glucose intake in the cell, therefore also known as Diabetogenic Hormone.


- It's hyposecretion causes dwarfism. When dwarfism caused by pituitary defect then it is termed as Ateliosis.


- It's hypersecretion causes -

(a.) hypersecretion in childhood - Gigantism. (characterised by long bone of legs and hand, increased height and imbalanced body.)

(b.) hypersecretion in adult - Acromegaly. (characterized by disfigurement, excess enlargement of facial bones, vertebral column and forelimbs.)
