Correct option is A
The correct answer is (a) Pituitary Gland
Explanation:
. Growth hormone (GH), also known as somatotropin, is secreted by the anterior pituitary gland.
. It plays a crucial role in growth of bones and muscles during childhood and adolescence.
. GH regulates cell growth, cell reproduction and tissue regeneration.
. Deficiency of GH in childhood causes dwarfism.
. Excess secretion leads to gigantism in children and acromegaly in adults.
Information Booster:
. Secretion of growth hormone is regulated by hypothalamic hormones—GHRH stimulates and somatostatin inhibits it.
. The pituitary gland is known as the “master gland” as it controls other endocrine glands.
