Gigantism and Dwarfism are the diseases related to
The correct option is B Growth hormone of adenohypophysis
The correct option is B:
Explanation of the correct option:
- The anterior and the intermediate lobe of the pituitary gland make Adenohypophysis.
- The anterior portion is also called pars distalis and secretes tropic hormones. Tropic hormones stimulate the other endocrine glands to release their hormones.
- The growth hormone thus secreted stimulates somatotropic cells present in the anterior lobe of the pituitary gland and somatotropin is released.
- Over-production of somatotropin during childhood leads to gigantism and under-production of the hormone leads to dwarfism.
Explanation of the incorrect options:
Option A:
Prolactin is responsible for regulating the growth of the mammary glands and milk production.
Option C:
The Luteinizing hormone of the pituitary gland is responsible for the synthesis and secretion of androgens from the testis in males, and for inducing ovulation of Graafian follicles.
Option D:
The thyroid gland secretes thyroxine, triiodothyronine, and calcitonin. The disorders caused by abnormalities in thyroid hormones may cause hypothyroidism or hyperthyroidism.
Final Answer: Gigantism and Dwarfism are the diseases related to the growth hormone of the adenohypophysis.
