Question
Write a short note.
Pituitary gland
Solution
The pituitary gland or master gland is located at the base of the brain. It consists of the anterior lobe and posterior lobe. The anterior lobe secretes growth hormone (which helps in bodily growth), ACTH (which controls secretion of adrenal glands), and prolactin (for the secretion of breast milk). If there is hypersecretion of growth hormone it results in gigantism while under the section of growth hormone results in dwarfism.
The posterior lobe of the pituitary secretes
- Oxytocin which related with feelings of pleasure.
- Antidiuretic hormone (ADH) which is responsible for reabsorption of water by the kidneys.
- Pituitrin which affects the functioning of smooth muscles.
- T.T.H (which controls the secretion by thyroid glands).
