The part of brain which is known as master of master gland A) Hypothalamus B) Pituitary gland C) Cerebrum D) Cerebellum
Hint: It is a part of diencephalon. It maintains homeostasis and also acts as a thermoregulatory centre.
Complete answer: To answer this question, first, we need to know about the parts of the brain along with their functions. The brain is an organ composed of a large mass of nerve tissue that is protected inside the skull. The brain anatomy is complicated because of its complex structure and function. It functions as a control centre by interpreting, receiving, and directing sensory information throughout the body.
Now, let us find the solution from the given options- >Hypothalamus is the brain part controlling the endocrine system. The pituitary gland hanging from the hypothalamus by a thin stalk is called the body's master gland because it regulates endocrine gland activity. And the hypothalamus is a part of the lower middle brain which tells the pituitary gland when hormones should be released. Thus, the hypothalamus gland is called the master gland as it directs other organs and endocrine glands to either inhibit or stimulate the production of hormones. >The pituitary gland is a small pea-shaped gland, which is attached by a stalk-like structure to the hypothalamus. It secretes four tropic hormones (FSH, ACTH, LH, and TSH) which stimulate hormone synthesis and/or secretion from its target endocrine glands. Hence the pituitary gland is known as the master gland. The hypothalamus controls hormone production from the pituitary gland. >The cerebrum is the core of the human brain. It is responsible for our voluntary functions and processes our sense organs knowledge. This area is responsible for high functions in the brain such as learning, thinking, and memory. It is the uppermost region of the central nervous system. >The cerebellum is the area behind the brainstem, at the back and bottom of the brain. The cerebellum has many functions related to movement and coordination. It is known as a ‘little brain’ which mainly controls movement and balance. Also, it can play a role in cognitive functions such as language and attention.
Thus, the right answer is option A i.e., hypothalamus.
Note: The hypothalamus is an anterior and inferior diencephalon structure of the brain located at the thalamus. The hypothalamus is related anatomically and functionally to the pituitary gland.
