उत्तर
This statement is false.
Explanation:
Adrenaline is secreted by the adrenal gland because adrenaline (epinephrine) is produced by the adrenal medulla, which is the inner part of the adrenal glands located on top of the kidneys. It is responsible for the “fight-or-flight” response. The pituitary gland, on the other hand, is known as the “master gland” and secretes hormones such as growth hormone, TSH, and ACTH that regulate other glands and bodily processes.
