Answer:
The correct answer is hypophysis or pituitary.
Explanation:
The pituitary gland is at the size and shape of a pea and is also known as the master gland because it controls and stimulates the regulation of other endocrine glands. The pituitary gland is itself an endocrine gland which secretes its hormone directly in the blood.
Some hormones released by pituitary that stimulate other endocrine gland are adrenocorticotropic hormone (ACTH) which stimulate the adrenal gland to release cortisol. FSH and LH hormone that stimulate testes and ovary in male and female, Thyroid-stimulating hormone (TSH) which stimulate thyroid gland, etc. Therefore the right answer is pituitary.
