Answer:
With respect to the anterior pituitary gland, it is true that it is often referred as the "master gland" of the endocrine system (option C).
Step-by-step explanation:
The pituitary gland —also called hypophysis— divided into two parts, an anterior part called the adenohypophysis and a posterior part called the neurohypophysis.
The adenohypophysis or anterior pituitary gland is in charge of the secretion of hormones that serve to regulate the hormonal secretion of other glands, such as the thyroid, the suprarenal glands and the gonads. This is the reason why it is considered and often referred as the "master gland" of the endocrine system.
The neurohypophysis depends on the control of the hypothalamus and the neurotransmitters that this structure sends to the pituitary, releasing hormones whose effect is direct on the target organ.
The other options are not correct because:
A. Anterior pituitary does not release hormones made by the neurons in the hypothalamus.
B. Adenohypophysis has hormone-producing cells.
D. The anterior pituitary is not regulated by the hypothalamus and is considered part of the endocrine system.
