A
The cerebellum controls the pituitary gland by sending electrical signals.
B
The medulla oblongata controls the pituitary gland through direct neural connections.
C
The thalamus controls the pituitary gland by altering blood flow.
D
The hypothalamus controls the pituitary gland by releasing hormones that regulate its function.
Verified step by step guidance1
Identify the main function of the pituitary gland, which is to secrete hormones that regulate various physiological processes in the body.
Understand that the hypothalamus is a region of the brain that plays a crucial role in maintaining homeostasis by linking the nervous system to the endocrine system via the pituitary gland.
Recognize that the hypothalamus controls the pituitary gland by releasing specific hormones known as releasing and inhibiting hormones.
These hormones are transported to the pituitary gland through a specialized blood vessel system called the hypothalamic-pituitary portal system.
Once these hormones reach the pituitary gland, they stimulate or inhibit the release of hormones from the pituitary, thereby regulating its function and influencing various bodily processes.
