ANATOMY

Detailed explanation-1: -The pituitary and adrenal gland can be controlled by the direct influence of the nervous system. The posterior pituitary is directly controlled by the hypothalamus of the brain and the adrenal medulla responds to sympathetic nervous system stimulation.

Detailed explanation-2: -The gland lies well protected in a small bony cavity of the skull, level with the eyes, and roughly in the middle of the head. Together with the hypothalamus – which belongs to a part of the brain known as the diencephalon – the pituitary gland controls the involuntary (vegetative) nervous system.

Detailed explanation-3: -The hypothalamus produces corticotropin-releasing hormone (CRH) that stimulates the pituitary gland to secrete adrenocorticotropin hormone (ACTH). ACTH then stimulates the adrenal glands to make and release cortisol hormones into the blood.

Detailed explanation-4: -Your pituitary gland is connected to your hypothalamus through a stalk of blood vessels and nerves (the pituitary stalk). Through that stalk, your hypothalamus communicates with the anterior pituitary lobe via hormones and the posterior lobe through nerve impulses.
