A master neuroendocrine gland at the base of the brain (housed in the sella turcica) that secretes hormones regulating growth, thyroid, adrenal, and gonadal function.
Secretes trophic hormones into the bloodstream to regulate growth, metabolism, stress response, and reproduction.
Hypophyseal fossa of the sella turcica of the sphenoid bone at the base of the brain.
Jump directly to connected anatomical structures to compare their locations, functions, and 3D relationships.
The pituitary gland and pineal body are closely integrated with the hypothalamus and diencephalon of the brain.
Endocrine glands are richly vascularized so hormones released into capillaries are rapidly distributed through the bloodstream.
The pancreas (modeled in the digestive layer) also performs vital endocrine roles by releasing insulin and glucagon into the blood.
