Hypothalamus & Pituitary Gland
The Hypothalamus is known as the “master” of the endocrine system and is the link between the nervous system and the endocrine system. Cells in the hypothalamus secrete 9 known hormones.
Thyrotropin Releasing Hormone Gonadotropin Releasing Hormone Growth Hormone Releasing Hormone Corticotrophin Releasing Hormone Prolactin Releasing Hormone Growth Hormone Inhibiting Hormone (somatostatin) Prolactin Inhibiting Hormone (Dopamine) Oxytocin Vasopressin (Anti-diuretic Hormone)
The Pituitary Gland is a prune-shaped structure that secretes 7 known hormones and together with the hypothalamus plays an important role in the regulation of virtually all aspects of growth, development, metabolism, and homeostasis. The pituitary gland is attached to the hypothalamus by a stalk called the infundibulum and has two functionally separate portions: the anterior lobe and the posterior lobe. It is received into a depression of the sphenoid bone, on the floor of the cranium called the sella turcica or hyposphyseal fossa.
