==Hypothalamus==
==Hypothalamus==
+The hypothalamus is a small area in the ventral diencephalon of the [[Forebrain - Anatomy & Physiology|forebrain]], in the floor of the third ventricle, and is a functional link between the [[Nervous and Special Senses - Anatomy & Physiology#Nervous System|nervous]] and [[Endocrine System Overview - Anatomy & Physiology|endocrine]] systems.
+
+The hypothalamus controls most of the [[Endocrine System Overview - Anatomy & Physiology|endocrine glands]] within the body, largely through stimulation of the [[Pituitary Gland - Anatomy & Physiology|Pituitary Gland]] by secretion of [[Hormones - Anatomy & Physiology#Classifications of Hormones|neurohormones]]. It is a vital regulator of homeostasis, including [[Thermoregulation - Anatomy & Physiology| Thermoregulation]]. Further information on the physiology of the hypothalamus can be found [[[Hypothalamus - Anatomy & Physiology|here]].

==Pituitary Gland==
==Pituitary Gland==
The pituitary gland, or '''hypophysis''' is an elongated appendage of the brain lying within a bony cavity of the [[Skull and Facial Muscles - Anatomy & Physiology#Sphenoid Bone (os sphenoidale)|sphenoid bone]] in the base of the skull - the '''Sella Turcica'''. The hypophysis is suspended ventral to the the [[Hypothalamus - Anatomy & Physiology|hypothalamus]] by a thin '''infundibular stalk'''. It lies between the more rostral '''optic chiasma''', and the more caudal '''mammillary bodies''', separated from the brain by a fold of dura mater known as the '''diaphragma sellae'''. The gland is divided into '''anterior and posterior''', with different embryological origins reflecting a difference in function.
