Question	Answer	Article
Describe the location of the hypothalamus.	The hypothalamus is in the ventral diencephalon in the floor of the third ventricle.	Link to Article
Name the 6 nuclei of the hypothalamus and their individual functions.	Paraventricular - Production of Oxytocin and ADH Supraoptic - Production of Oxytocin and ADH Suprachiasmatic - Circadian Rhythm and Biological Clock Lateral - Arousal Arcuate - Energy Mamillary - Wakefulness	Link to Article
Name the three things which the hypothalamus detects using direct receptors:	Termperature Osmolarity of the Blood Energy Balance	Link to Article
List the Hormones synthesised in the hypothalamus	ADH Oxytocin Thyrotropin Releasing Hormone (TRH) Growth Hormone Releasing Hormone (GH-RH) Gonadotrophin Releasing Hormone (GnRH) Corticotropin Releasing Hormone (CRH) Prolactin Releasing Hormone (PRL-RH) Growth Hormone Inhibiting Hormone aka Somatostatin (GH-IH) Gonadotrophin Inhibiting Hormone (GnIH) Dopamine (PRL-IH)	Link to Article
Locate the hypothalamus on this diagram:	See below	Link to Article
Describe what is meant by Negative Feedback with respect to the hypothalamus.	The hypothalamus releases hormones which cause a response from other organs. The response then feeds back to the hypothalamus to limit the production of it's original hormone. This is a self-limiting system enabling the hypothalamus to control homeostasis.	Link to Article
