===Neuropeptides===
'''Vasoactive intestinal peptide (VIP)''' plays a role within the intestines and acts to greatly increase the secretion of water and electrolytes. VIP also causes dilation of the smooth muscle within the peripheral smooth muscles and inhibits [[[Gut_Endocrine_Function_-_Anatomy_%26_Physiology|gastrin-stimulated]] gastric acid secretion. The neuropeptide '''vasopressin''' is responsible for metabolism and maintainence of the metabolic rate. The overall affect of VIP is to increase gastric motility. '''Somatostatin''' inhibits the production of other hormones.

'''Substance P''' is involved in the transmission of pain from peripheral receptors to the central nervous system. It acts to increase the sensation, and therefore the conciousness, of pain and is released when [[Pain|nociceptors]] are activated. '''Enkaphalin''' acts to inhibit the release of substance P therefore acting to diminish the sensation of pain.

'''Somatostatin''' inhibits the production of other hormones.
