Examples include decreasing the heart rate or dilating the blood vessels.[AAO] PNS - parasympathetic MESH:D010275 EHDAA:4655 TAO:0001575 parasympathetic part of autonomic division of nervous system EFO:0000894 MA:0000223 EMAPA:17270 FMA:9907 The parasympathetic nervous system is one of the two divisions of the vertebrate autonomic nervous system. Parasympathetic nerves emerge cranially as pre ganglionic fibers from oculomotor, facial, glossopharyngeal and vagus and from the sacral region of the spinal cord. Most neurons are cholinergic and responses are mediated by muscarinic receptors. The parasympathetic system innervates, for example: salivary glands, thoracic and abdominal viscera, bladder and genitalia[GO]. uberon UMLS:C1305770 Wikipedia:Parasympathetic_nervous_system pars parasympathica divisionis autonomici systematis nervosi GAID:708 MIAA:0000101 AAO:0010488 In mammals, the autonomic nervous system is divided into two contrasting, antagonistic systems of control over visceral activity: the sympathetic system and the parasympathetic system (reference 1); In general, the teleosts may be considered phylogenetically the first class of vertebrates in which the heart is regulated by both sympathetic and parasympathetic neural pathways (reference 2).[well established][VHOG] VHOG:0000755 autonomic nervous system structure with developmental contribution from neural crest organ system subdivision
