Document Summary

Module 1: functionality of the nervous system: explain the integrations and operations of the nervous system. Nutrition is about science & biological processes. Ex. eating: when anticipate eating our mouth waters & preps for ingestion (parasympathetic mode- thinking of taking in things from outside to bring them in) Ex. public speaking: mouth gets dry bc in a threatening situation the sympathetic system is activated and the mouth gets dry from decreased salivary flow. Sympathetic & parasympathetic similarities: both come directly from spinal cord & both have at least one synapse: ganglion parasympathetic are located very closely in the organ, noradrenaline released at the end organ. Can learn to control parasympathetic system (i. e. an actor producing fake tears: gang. Sympathetic are located all along the spinal cord and interconnected: acetylcholine released at the end organ, acts only on the end organ to produce its effects, ca(cid:374)"t (cid:272)o(cid:374)t(cid:396)ol any pa(cid:396)t of sy(cid:373)patheti(cid:272) syste(cid:373) th(cid:396)u lea(cid:396)(cid:374)i(cid:374)g o(cid:396) (cid:373)ental action.
