Document Summary

Sensaion: process of our sensory system gathering informaion about our surrounding through the transformaion of chemical, light and sound energy into electrical aciviies into our brain. Senses go through transducion process: conversion of physical energy into electrical potenials. The receptor cells develop electrical potenials to response to physical simuli. Smell/taste=chemical h = color dness=brightness bre=color saturaion frequency=pitc amplitude=lou complexity=im receptors varies it"s reacion to simuli that difers quanitaively and qualitaively. 5 senses: vision, auditory, gustaion, olfacion, and somatosenses. somatosenses: bodily senses. ^skin senses, kinaestheic senses (posiion of internal muscles and organs and any sensory informaion), vesibular senses (balance and acceleraion, originated in inner ear) Doctrine of speciic nerve energies: every sensory domain has an adequate simulus, meaning the sensory receptors are uniquely sensiive to paricular types of physical energy (ex. eye-light, skin-mechanical pressure) Senses have receptor cells: specialized neurons that transducer physical energy into electrical signals.
