What is Sensory system?
[[File:Eye iris.jpg|thumb|An eye turns [[photon]]s into nerve impulses: the brain's [[visual cortex]] turns the impulses into information which the brain can handle. [[wikt:subjective|Subjective]]ly, we feel we see the world 'directly'. Actually, the brain has constructed what we see from data given to it by our eyes.]] The '''sensory system''' is the way [[animal]]s find out about their nearby [[environment]] and their [[Body|bodies]]. To do this they have special [[device]]s for collecting [[Information|data]] called [[sense organ]]s. The sense organs act as [[Transduction (physiology)|transducers]]: they turn [[energy]] from the outside or inside of the body into [[nerve]] [[Signal (biology)|signals]]. The signals are then very rapidly processed by the [[brain]]. The whole arrangement is the sensory system. It is usual to say the sensory system has five senses: # [[Hearing]] is the sense of [[sound]]. [[Ear]]s [[hear]] [[sound]]s. # [[Sight]] is the sense of [[see]]ing. [[Eye]]s see. # [[Touch]] is the sense of [[feeling]]. [[Sense organ]]s feel. # [[Taste]] is the sense of the [[flavor]]. [[Tongue]]s taste. # [[Olfaction|Smell]] is the sense of [[scent|scent or odor]]. [[Nose]]s smell. There are other senses. For example, we have a sense of [[equilibrioception]] which checks our [[balance]], and [[proprioception]] which is the sense of the relative position of one's own parts of the body and strength of effort being employed in movement.<ref>{{Cite journal|last1=Proske|first1=Uwe|last2=Gandevia|first2=Simon C.|date=2018-06-18|title=Kinesthetic Senses|url=http://dx.doi.org/10.1002/cphy.c170036|journal=Comprehensive Physiology|volume=8|issue=3|location=Hoboken, NJ, USA|publisher=John Wiley & Sons, Inc.|pages=1157–1183|doi=10.1002/cphy.c170036|pmid=29978899|isbn=9780470650714|s2cid=49704241}}</ref> Fishes have a sense system which no land animal has.<ref>Most [[amphibia]]n [[larvae]] have a similar system.</ref> It is called the [[lateral line]] system.
