Thermoreception Flashcards
what is thermoreceotion
detection of no noxious temp changes
what is themrorceeption imp for
sensory warm cold sensation nd reflexes
devveoped for protection of mouth
flavour expeirnece
why is the mouth “cold bias’
5-10x more cold spots than hot spots
what do hot an cold temperatures stimulate in the teeth
cold –> may be +/- pain
hot –> pain
what are th peripheral nerves of thermoreception
free nerve endings
A beta and C fibres
what are the central pathways of themroreception
1st synapse in V nucleus caudal
minimal modification at first synapse
what are the peripheral nerves of niciception
free nerve endings
A beta nd C fibres
what are the central pathways of nocicipetion
1st syn in V nucleus caudal +/- oralis
significant modification at first syn
what are the static rpooeprties of themrorceeptos
steady firing with constant temp
what are the dynamic properties of themroreceptors
warm recep
- warming - inc frequency AP
- cooling - transient inhibition
cold recep
- warming - transient inhibition
- cooling - inc frequency AP
what istranduction for thermorceteptin
temp causes mem perm change - receptor
