Sensation and the Chemical Senses Flashcards
what is transduction also known as?
graded potential
how is propagation done?
via labeled line
what is receptor modality
what the type of stimulus is
what does the modality stimulus follow?
the labelled line
how do modality stimulus travel?
from sensory receptor to the cerebral cortex, from there it depends on the brain region stimulated
what allows a stimulus to dectect location?
receptive fields
how is location percieved bas on brain region?
sensory homonculus
what is the two point discrimmination based on
the relative number of receptive fiels on skin area
What does the intesity receptor proerty detect?
how strong a stimulus is
how is the intensity receptor measured?
higher rate of action potentials, multiple neurons, and variable sensitivity(which ones)
what provide info on onset and or intesity of stilulus followed by quick sensory adaption?
phasic receptors
what are examples of phasic receptors?
thermoreceptors, tactile receptors, taste and smell
what are the receptors called that have little to no adaptation?
tonic receptors
what are examples of tonic receptors? p
pain, muscle spindles, proprioceptors
what type of stimulus do thermoreceptors have?
kinetic
