somatic and telereceptors
Term
what is an example of unconscious receptor?
Definition
proprioceptors
Term
what are unconscious receptors also called?
Definition
enteroreceptors
Term
what are unconscious receptors also called?

enteroreceptors
Term
what is the function of generator potentials?
Definition
trigger action potentials
Term
what is the requirement change for depolarization?
Definition
increase of 10mv
Term
what do generator potentials do as they get further from the stimulus
Definition
decay/decrease
Term
what can shut off recognition of generator potentials?
Definition
higher responses
Term
what does sensory processing depend on?
Definition

intensity of sensation

detectability

transduction

Term
what are the physiologic categories for receptors?
Definition
slowly adapting and rapidly adapting
Term
what are the slowly adapting receptors and what do they respond to?
Definition

free nerve endings, merkels disks, ruffini's endings

these all respond to unchanging stimuli

Term
what are the rapidly adapting receptors and what do they respond to?
Definition

meissner's and pacinician's corpuscles

they respond to changing stimuli

Term
what is adaptation?
Definition
decrease in receptor sensitivity during course of maintained stimulus
Term
what is a decrease in receptor sensitivity during course of maintained stimulus?
Definition
adapation
Term
name the functional receptor types
