a)
b) - Answers Pacinian corpuscle, Ruffini's ending
two point discrimination is the ability to distinguish the: - Answers separation of two
simultaneous pinpricks on the skin
two point discrimination depends on the _________ of mechanoreceptors in the skin, and the
________ of their receptive fields. - Answers density, size
In two-point discrimination, bigger receptive fields indicate that it is _________ to discriminate,
and smaller being ________ to discriminate. - Answers harder, easier
sensory adaptation is the __________ sensitivity as a consequence of constant stimulation. -
Answers diminished (sensitivity)
In sensory adaptation, stimulus intensity in encoded by the _______-_______ of the receptor. -
, Answers firing rate
firing rate describes the rate at which a neuron produces _______-________ - Answers action
potentials
(usually expressed in terms of spikes per second)
adaptation rate describes: - Answers how quickly a receptor ceases to fire with ongoing input
slowly adapting fibers _______-_______ as long as stimulus is present. - Answers keep responding
_______-______ fibers keep responding as long as the stimulus is present, meaning they are
sensitive to the *duration* of a stimulus.
~think sustained touch, stretching mechanism - Answers slowly adapting (fibers)
rapidly adapting fibers respond to stimulation with a _______ of _______ at the beginning and end
of stimulation. - Answers burst of firing
________ ________ fibers respond to stimulation with a burst of firing at the beginning and end of
stimulation. - Answers rapidly adapting (fibers)
_________-_________ are an example of rapidly adapting fibers that fire in bursts at the beginning
& end of stimulation. These are sensitive to the ___________ in stimulus.
~Think *vibration* (time-varying pressure changes) - Answers Pacinian corpuscles, changes
rapid adaption of pacinian corpuscles results from? - Answers the capsule that makes the
corpuscle sensitive to on/off activity & insensitive to sustained activity.
Pacinian corpuscles do not respond to _________ pressure due to the capsules *slipping* past
each other dissipating the deformation of the nerve ending. - Answers sustained (pressure)
Pacinian corpuscles are sensitive to the _________ and _________ of the stimulus. - Answers start,
stop
Mechanotransduction occur with: - Answers mechanosensitive ion channels
Mechanotransduction is the conversion of mechanical stimulus to an __________ or _________
signal. Different channels tend to respond to different forces. - Answers electrical (or) chemical
signal
