Intro to Neuroscience - Exam 2
Terms in this set (473)
True or False: Receptor cells True
are like filters, converting key
stimuli into electrical signals
What is the end product of Action potentials
sensory receptors?
A physical event that triggers a Stimulus
sensory response
The concept that each nerve Labeled lines
input to the brain reports only
a particular type of information
A local change in the resting Generator potential
potential of a receptor cell in
response to stimuli, which may
initiate an action potential
What other type of signal does EPSPs
a generator potential
resemble?

The process in which a Sensory transduction
receptor cell converts the
energy in a stimulus into a
change in the electrical
potential across its membrane
A skin receptor cell type that Pacinian (lamellated) corpuscle
detects vibration & pressure
Where in the skin are pacinian The innermost layer
corpuscles located?
What is the absolute threshold 200+ cycles per second
of pacinian corpuscle
detection?
How are sensory nerve ending The stretching of nerve ending membranes, causing
generator potentials created? mechanically gated Na+ channels to pop open
True or False: The strength of a True
stimulus is proportional to the
amplitude of the generator
potential
True or False: Sensory systems True
often shift away from accurate
portrayal
The stimulus intensity adequate Threshold
to trigger an action potential in
a sensory cell

Which sensory receptor Meissner's corpuscles
responds to change in stimuli?
Meissner's (tactile) corpuscles The forms of objects we touch
and Merkel's discs both
mediate our ability to perceive
what?
A skin receptor cell type that Merkel's discs
detects light touch, responding
especially to edges and
isolated points on a surface
A skin receptor cell type that Ruffini corpuscles
detects stretching of the skin
An axon that terminates in the Free nerve endings
skin and has no specialized cell
associated with it; detects
pain/temperature changes
True or False: As the strength True
of a stimulus increases,
additional sensory neurons
sensitive to higher intensities
are "recruited"
The stimulus region and Receptive field
features that affect the activity
of a cell in a sensory system
The progressive loss of Sensory adaptation
receptor response as
stimulation
