Sensory Parhways Flashcards
if you close eyes and rub them you may experience patterns of light stimulated by the pressure.
T/F
T
The area monitored by a single receptor is called its_____
receptive field.
If the receptive field is large, it will be____ to pinpoint to exact point stimulated.
difficult
The body surface has____ receptive fields while the tongue has very____ receptive fields.
large
small
receptor potential that is great enough to create an action potential is called a_____ potential.
generator
For special senses
The receptor potential would occur in the _____and the generator potential would occur in the_____
receptor cell
sensory neuron.
Information travels from specific receptors to specific regions of the brain along pathways called____
labeled lines.
Tonic sensory Receptors
•Tonic receptors are always___.
•There is always a “_____” stimulus.
•Changes in stimulus change the rate (frequency) of the action potentials generated.
Phasic Receptors
•Phasic receptors are___ but become____ for a____ period of time whenever changes occur in the conditions they are monitoring.
active; background
inactive; active; short
Phasic and tonic receptors
Which are rapid /slow adapting
Phasic-rapid
Tonic-slow
In peripheral adaptation, the____ reduces and amount of information that reaches the CNS.
In central adaptation, the ______restricts the amount of information that arrives at the cerebral cortex.
PNS
sub conscious level
Proprioceptors can be somatic or visceral receptors
T/F
F
Only somatic
Only about __% of the information picked up by the general senses gets passed on to the cerebral cortex and conscious awareness.
