1
Q
Most sensory receptors are stimulated only by…
A
a specific stimulus
2
Q
How does a specific stimulus produce a receptor potential
A
by enhancing Na+ influx into the receptor
3
Q
Initiation of a receptor potential
A
adequate stimulus -> could initiate an AP
4
Q
How does the receptor detect stimulus intensity
A
by generating receptor potentials having higher magnitudes
5
Q
The ability to localise the site of stimuli depends on…
A
connections between the receptor and sensory cortex
6
Q
One way in which IPSP differs from EPSP
A
IPSP moves membrane potential away from threshold
7
Q
An IPSP results from…
A
opening of K+ channels
8
Q
Define spatial summation
A
signals coming from multiple simultaneous inputs
9
Q
Define temporal summation
A
repeated inputs
