2. Nervous System Flashcards
1
Q
spatial summation
A
multiple dendrites receive signals at the same time
2
Q
temporal summation
A
adds up the effects of signals that are received by a single dendrite over time
3
Q
resting potential
A
electrical potential (voltage)
more negative inside and more positive outside
the potential for adding positivity
4
Q
how does the concentration gradient of Na+/K+ stay out of equilibrium?
A
the sodium potassium pump moves 3 Na+ out of cell and 2 K+ into cell
5
Q
resting membrane potential
A
-70mV
6
Q
what affects resting membrane potential?
A
the diffusion of K+ out of the cell
they bring negativity with them
many more K+ channels open than Na+ channels
