review for exam 1 Flashcards
1
Q
___________ membrane resistance = current doesnt readily flow across membrane = forces current to spread internally which is path of least resistance
A
high
2
Q
the ability of the membrane to store charge (ions stored on each side of the membrane)
A
capacitance
3
Q
the more charge that is stored, _______ it takes to discharge = time constant increases = ___________ for depolarization
A
longer
longer
4
Q
increases membrane resistance and decreases capacitance
A
myelination
5
Q
current flows btw cells via gap junctions
A
electrical synapse
6
Q
gap btw presynaptic and postsynaptic =
A
synaptic cleft
7
Q
___________ causes a release of synaptic cleft
A
Ca2+
8
Q
___________ binds ligand gated channel on post synaptic cell leading to ___________
A
neurotransmittor
depolarization
hyperpolarization
9
Q
A
