Nerve Cells Flashcards
1
Q
myelin sheath
A
speed up conduction by insulating the nerve
2
Q
schwann cells
A
make myelin sheath in PNS
3
Q
oligodendrocytes
A
makes myelin sheath around CNS
4
Q
Axodendritic synapse
A
axon terminal of one neuron to dendrite of another neuron
5
Q
Axosomatic synpase
A
axon terminal of one neuron to cell body of another neuron
6
Q
Neurotransmitter molecules
A
acetylcholine norepinephrine dopamine serotonin histamine ATP
7
Q
resting potential
A
-70 mV
8
Q
Excitatory synapse
A
receptor binding causes postsynaptic potential to be more positive (depolarization)
9
Q
Inhibitory synapse
A
receptor binding causes postsynaptic potential to be more negative (hyperpolarization)
