1
Q
Areas of a neuron (6)
A
nucleus
dendrite
axon
myelin sheath
nodes of ranvier
terminal buttons
2
Q
Features of nucleus of a neuron (2)
A
control centre of cell
contains cell DNA
3
Q
Features of dendrite of a neuron
A
receives nerve impulse/signal from adjacent neurons
4
Q
Features of axon of a neuron
A
where electric signal passes along
5
Q
Features of myelin sheath of a neuron
A
insulates/protects axon from external influences
6
Q
Features of nodes of ranvier of a neuron
A
speed up transmission of impulse by forcing it to “jump”
7
Q
Features of terminal buttons of a nueron
A
send signals to adjacent cell
8
Q
Define an action potential
A
electric signal which travels down axon, allowing it to communicate with other neurons
9
Q
Define a neuron resting state
A
neuron is at rest with negative charge
