Neuron Structure Flashcards
1
Q
Soma
A
Cell body containing nucleus and controls all functions of the cell
2
Q
Dendrites
A
Bring information to neuron
3
Q
Axon
A
Carries nerve impulses away from soma
4
Q
Axon Hillock
A
Axon arises from cell body
5
Q
Axon Terminal
A
Make contact with other neurons
6
Q
Myelin Sheath
A
Insulating layer around axons that increase speed of nerve impulses
7
Q
Nodes of Ranvier
A
Space between myelin sheath where the Na and K pump is located – necessary for action potential to travel down axon
8
Q
Pre-synaptic terminal
A
End point of neuron that communicates with succeeding neuron
9
Q
Post-synaptic terminal
A
Receive action potential from neuron prior
10
Q
Synaptic cleft
A
Small gap between two communicating neurons
