Neuron Structure

Question 1

Soma

Answer 1

Cell body containing nucleus and controls all functions of the cell

Question 2

Dendrites

Answer 2

Bring information to neuron

Question 3

Axon

Answer 3

Carries nerve impulses away from soma

Question 4

Axon Hillock

Answer 4

Axon arises from cell body

Question 5

Axon Terminal

Answer 5

Make contact with other neurons

Question 6

Myelin Sheath

Answer 6

Insulating layer around axons that increase speed of nerve impulses

Question 7

Nodes of Ranvier

Answer 7

Space between myelin sheath where the Na and K pump is located – necessary for action potential to travel down axon

Question 8

Pre-synaptic terminal

Answer 8

End point of neuron that communicates with succeeding neuron

Question 9

Post-synaptic terminal

Answer 9

Receive action potential from neuron prior

Question 10

Synaptic cleft

Answer 10

Small gap between two communicating neurons
