1.

The long, fiber like part of a neuron which the cell sends information to receiving neurons

a)

axon

b)

dendrite

c)

myelin

d)

Node of Ranvier

2.

This releases neurotransmitters which are sent into the synaptic cleft for receptors on the post-synaptic neuron to receive

a)

dendrite

b)

axon terminal

c)

Scwann cells

d)

myelin

3.

The part of the neuron that receives messages from adjacent neurons

a)

axon

b)

axon terminal

c)

dendrite

d)

neuron

4.
