 a nerve cell; the basic building block of the nervous system. 

• axon

• dendrites

• neuron

• myelin sheath

• axon

• dendrites

• neuron

• myelin sheath

the neuron extension that passes messages through its branches to other neurons or to muscles or glands.

• neuron

• myelin sheath

• dendrites

• axon

 a fatty tissue layer segmentally encasing the axons of some neurons; enables vastly greater transmission speed as neural impulses hop from one sausage-like node to the next.

• neuron

• myelin sheath

• axon

• dendrites

chemical messengers that cross the synaptic gaps between neurons. When

released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
