Introduction to nervous system

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

• axon

• dendrite

• myelin

• Node of Ranvier

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

A chemical produced by neurons that carries messages to other neurons

• myelin sheath
• neurotransmitter
• axon
• axon terminal

The tiny gap between neurons where nerve impulses are sent from the neuron to the receiving cell.

• synapse

• axon terminal

• impulse

• myelin

Gaps between Schwann cells that increase the speed of the transmission of the signal down the neuron are called

• axon terminals

• dendrites

• myelin

• nodes of Ranvier

The basic structural unit of the nervous system:

• nerve

• neuron

• brain

• spinal cord
