What is the function of the nervous system?

• Transport nutrients around the body
• Send and receive messages to respond to a change in an organisms environment
• Brings oxygen into the body
• Moves body parts

The long, fibre like part of a neuron that transmits neural information away from the soma to other neurons or cells is known as the

• axon

• dendrute

• axon terminal

• synapses

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

• Dendrite

• Myelin Sheath

• Node of Ranvier

This part of the neuron receives chemical messages from the neurotransmitters of other neurons

• Axon terminal

• Myelin sheath

• Cell body

• Dendrites

This part of the neuron stores then releases neurotransmitters into the synapse

• Axon

• Myelin sheath

• Axon terminal

• Dendrite

The correct direction of the neural impulse within the neuron:

• Axon terminal to dendrite

• Cell body to axon

• Dendrite to axon terminal

• Axon terminal to cell body

The part of the neuron that brings information to the cell body is called the

• dendrite

• axon

• nucleus

• node of ranvier
