Nervous system quiz

The basic unit of structure and function in the nervous system is a nerve cell. Nerve cells are also called-

• Osteocytes

• Dendrites

• Neurons

• Spinal Cords

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

• axon

• dendrite

• myelin

• Node of Ranvier

The part of the neuron that receives messages from adjacent neurons

• axon

• axon terminal

• dendrite

• neuron

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 one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin

What do the motor neurons do?

• carry messages from the brain and spinal cord to muscles and glands
