Nervous System Lesson

Multiple Choice

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

• axon 
• dendrite
• axon terminal
• gene

Multiple Choice

This releases neurotransmitters which are sent into the synaptic cleft for receptors on the dendrite to taste

• axon
• axon terminal
• gene
• neuron

Multiple Choice

A network of branches coming from individual cells.  They carry information and electrical signals in the brain and nervous system

• axon
• axon terminal
• dendrite
• neuron

Multiple Choice

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

Multiple Choice

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
