Electrical and Chemical Communication in Neuron

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

• axon 
• dendrite
• axon terminal
• gene

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

• axon
• axon terminal
• gene
• neuron

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

A nerve cell that is the basic working unit of the brain and nervous system which processes and transmits information

• axon
• neuron
• dendrite
• neurotransmitter

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

How many nerve cells does the brain contain?

• 100 million
• 86 billion
• 86 million 
• 100 billion

What is the brain made of?

• Nerve tissue
• Brain tissue
• Cortex tissue 
• Stem tissue
