Neuron and its actions

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

NGSS.MS-LS1-8

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

A chemical produced by neurons that carries messages to other neurons

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

When a neuron is at REST,

• the inside of the neuron is negatively charged compared to the outside.

• the inside of the neuron is positively charged compared to the outside.

• there is no charge difference established

• none of these is true

An electrical impulse within a single neuron is called a

• synapse

• membrane potential

• action potential

• cell body

What maintains the resting membrane potential in a neuron?

• sodium-potassium pumps

• sodium channels

• potassium channels

• gravity
