Nerve Cell Communication

An impulse (action potential) could be described as area of _________ charges that travel over the outside of the neuron

Negative

Which part of a neuron receives the chemical message?

Receptor Protein on the receiving neurons

Nucleus

The part of the neuron that controls the life activities of the neuron

Axon

The part where the neuron conducts electrical impulses over long distances

Terminal Branches

The part where the neuron sends chemical signals o other neurons

What are two names for the electrical signal that is conducted along a neuron called?

Impulse or action potential

Why cant an impulse pass directly from one nerve cell to another?

It cant jump the synapse

Dendrite

Part where the neuron sends chemical signals from other neurons and the neuron that has receptor proteins attached to the cell membrane

The outside of the neuron that is not conducting an impulse will have a ___________ charge

Positive

Neurotransmitters

The chemical signal molecule produced by a neuron

Impulse

The electrical signal that is conducted by a neuron.

Synapse

The gap between two neurons

Myelin Sheath

The structure forms an insulation covering for axons and speeds up impulse conduction along an axon

Vesicle

The structure in a neuron stores chemical signal molecules

Which part of a neuron releases the chemical message?

Vesicles in the terminal branch

What causes the sending nerve cell to release a chemical message into the synapse?

When the impulse reaches the terminal branches of a neuron, it triggers the release of neurotransmitter molecules from the vesicles.
