The basic building block of the nervous system is called a:

• Hormone

• Neuron

• Synapse

• Receptor

Which part of the neuron carries messages away from the cell body?

• Axon

• Dendrite

• Synapse

• Vesicle

The gap between two neurons is called the:

• Myelin sheath

• Axon terminal

• Synapse

• Soma

Neurotransmitters are released from:

• Dendrites

• Vesicles in the axon terminal

• Receptors

• Synapses

Which of the following best describes a neurotransmitter?

• A hormone that circulates in the blood

• A chemical messenger that crosses the synapse

• A part of the axon

• An electrical impulse

When neurotransmitters cross the synapse, they attach to:

• Other neurotransmitters

• Vesicles

• Receptors on the next neuron

• Axons

An excitatory neurotransmitter makes the next neuron:

• Less likely to fire

• Stop firing permanently

• More likely to fire

• Unresponsive

An inhibitory neurotransmitter:

• Speeds up the signal

• Blocks or reduces the chance of firing

• Creates a new neuron

• Always causes mood changes

What is the purpose of reuptake?

• To recycle neurotransmitters back into the neuron

• To destroy neurons

• To create more synapses

• To generate electrical impulses

Electrical signals travel ______ the neuron, while chemical signals travel ______ neurons.

• Inside; between

• Between; inside

• Around; through

• Slowly; quickly
