_____ neurons carry messages away from the central nervous system and out to muscles or glands. The RED neuron in diagram.

• sensory

• motor

• central

How is a message delivered from the "sending" neuron to the "receiving" axon?

• sympathetic nerves

• hormones

• medulla oblongata

• neurotransmitters

Brain cells are called

• hemoglobin
• neurons
• brainpoppers
• alveoli

_______ is primarily an inhibitory transmitter

• GABA

• Serotonin

• Norepinephrine

• Dopamine

_______ plays a key role in Reward Pathways and is implicated in addictive disorders

• Acetylcholine

• Serotonin

• Dopamine

• GABA

Serotonin is a neurotransmitter that helps regulate:

• learning and memory
• pain and pleasure
• muscle movements
• sleep, moods/emotions

The somatic nervous system

• regulate visceral muscle response

• enable deliberate movement by the body

• controls fight-flight-freeze

• initiate the response of peripheral muscles

The role of an axon during transmission is to

• produce and release neurotransmitters.

• provide a barrier to other electrical impulses

• carry nerve impulses away from a cell’s body

• speed up electrochemical transmissions to adjoining neurons.
