NS's, Neurons, & NT's

Which neurotransmitter eases pain and creates a sense of euphoria?

• Acetylcholine

• Dopamine

• Serotonin

• Endorphins

Stating that a "neural impulse of positively charged ions is fired" is one way to explain what term?

• Axon Terminal

• Action Potential

• Refractory Period

• Neurotransmitter

This chemical neurotransmitter affects mood, sleep, and appetite.

• Acetylcholine

• Dopamine

• Serotonin

• Endorphins

The all-or-none principle indicates:

• an individual only uses one hemisphere of their brain

• individuals either have 100 billion neurons or zero neurons

• all neurotransmitters must find a receptor site or none do

• the intensity of a neural impulse is the same regardless of the input

This component of the neuron helps speed up a neural transmission.

• Serotonin

• Axon

• Hippocampus

• Myelin Sheath

Schizophrenia is most closely linked with excess activity at receptor sites for the neurotransmitter.

• Acetylcholine

• Dopamine

• Serotonin

• Endorphins

When a neuron is "loaded up" and negatively charged, this is known as the:

• Resting Potential

• Antagonistic Potential

• Refractory Potential

• Agonistic Potential

The concept of "rest and digest" is connected with what division of the nervous system?

• Parasympathetic Nervous System

• Central Nervous System

• Axon Terminal Nervous System

• Sympathetic Nervous System
