Chapter 2 Psychology: The Nervous System

The resting potential of the neuron is about ___________. - +30 millivolts - 0 millivolts - +70 millivolts - -70 millivolts

-70 millivolts

What are the neurotransmitter responsible for producing muscle contraction? - Serotonin - Endorphins - Acetylcholine - GABA

Acetylcholine

Which part of the neuron transmits information away from the cell body? - Myelin - Dendrites - Axons - Axon terminal

Axons

Which part of a neuron receives information from other neurons? - Axon - Myelin - Dendrite - Nucleus

Dendrite

Which neurotransmitter is involved in the regulation of movement and the ability to experience pleasure? - Dopamine - Norepinephrine - Serotonin - Acetylcholine

Dopamine

What is the function of myelin sheaths? - They provide nutrients to the neuron. - They allow for slower transmission of the neural impulse. - They allow for faster transmission of the neural impulse. - They store neurotransmitters

They allow for faster transmission of the neural impulse.

The change in the electrical charge that provides the basis for the conduction of a neural impulse along an axon is called the _________. - synaptic cleft - action potential - resting potential - refractory period

action potential

Excess neurotransmitters are broken down or reabsorbed by axon terminal, via a process called __________. - myelin - synapse - reuptake - vesicles

reuptake
