AP Psych Module 9 (Neurotransmission)

What is the term for the basic building block of the nervous system (otherwise known as a nerve cell)?

• Neuron

• Gene

• Nerves

• Neurotransmitters

What is the part of a neuron that contains the nucleus?

• Cell Body

• Axon

• Myelin Sheath

• Dendrite

What part of the neuron has bushy, branching extensions that receive and integrate messages, conducting impulses toward the cell body?

• Synapse

• Axon

• Myelin Sheath

• Dendrite

What part of the neuron passes messages through its branches to other neurons or to muscles or glands?

• Synapse

• Axon

• Myelin Sheath

• Dendrite

What is a fatty tissue layer that encases axons of some neurons and enables faster transmission speed?

• Synapse

• Axon

• Myelin Sheath

• Dendrite

What supports the nervous system, nourish and protects neurons and play a role in learning, thinking and memory?

• Glial Cells

• Hormones

• Agonists

• Synapses

An action potential refers to

• a neural impulse

• a level of stimulation needed to trigger a neuron

• a period of brief resting pauce after a neuron has fired

• the junction between the axon and the dendrite

A threshold refers to

• a neural impulse

• a level of stimulation needed to trigger a neuron

• a period of brief resting pauce after a neuron has fired

• the junction between the axon and the dendrite

A refractory period refers to

• a neural impulse

• a level of stimulation needed to trigger a neuron

• a period of brief resting pauce after a neuron has fired

• the junction between the axon and the dendrite

The all or nothing response of a neuron is best compared to

• A kitchen faucet

• A shower

• A toilet

• Garden hose
