AP Psychology Neurotransmission

I support neurons and help produce myelin what am I?

• Axons

• Dendrites

• Glial cells

• Cell bodies

I protect the axon and help action potentials travel faster.

• Oligodendrocytes

• Glial cells

• Axon terminals

• Myelin sheath

The electrical signal that travels down an axon is called?

• Axon potential

• Action potential

• Axon terminal

• Action terminal

The receiving part of a neuron.

• Dendrite

• Axon terminal

• Axon

• Axon terminal vesicles

The inside of a neuron during its resting potential is

• +70 mv

• -70 mv

• 70 mv

• +-70 mv

A neuron can't fire for a moment after a neural impulse because it is currently in the

• Refractory period

• Threshold

• All-or-none threshold

• Action potential

After the neurotransmitter crosses he synaptic gap what process occurs?

• Reuptake

• The axon sends the message across the synaptic gap

• The resting period

• Threshold

Selective Serotonin Reuptake Inhibitors (SSRI's), such as Prozac, that block reuptake would be an example of an.

• Antagonist

• Agonist

Drugs such as Oxycodone and Heroine block production or release of neurotransmitters. These are examples of what?

• Antagonists

• Agonists

Pertaining to the charge of a neuron, which of the following is correct?

• Negatively charged sodium ions rush out of ion channels and positively charged potassium ions rush in.

• Positively charged sodium ions rush out of ion channels and negatively charged potassium ions rush in

• Positively charged sodium ions rush in to ion channels and negatively charged potassium ions rush out.
