AP Psych Exam - Neurons

Neuron either fires completely or if does not fire at all

• All or none priciple

• efferent nuerons

• afferent neurons

• action potential

Neurons that take information from the brain to the rest of the body. They carry information that exits the brain

• afferent neurons

• efferent neurons

• action potential

• excited neurons

Neurons that take information from the senses to the brain, responsible for transmitting neural impulses from the rest of the body to the brain

• afferent neurons (sensory neurons)

• efferent neurons (motor neurons)

• neural firing

• action potential neurons

Electric charge that spreads down the length of a neuron after the threshold is achieved

• afferent neurons

• efferent neurons

• action potential

• inhibitory neurotransmitters

Chemicals released from the terminal buttons of a neuron that inhibit the next neuron from firing

• inhibitory neurotransmitters

• excitatory neurotransmitters

Chemicals released from the terminal buttons of a neuron that excite the next neuron into firing

• inhibitory neurotransmitters

• excitatory neurotransmitters

Neural cell consisting of dendrites, cell body, axon, and terminal buttons

• neuron

• spinal cord

• dendrite body

• nerve

Rootlike parts of the cell that stretch out from the cell body

• axon

• terminal buttons

• dendrite

• synapse

Contains the nucleus and other parts of the cell needed to sustain its life

• dendrite

• axon

• cell body (Soma)

• terminal buttons

Wirelike structure ending in the terminal buttons that extends from the cell body

• axon

• dendrite

• synapse

• soma
