AP Psychology Unit 2.1 Nervous System & Neurons

Front

Which describes reuptake in neural communication?

Back

The absorption of neurotransmitters by a presynaptic neuron after it has sent a signal to a postsynaptic neuron.

Front

Neural firing occurs as an all-or-nothing response, which means?

Back

Neurons fire only when a certain threshold is reached.

Front

What is unique about a reflex arc?

Back

A reflex arc enables rapid responses to stimuli without brain involvement.

Front

What is the small gap between two neurons called?

Back

Synapse

Front

Which part of the neuron receives signals from other neurons?

Back

Dendrite

Front

What is a threshold in neural communication?

Back

The minimum stimulus level needed to trigger an action potential.

Front

The chemical messengers released into the spaces between neurons are called

Back

neurotransmitters

Front

What disruption to neural communication occurs in myasthenia gravis?

Back

Antibodies block acetylcholine receptors at the muscles.

Front

The depolarization of a neural membrane can create:

Back

An action potential

Front

Put the structures of a neuron in order from receiving to sending: Dendrites, Cell body, Axon, Synaptic terminals

Back

Dendrites, Cell body, Axon, Synaptic terminals
