Action Potential, Synapses, & Neurons Test

Front

What are neurotransmitters?

Back

Chemical messengers released from the presynaptic neuron that transmit signals across the synapse to the post-synaptic neuron.

Front

Where are neurotransmitters released from?

Back

Presynaptic neuron.

Front

What is the synaptic cleft?

Back

The gap between the presynaptic cell and the post-synaptic cell where neurotransmitters are released.

Front

In what form are nerve impulses sent within a neuron?

Back

Electrical.

Front

What does the letter 'A' represent in a labeled neuron diagram?

Back

Dendrite.

Front

What is the function of the axon terminal button?

Back

To release neurotransmitters into the synaptic cleft.

Front

What is the role of dendrites in a neuron?

Back

To receive signals from other neurons.

Front

What is the primary function of the axon?

Back

To transmit electrical impulses away from the cell body.

Front

What is the difference between electrical and chemical signaling in neurons?

Back

Electrical signaling occurs within the neuron, while chemical signaling occurs between neurons at synapses.

Front

What happens during the process of synaptic transmission?

Back

Neurotransmitters are released from the presynaptic neuron, cross the synaptic cleft, and bind to receptors on the post-synaptic neuron.
