The Synapse

What is a synapse?

• A structure that permits a neuron to pass an electrical or chemical signal to another neuron.

• A structure that permits a neuron to pass an electrical signal to another neuron.

• A structure that permits a neuron to pass a chemical signal to another neuron.

• A structure that permits a neuron to pass a mechanical signal to another neuron.

What triggers the release of neurotransmitters in a synapse?

• An electrical impulse traveling along an axon of a neuron.

• A chemical impulse traveling along an axon of a neuron.

• A mechanical impulse traveling along an axon of a neuron.

• A thermal impulse traveling along an axon of a neuron.

What happens when neurotransmitters bind with receptor molecules on the membrane of the next neuron?

• It stimulates the second neuron to transmit an electrical impulse.

• It stimulates the second neuron to transmit a chemical impulse.

• It stimulates the second neuron to transmit a mechanical impulse.

• It stimulates the second neuron to transmit a thermal impulse.

What is the direction of the nerve impulse in a synapse?

• From the first neuron to the second neuron.

• From the second neuron to the first neuron.

• Both from the first neuron to the second neuron and from the second neuron to the first neuron.

• There is no specific direction.
