Neuron Structure and function

Front

What is the tiny gap between neurons where nerve impulses are sent from one neuron to another?

Back

Synapse

Front

What is the chemical produced by neurons that carries messages to other neurons?

Back

Neurotransmitter

Front

What insulating material forms a layer around the axon of a neuron?

Back

Myelin sheath

Front

What is the part of the neuron that contains the nucleus?

Back

Cell body

Front

What structure is responsible for all the instructions of the neuron cell?

Back

Nucleus

Front

What are the branching extensions of a neuron that receive signals from other neurons?

Back

Dendrites

Front

What is the long, slender projection of a neuron that conducts electrical impulses away from the cell body?

Back

Axon

Front

What is the function of the myelin sheath?

Back

To insulate the axon and increase the speed of nerve impulse transmission.

Front

What are vesicles in the context of neuron function?

Back

Small membrane-bound sacs that store neurotransmitters and release them into the synapse.

Front

What is the role of neurotransmitters in synaptic transmission?

Back

They transmit signals across the synapse from one neuron to another.
