Neuron Structure

Front

What is the long, fiber-like part of a neuron that sends information to receiving neurons?

Back

Axon

Front

What part of the neuron releases neurotransmitters into the synaptic cleft?

Back

Axon terminal

Front

What is the function of axon terminals in a neuron?

Back

They transmit signals to other neurons by releasing neurotransmitters.

Front

Where is myelin, an insulating material, found in the neuron?

Back

Schwann cells

Front

What part of the neuron receives messages from adjacent neurons?

Back

Dendrite

Front

What is the role of dendrites in a neuron?

Back

They receive signals from other neurons.

Front

What is the function of Schwann cells in the nervous system?

Back

They produce myelin, which insulates axons.

Front

What is the synaptic cleft?

Back

The gap between the axon terminal of one neuron and the dendrite of another.

Front

What are neurotransmitters?

Back

Chemical messengers that transmit signals across the synaptic cleft.

Front

What is the significance of the Node of Ranvier?

Back

It allows for the rapid conduction of nerve impulses along myelinated axons.
