Front

What part of the neuron houses the nucleus?

Back

Cell body.

Front

What part of the neuron can be described as a tail-like structure that carries the impulse away from the cell body?

Back

Axon.

Front

What are the two types of neuroglia in the PNS?

Back

Schwann cells and satellite cells.

Front

What is the function of Oligodendrocytes in the CNS?

Back

Wrap around axons of neurons to form myelin.

Front

What are the four types of neuroglia in the CNS?

Back

Astrocytes, Oligodendrocytes, microglia, ependymal cells.

Front

What is the role of dendrites in a neuron?

Back

Receive signals from other neurons.

Front

What is the function of the axon terminal?

Back

Transmit signals to other neurons or muscles.

Front

What is myelin and why is it important?

Back

Myelin is a fatty substance that insulates axons, speeding up signal transmission.

Front

What is the synapse?

Back

The junction between two neurons where communication occurs.

Front

What are Schwann cells?

Back

Glial cells in the PNS that form myelin around peripheral axons.
