The Nervous System - Neuron

Front

What is the correct order of the parts of a neuron in a neural impulse?

Back

dendrite, cell body, axon, synapse

Front

What is a Schwann cell?

Back

A type of glial cell in the peripheral nervous system that forms the myelin sheath around neuronal axons.

Front

What direction does an axon conduct nerve impulses?

Back

Away from the cell body.

Front

What is the function of a dendrite?

Back

To receive signals from other neurons and transmit them to the cell body.

Front

What part of the nervous system is responsible for voluntary control of body movements?

Back

Somatic nervous system.

Front

What is the role of the cell body in a neuron?

Back

To maintain the cell and process incoming signals.

Front

What is the node of Ranvier?

Back

Gaps in the myelin sheath that facilitate rapid conduction of nerve impulses.

Front

What is the function of the axon terminal?

Back

To release neurotransmitters into the synapse.

Front

What is neuroglia?

Back

Supportive cells in the nervous system that do not conduct nerve impulses.

Front

What is the myelin sheath?

Back

A fatty layer that insulates axons and speeds up nerve impulse transmission.
