Unit 3: Nervous System Review Game

Front

What substance could leak into tissues when the spinal cord is severed and brain damage occurs?

Back

Cerebrospinal fluid

Front

How can neurons increase the strength of a nerve signal?

Back

By increasing the frequency of the action potential.

Front

Which type of neuron transmits information from the central nervous system to the rest of the body?

Back

Motor neurons

Front

What structure insulates the nerve impulse?

Back

Myelin sheath

Front

How does myelination affect the transmission of nerve impulses?

Back

It speeds up the transmission of impulses by acting as an electrical insulator.

Front

What is the role of sensory neurons?

Back

To transmit sensory information from the body to the central nervous system.

Front

What are interneurons responsible for?

Back

Connecting sensory and motor neurons within the central nervous system.

Front

What is the function of the myelin sheath?

Back

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

Front

What are nodes of Ranvier?

Back

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

Front

What is an action potential?

Back

A rapid change in electrical charge across a neuron's membrane that propagates a nerve signal.
