100

What part of the nervous system is the lizard brain a part of?  Peripheral Nervous System or Central Nervous System?

What is the Central Nervous System.

200

The part of a nerve that sends neurotransmitters to the dendrites of another cell.

What is the Axon Terminal.

200

Na+ and K+ are balanced during this stage of action potential.

What is Resting.

200

Even though there are positive ions inside of the nerve it is negative at resting because...

300

Voltage increases making a nerve cell positive during this stage.

What is depolarization.

300

During depolarization this ion enters the nerve through these two channels.  Name the ion and both channels.

What are Na+, Mechanical Channels and Voltage Gated Channels.

300

The lobe responsible for pain and touch reception.

What is the Parietal lobe.

Part of the brain stem that helps control sleep and attention.

What is the Reticular Formation

400

Speeds up a nerve signal.

What is Myelin Sheath.
400

What is the Medulla.


500

The chemical signal used by nerves.

What is a Neurotransmitter.

500

K+ leaves the cell changing it's charge from + to - during this stage.

What is repolarization.

500
During resting ___ Na+ ions move out of the cell and ___ K+ ions move into the cell.  List the numbers.

What is 3 Na+ and 2K+

500

Part of the brain that coordinates muscle movements.

What is the Cerebellum.

500

Layer of the brain associated with fighting, flight, feeding and reproductive behavior.

What is the Midbrain/Limbic System.
