Nerve Cell
The part of the nerve that carries a signal.
What is the axon.
What is Threshold.
Na+ and K+ are balanced during resting using this...
What is the Na+ K+ pump.
The lobe responsible for sight.
What is the Occipital Lobe.
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.
The part of a nerve that sends neurotransmitters to the dendrites of another cell.
What is the Axon Terminal.
Na+ and K+ are balanced during this stage of action potential.
What is Resting.
Even though there are positive ions inside of the nerve it is negative at resting because...
What are negative proteins.
The lobe responsible for logic and reasoning.
What is the Frontal Lobe.
The Brain Stem is an extension of what?
What is the spinal cord.
Holds the Nucleus.
What is the Soma (Cell Body).
Voltage increases making a nerve cell positive during this stage.
What is depolarization.
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.
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
Speeds up a nerve signal.
Too many K+ left the cell making it super negative during this stage of action potential.
What is Hyperpolarization.
The charge of a nerve at hyperpolarization. Include the units.
What is -75 mv
The lobe responsible for auditory sensory and speech.
What is the Temporal lobe.
Controls many vital autonomic functions such as heart rate and breathing.
What is the Medulla.
The chemical signal used by nerves.
What is a Neurotransmitter.
K+ leaves the cell changing it's charge from + to - during this stage.
What is repolarization.
What is 3 Na+ and 2K+
Part of the brain that coordinates muscle movements.
What is the Cerebellum.
Layer of the brain associated with fighting, flight, feeding and reproductive behavior.
What is the Midbrain/Limbic System.
