Neurotransmitters
100

This system controls involuntary functions, such as: heart rate, digestion, and respiration.

What is the autonomic nervous system?

100

These cells provide structure and support neurons.

What are glial cells?

100

The membrane of the neuron is composed of this structure.

What is a lipid bilayer?

100

This process causes the neuron to become more negative than resting membrane potential.

What is hyperpolarization?

100

These molecules activate or deactivate receptors by binding to them.

What are ligands?

200

A group of cell bodies in the periphreal nervous system.

What is a ganglion?

200

This area of the neuron is responsible for signal integration.

What is the soma?

200

This protein detects chemical signals from outside the cell to trigger changes inside the cell.

What is a receptor?

200

The period in which the cell membrane cannot generate an action potential.

What is the refractory period?

200

This neurotransmitter is considered the major inhibitory neurotransmitter.

What is GABA?

300

This structure splits the cerebrum into two hemispheres.

What is the corpus callosum?

300

This structure of the neuron converts electrical signals into chemical signals.

What is the axon terminal?

300

The ratio of ions in and out of the sodium-potassium pump.

What is 3 Na+ ions out for every 2 K+ ions in?

300

The region of the neuron that generates an action potiental.

What is the axon hillock?

300

This category receptors use g proteins to cause long-lasting changes in excitability.

What are metabotropic receptors?
400

This structure of the brain is responsible for producing dopamine.

What is the midbrain?

400

These glial cells mantain the blood brain barrier.

What are astrocytes?

400

This positively charged ion has more atoms outside the cell than inside the cell.

What is potassium (K+)?

400

These proteins are activated by Ca 2+ and lead to the fusion of synaptic vesicles.

What are SNARE and SNAP proteins?

400

Dopamine and acetylcholine are examples of this category of neurotransmitter?

What is an amine?

500

The five cranial nerve pathways solely associated with motor functions.

What are oculomotor (III), trochlear (IV), abducens (VI), spinal accessory (XI), and hypoglossal (XII) cranial nerves?
500

This type of neuron is usually found in sensory pathways.

What are bipolar neurons?

500

This formula calculates the total membrane potential of the neuron.

What is the Goldman-Hodgkin-Katz equation?

500

This term describes the "jump" of potentials from node to node.

What is saltatory conduction?

500

This molecule is considered an antagonist for acetylcholine's metabotropic receptor.

What is atropine?
