Brain Systems
100

This brain structure regulates basic life functions like breathing and heart rate.

What is the medulla?

100

These neuron structures receive incoming signals from other neurons.

What are dendrites?

100

These specialized cells in the retina allow us to see in color and fine detail.

What are cones?

100

This neurotransmitter is heavily involved in muscle movement and memory.

What is acetylcholine?

100

This division of the nervous system controls voluntary muscle movement.

What is the somatic nervous system?

200

This structure connects the two hemispheres of the brain.

What is the corpus callosum?

200

This electrical signal travels down the axon when a neuron fires.

What is an action potential?

200

These retinal cells are most sensitive to low light conditions.

What are rods?

200

This neurotransmitter is associated with reward, motivation, and movement.

What is dopamine?

200

This division of the autonomic nervous system prepares the body for fight or flight.

What is the sympathetic nervous system?

300

This brain region is heavily involved in memory formation.

What is the hippocampus?

300

This process restores the neuron’s resting state after depolarization.

What is repolarization?

300

This depth perception cue occurs when each eye receives a slightly different image.

What is retinal disparity?

300

Low levels of this neurotransmitter are commonly linked to depression.

What is serotonin?

300

This division promotes rest, digestion, and recovery.

What is the parasympathetic nervous system?

400

This part of the brain coordinates balance and fine motor movement.

What is the cerebellum?

400

The rapid opening of sodium channels during an action potential causes this stage.

What is depolarization?

400

This monocular depth cue occurs when parallel lines appear to converge in the distance.

What is linear perspective?

400

This neurotransmitter is the primary inhibitory neurotransmitter in the brain.

What is GABA?

400

This brain system includes the amygdala, hippocampus, and hypothalamus and is involved in emotion.

What is the limbic system?

500

This structure acts as the brain’s sensory relay station for most incoming information.

What is the thalamus?

500

This insulating substance around axons speeds neural transmission.

What is myelin?

500

This binocular cue involves the inward turning of the eyes when focusing on a nearby object.

What is convergence?

500

This neurotransmitter is the main excitatory neurotransmitter in the brain.

What is glutamate?

500

This network in the brainstem regulates alertness and consciousness.

What is the reticular activating system?
