100
The mammalian nervous system is divided into these two components.
What are the peripheral nervous system and central nervous system?
100
The nervous system cells responsible for information processing and storage.
What are neurons?
100
The electrical signal that speeds down the axon from cell body to synapse.
What is the action potential (or nerve impulse)?
100
This label is used to refer to many forms of accident-induced brain damage.
What is traumatic brain injury?
100
This compact brain structure is required for good balance and fine control of movements.
What is the cerebellum?
200
The ups and downs of the cerebral surface, respectively.
What are gyruses (gyri) and sulcuses (sulci)?
200
A place where neurons meet to exchange information.
What is the synapse?
200
The speed of neural transmission depends in part on the presence of this insulative substance.
What is the myelin?
200
The severing of this structure results in the loss of bodily sensation and movement posterior to the point of damage.
What is the spinal cord?
200
Regular physical exercise is reported to reduce the symptoms of this relatively common psychiatric illness.
What is depression?
300
This subcortical region is involved in regulating controlling actions and forming 'motor memories.'
What is the basal ganglia?
300
Tree-like branches that receive incoming signals.
What are dendrites?
300
The technique that measures the electrical activity of contracting muscles.
What is electromyography?
300
Damage to this brain region can result in poor impulse control and difficulty planning complex actions.
What are the frontal lobes?
300
This condition is described as an unusually severe inability to remember past happenings.
What is amnesia?
400
Without this lobe, our perceptual experiences would be a lot less 'touching'.
What is the parietal lobe?
400
These tiny containers are filled with chemical messengers ready for release.
What are synaptic vesicles?
400
Electrical signaling in the nervous system depends on movement of these charged particles across the cell membrane.
What are ions?
400
The brain is buoyed up and buffered from shocks by this salt solution.
What is cerebral spinal fluid?
400
This neurotransmitter is released by motor neurons onto muscle fibers, causing them to contract.
What is acetylcholine?
500
Four fluid filled chambers found throughout the brain.
What are the ventricles?
500
These cells have 'stellar' abilities to support and regulate neurotransmission.
What are astrocytes?
500
The bundles of axons that travel to and from the skin and muscles.
What are peripheral nerves?
500
This is a life-threatening build-up of blood in the space beneath the thickest layer of the meninges.
What is a subdural hematoma?
500
Severe epilepsy has been treated by severing this structure, the largest communicative connection between the cerebral hemispheres.
What is the corpus callosum?
