This Plane
What is the coronal plane?
100
This artery provides the major anterior blood supply to the brain.
What is the internal carotid artery?
100
Afferent information enters a neuron via this stucture.
What is a dendrite?
100
70 mV
What is the resting membrane potential of a neuron?
100
This is almost always an excitatory neurotransmitter.
What is glutamate?
200
Includes such functions as motor and executive function.
What is the frontal lobe?
200
Provides buoyancy, protection, and waste elimination.
What is cerebral spinal fluid?
200
This neuron has it's cell body in line with dendrites at one end and an axon at the other.
What is a bipolar neuron?
200
Channels that allow a small amount of ions to flow at all times.
What are leak channels?
200
Fast neurotransmission occurs at
What are Ligand gated or voltage gated ion channels?
300
The motor division between the PNS and the CNS
What is the lower motor neuron in the spinal cord?
Can also be called the Alpha Motor Neuron or Anterior Horn cell.
300
CSF from the third ventricle reaches the fourth ventricle by traveling through this.
What is the cerebral aqueduct?
300
This cell structure integrates all information.
What is the soma or cell body?
300
The only ion whose concentration gradient goes from extracellularly to intracellular?
What is Cl-?
300
These receptors cause slower neurotransmission because they are not directly affiliated with an ion channel.
What are g-protein coupled receptors?
400
This brain structure is caudal to the cerebral cortex and dorsal to the pons.
What is the cerebellum?
400
This artery provides the major posterior blood supply.
What is the vertebral artery?
400
This structure facilitates faster action potential propagation.
What is myelin?
400
A local potential that moves the cell membrane in the positive direction.
What is an EPSP?
400
This ion, released intracellularly when an action potential reaches the axon terminal, is essential to facilitate neurotransmitter release.
What is Ca++?
500
This groove divides the frontal from the parietal cortices.
What is the central sulcus?
500
An occlusion of this cerebral artery could cause lower extremity motor deficits.
What is the Anterior Cerebral Artery?
500
This non-neuronal cell produces myelin in the CNS.
What is an oligodendrocyte?
500
This determines whether graded potentials reach an action potential threshold.
What is temporal and spacial summation?
500
Diffusion, degradation, reuptake or post synaptic receptor binding.
What happens to the neurotransmitter at the synaptic cleft?
