Cellular anatomy
Action Potential
Reflexes, sleep, and EEG, oh my!
Divisions of the Nervous System
Regions of Brain
100
What is the structure of a neuron that receives a signal
What is dendrite
100
This is the gap between two neurons
What is synaptic cleft
100
This is hydrocephalus
What is too much CSF
100
These are the two divisions of the nervous system
What is central nervous system and peripheral nervous system
100
This structure connects the two hemispheres
What is corpus callosum
200
What are the supporting cells to the neurons?
What is glial
200
When a neuron is at rest, this is its charge (do not need exact value)
What is negative
200
This is what slow-wave sleep is also known as
What is non-REM sleep
200
These are the two divisions of the peripheral nervous system
What is somatic and autonomic
200
This structure of the brain has a primary function of balance
What is cerebellum
300
This is the structure of the neuron that allows an action potential to go faster
What is myelin sheath
300
When a neuron becomes more negative this is called what
What is hyperpolarization
300
This is what an EEG measures
What is brain activity
300
These are the two divisions of the autonomic peripheral system
What is sympathetic and parasympathetic
300
These are the three meningeal layers. Where are each found?
What is pia mater, dura mater, arachnoid mater. Pia innermost, dura mater, outermost (against cranial bones), arachnoid mater is between the two.
400
This region of the neuron contains the organelles
What is cell body
400
During an action potential, there is a span of time where the sodium channels are incapable of responding to a positive charge. What is this called?
What is refractory period
400
These are the stages of a reflex arc
What is receptor, sensory neuron, interneuron, motor neuron, effector
400
This division of the autonomic system deals with "feed or breed"
What is parasympathetic
400
This region of the brain deals with integration of the senses
What is parietal lobe
500
This is an EPSP
What is causes action potential to be more likely
500
Describe in detail an action potential. Use these words: voltage-gated sodium channel, potassium, voltage-gated calcium channel, neurotransmitter, axon terminal, exocytosis, vesicles.
500
What stage is dreamless?
What is slow-wave/non-REM sleep
500
This is what ventricles do
What is store cerebrospinal fluid
500
This is the outermost area of the cerebrum. It has a lot of dark matter in comparison to the rest of the brain.
What is cerebral cortex
