Cell Block
The blood-brain barrier is made by this type of glial cell
Astrocytes
These types of potentials are "all or nothing"
Action potentials
Personality, time management, and planning are all functions carried out by this lobe
Frontal lobe
The term "nerve fiber" refers to this specific part of a neuron
Axon
There are this many cranial nerves
12
These glial cells are affected by multiple sclerosis
Oligodendrocytes
The resting membrane potential of neurons is ____________.
-70 mV
This structure is the sensory relay station of the brain. It sends sensory info to exactly where it needs to go.
Thalamus
Gray matter consists of a large concentration of this specific cell part
Cell bodies
This nerve innervates most of the eye muscles, including the one that constricts the pupil.
Occulomotor
Action potentials are generated at this specific part of the neuron
Axon hillock
These types of potentials are graded, can summate, and are not large enough to reach the membrane threshold.
Local potentials
The _________ is responsible for all of your big emotions.
Limbic system
The __________ system carries involuntary motor commands to the muscles of your digestive tract, respiratory tract, and blood vessels
Autonomic (sympathetic & parasympathetic)
This nerve carries sensory information from the face
Trigeminal
A group of cell bodies in the PNS are called ____________
Ganglion
When the membrane potential reaches +30 mV, these types of channels open.
Voltage-gated potassium channels
The primary motor cortex will be found in this specific location.
Pre-central gyrus
Afferent information is carried ____________ the CNS (toward/away from)
Toward
The glossopharyngeal nerve carries this type of information (sensory, motor, both)
Both
Ependymal cells make _____________
Cerebrospinal fluid (CSF)
This specific type of local potential will make it LESS likely for an action potential to occur.
IPSP
This area is responsible for understanding spoken language.
Wernicke's area
The cranial nerves are part of this division of the nervous system
Peripheral nervous system
To test the function of the accessory nerve, what movements would you ask your patient to do?
Shrug shoulders, turn head
