Neurophysiology
100
subdivision of PNS that controls contraction of skeletal muscles
What is somatic nervous system?
100
cytoplasm surrounding the nucleus
What is perikaryon?
100
neuron with 2 or more dendrites and single axon
What is multipolar?
100
myelinate PNS neurons
What are Schwann cells?
100
RMP
What is -70mV?
200
Division of PNS that brings sensory information to the CNS
What is afferent?
200
Cell structure that meets high energy demands of an active neuron
What is the mitochondria?
200
most sensory neurons of PNS are these types
What is unipolar?
200
surround neuron cell bodies of ganglia while regulating gas, nutrient, and neurotransmitter levels
What are satellite cells?
200
In the process of restoring RMP, these ions move out of neuron
What are K+?
300
Subdivision of PNS that automatically controls smooth muscle, cardiac muscle, and glands on subconscious level
What is autonomic or visceral motor system?
300
Areas of perikaryon dense with RER and free ribosomes
What are Nissl bodies?
300
dendrites and axons continuous or fused with cell body to the side
What is unipolar?
300
remove cell debris and waste in CNS
What are microglia?
300
Threshold
What is -60 to -55 mV?
400
Subdivisions of ANS that have antagonistic effects
What is sympathetic and parasympathetic?
400
Spiny processes extending out from cell body
What are dendrites?
400
outnumber all other types of neurons combined
What are interneurons?
400
line ventricles of brain and spinal cord
What are ependymal cells?
400
time when neuron cannot respond to additional depolarizing stimuli
What is refractory period?
500
Sensory structures that detect changes in environment
What are receptors?
500
Finest extensions of an axon
What are telodendria?
500
monitor outside world and our position within it
What are somatic sensory neurons?
500
maintain blood-brain-barrier
What are astrocytes?
500
over time, returns intracellular and extracellular ion concentrations to prestimulation levels
What is sodium-potassium pump?
