Neurophysiology Flashcards
these cells support and protect neurons
neuroglia
these are nerve cells that receive stimuli and transmit APs
neurons
protuberance where axons synapse with dendrites
dendritic spines
these hold neurotransmitters at the axon terminal
synaptic vesicles
AP moving toward CNS
afferent (sensory)
AP moving away from CNS
efferent (motor)
neurons within the CNS that transmit AP from one neuron to another
interneurons
type of neuron that includes motor neurons and most neurons in CNS
multipolar
type of neuron that includes sensory neurons in the retina and in the nose
bipolar
type of neuron that has single process that divides into two branches and the part that extends to the periphery has dendrite-like sensory receptors
unipolar
this type of matter is unmyelinated axons, cell bodies, dendrites, and neuroglia
gray matter
this type of matter includes myelinated axons
white matter
organization of matter in the brain
gray on outside, white deeper
organization of matter in the spinal cord
white on outside, gray deeper
groups of cell bodies in PNS (gray matter)
ganglia
myelin in PNS
Schwann Cells
myelin in CNS
oligodendrocytes
what are 4 glial cells in the CNS
astrocytes
microglia
oligodendrocytes
ependymal cells
support cells that control extracellular environment of neurons; regulates BBB
astrocytes
“immune system” of CNS, removes cellular debris
microglia
