Supportive Cells Flashcards
neuroglia are cells that perform various
supportive and protective roles for the neurons
oligodendrocytes are found where?
CNS
oligodendrocytes resemble
an octopus because it has 15 arms
oligodendrocyte arms reach out and wrap around a nerve fiber
like electrical tape on a wire
oligodendrocytes wrapping around a fiber creates
a myelin sheath
myelin sheath
insulates the nerve fiber from the ECF and speeds up signals conduction in the nerve fiber
ependymal is found where?
CNS
ependymal resemble
cuboidal epithelium
ependymal lines the
internal cavities of the CNS
does ependymal have a basement membrane?
no
ependymal exhibits what kind of process that penetrate the underlying tissue
rootlike
ependymal produces what?
cerebral spinal fluid(CSF)
microglia are found where?
CNS
microglia has what kind of process?
long thorny
what do microglia processes touch?
nearby neurons
