cells in neuro Flashcards
macroglia
astrocytes, oligodendrocytes, schwann, glioblasts
microglia
macrophage cells that are primary immune cells
ependymal
thin neuroepithelium lines ventricles and central canal
astrocytes
fibrous, short dendrites, create and maintain brain environment. Store and distribute substrates and control development. produce synapses.
Cover the basal lamina to neuromuscular bridge to manage blood flow
fibrous astrocytes
white matter, many fibrils, relatively few organelles, and exhibit long unbranched cellular processes.
protoplasmic astrocytes
occur in the gray matter of the central nervous system. They have fewer fibrils within their cytoplasm, and cytoplasmic organelles are sparse. make contact with capillaries
how do astrocytes manage blood flow
bridge neurone to BV
if neurone firing, increase Ca2+ release in astrocyte, release vocative substance that changes diameter of vessel to manage blood flow
ependyma?
ciliated cuboidal and form the choroid plexus. allow signals to pass from CSF to CNS
