Neuroanatomy**** Flashcards
1
Q
what are the different kinds of glial cells and give the roles
A
astrocytes - many numerous processes. roles in support, maintaining the BBB, environmental homeostasis
oligodendrocytes - produce myelin in the CNS
microglia-cells of similar lining to macrophages - immune monitoring and antigen presentation
ependymal cells - ciliated cuboidal/columnar epithelium that lines the ventricles
2
Q
are there more glial cells or neurones
A
glial (support) cells outnumber neurones
3
Q
which cells induce endothelial cells in the capillary to maintain a tight endothelial barrier
A
astrocytes
4
Q
which cells come from the bone marrow
A
microglia
5
Q
which cells form the border and are ciliated but do not form a barrier
A
ependymal - not “true” epithelium because of this
