Hypothalamus
Are there more glial cells or neurones in the CNS?
Glial cells
This type of cell has roles in support, maintaining blood-brain barrier, environmental homeostasis
Astrocytes
Produce myelin in the CNS
Oligodendrocytes
These cells in the CNS are similar to macrophages (i.e. hemopoietic origin). Immune monitoring and antigen presentation
Microglia
CNS cell with hemopoietic origin
Microglia
In a resting state they have an elongated nucleus and a number of short, spiny cell processes. When activated, for example by a bacterial infection, they become rounder and take on an appearance similar to a macrophage
Microglia
What are ependymal cells? (CNS)
Ciliated cuboidal/columnar epithelium that lines the ventricles
(cells generally don’t form barrier between the CSF and brain tissue)
What is a folium? (Plural folia)
Equivalent to a gyrus in the cerebellum
