Ependyma

As ependyma ( from the Greek: robe ) is a cell layer that lines the inner fluid spaces of the central nervous system, ie the ventricular system and the central channel. The ependyma separates the cerebrospinal fluid, cerebrospinal fluid, from the actual brain nerve tissue.

Histology

Ependymal cells belong to the group of the glial cells, which have a functional role for the actual neurons. Also, the epithelium of the choroid plexus is formed from specialized ependymal cells.

Histologically, there is a single layer, flat to high prismatic ( especially in the area of the third Hirnventrikels ) occupied cell line carries the cilia and microvilli. The ependymal cells are connected by zonules adhaerentes together.

Diseases

An inflammation of this layer of cells is called ependymitis. It can occur in hydrocephalus or infectious diseases such as toxoplasmosis and syphilis.

Hazards arising from the ependymal tumors are called ependymomas. From the ependymal isolated glycoproteins ( Ependymine ) to be associated with the consolidation of long term memory.
