Ependyma

Ependyma is a type of neuroglia that lines the ventricles of the brain and the central canal of the spinal cord. It is involved in the production and circulation of cerebrospinal fluid (CSF).

Structure

The ependyma is made up of ependymal cells, which are a type of glial cell. These cells have cilia and microvilli that aid in the circulation of CSF. The ependyma lines the ventricular system of the brain and the central canal of the spinal cord.

Function

The primary function of the ependyma is to produce and circulate CSF. The CSF serves several important functions in the central nervous system (CNS), including providing buoyancy and protection for the brain, removing waste products, and carrying nutrients to the brain.

Clinical significance

Damage or dysfunction of the ependyma can lead to a number of medical conditions. For example, hydrocephalus can occur if the flow of CSF is blocked. In addition, ependymal cells can give rise to certain types of brain tumors, such as ependymomas.
