Definition of ependyma in English: ependymanoun ɛˈpɛndɪməəˈpendəmə mass nounAnatomy The thin membrane of glial cells lining the ventricles of the brain and the central canal of the spinal cord. Example sentencesExamples - The adjacent cerebral parenchyma and overlying ependyma revealed no discrete inflammation or vasculitis.
- These include the respiratory epithelium of the airways (respiratory cilia), the embryonic node (primary cilia), and the ependyma of the brain ventricles (ependymal cilia).
- After the ependyma covering its ventricular surface is stripped away, the elongated caudate nucleus is exposed.
- Supporting cells of the nervous system include the capsule or satellite cells of peripheral ganglia, ependyma, neuroglia, and Schwann cells.
- The most cogent theory that supports the occasional finding of subcutaneous islands of ependyma in the postcoccygeal region in infants is that these lesions originate from extramedullary ependymal rests.
Derivatives adjective Anatomy Both spindle cells and ependymal cells were positive for vimentin. Example sentencesExamples - Characteristically, meningitis, through retrograde spread, often leads to ependymitis (inflammation of the ependymal lining of the ventricular system).
- Dural, leptomeningeal, or ependymal enhancement are typical findings, none of which were present in this patient.
- Thus, an ependymal rest trapped in the developing mesonephros could potentially migrate with the tissues of the incipient broad ligament and fuse with the anterior bladder wall.
- Choroid plexus and ependymal cells are quite similar, with the latter showing more ‘degenerative’ cytologic features and fewer cellular clusters.
Origin Late 19th century: from Greek ependuma, from ependuein 'put on over'.
