How Do You Spell EPENDYMA LAYER?

Pronunciation: [ˈɛpəndˌɪmə lˈe͡ɪə] (IPA)

The ependyma layer is a component of the central nervous system that lines the ventricles of the brain and the central canal of the spinal cord. The word "ependyma" is spelled with the /ɛpɛn'daɪmə/ phonetic transcription, which represents the sounds of the word. The first syllable is pronounced with a short "e" followed by a long "e." The second syllable is pronounced with a short "e" followed by a stressed "aɪ" sound. The third syllable is pronounced with a short "u" sound, and the final syllable is pronounced with a short "a" sound.

EPENDYMA LAYER Meaning and Definition

1. The ependyma layer is a specific anatomical layer found in the central nervous system (CNS), comprising a specialized type of neuroglial cells called ependymal cells. This layer is typically located in close proximity to the ventricles of the brain and the central canal of the spinal cord. The ependymal cells are responsible for lining these hollow spaces, providing a protective barrier between the cerebrospinal fluid (CSF) and the surrounding neural tissue.

   The main function of the ependyma layer is to regulate the production and circulation of CSF, which is crucial for maintaining the homeostasis of the CNS. Ependymal cells possess cilia on their surfaces, which aid in the movement of CSF and contribute to its flow within the ventricular system. They also possess microvilli that absorb and secrete substances into the CSF.

   Beyond its structural role, the ependyma layer also plays a part in the production of neural stem cells, called ependymal stem cells. These cells have the potential to differentiate into various types of neuronal and glial cells, aiding in the regeneration and repair of damaged neural tissue.

   In summary, the ependyma layer consists of a specialized layer of ependymal cells that line the ventricles of the brain and the central canal of the spinal cord. It functions to regulate CSF production and circulation, as well as contribute to the creation of neural stem cells.

2. An inner layer of undifferentiated cells next to the cavity of the tube formed during the stratification of the medullary tube, and persisting throughout life.

Etymology of EPENDYMA LAYER

The word "ependyma" is derived from the Greek word "ependyma", meaning "a garment", specifically a covering layer. It comes from the Greek verb "ependymao", which means "to cover or to clothe". In the context of anatomy, the term "ependyma" refers to a thin, epithelial-like layer of cells that lines the ventricles of the brain and the central canal of the spinal cord. This layer is involved in the production and circulation of cerebrospinal fluid.
