PERIEPENDYMAL Meaning and
Definition
-
Periependymal is an adjective used in anatomy and biology to describe structures or regions that are situated around or near the ependyma, a specialized epithelial lining that encompasses the ventricles of the brain and central canal of the spinal cord.
The ependyma is a delicate layer of cells that produces cerebrospinal fluid and acts as a barrier between the central nervous system and the cerebrospinal fluid in the ventricles or the central canal. The term periependymal is used to refer to areas or structures that immediately surround or border the ependyma.
In the context of neural tissue, periependymal regions can include neighboring cells, tissues, or structures present in close proximity to the ependyma. For example, periependymal astrocytes are a type of glial cell that are found adjacent to the ependymal lining. These astrocytes provide structural support, contribute to the blood-brain barrier, and have roles in various physiological processes.
The prefix "peri-" in periependymal conveys the meaning of "around" or "surrounding," indicating the proximity to the ependyma. The term periependymal is primarily used in scientific literature, particularly in the field of neuroanatomy and neurobiology, to describe the relationship or location of structures in relation to the ependyma.

Etymology of PERIEPENDYMAL
The word "periependymal" is derived from two parts: "peri-" and "ependymal".
1. "Peri-" is a prefix of Greek origin meaning "around" or "surrounding". It is commonly used in medical terminology to indicate something located around or near a particular structure.
2. "Ependymal" is an adjective form of the noun "ependyma", which refers to a thin membrane lining the central canal of the spinal cord and the ventricles of the brain. The term "ependymal" originates from the Greek word "ependyma", which means "garment" or "that which is put on or attached".
