SUBCOMMISSURAL ORGANS Meaning and
Definition
-
Subcommissural organs are small structures found within the brain, specifically in the vertebrate brain and spinal cord. These organs are typically located near the third ventricle, a fluid-filled cavity within the brain, and are formed by a cluster of cells known as ependymal cells.
The main function of subcommissural organs is to produce and secrete a special type of glycoprotein called SCO-spondin. This glycoprotein is released into the cerebrospinal fluid and forms what is known as Reissner's fiber. Reissner's fiber is a thin, thread-like structure that extends from the subcommissural organs to the central canal of the spinal cord, helping to maintain the stability of the fluid within the ventricles.
Subcommissural organs play an important role in brain development and the regulation of cerebrospinal fluid dynamics. They have been found to be involved in the prevention of hydrocephalus, a condition characterized by an abnormal accumulation of cerebrospinal fluid within the ventricles of the brain. Dysfunction or malformation of these organs can lead to disruptions in the flow of cerebrospinal fluid and potentially result in hydrocephalus.
In summary, subcommissural organs are small structures within the brain that produce a glycoprotein known as SCO-spondin. This glycoprotein helps to maintain the stability of cerebrospinal fluid and plays a role in brain development and the prevention of hydrocephalus.

Etymology of SUBCOMMISSURAL ORGANS
The word "Subcommissural Organs" is derived from a combination of Latin and English terms.
- "Sub-" is a Latin prefix meaning "below" or "under".
- "Commissural" is derived from the Latin word "commissura", meaning "junction" or "connection".
- "Organs" is an English term referring to a part of the body that performs a specific function.
Therefore, "Subcommissural Organs" refers to the organs situated below or under a junction or connection. In anatomy, the term specifically refers to a specialized brain structure called the subcommissural organ, which is involved in the production and secretion of cerebrospinal fluid.
