POSTCISTERNA Meaning and
Definition
-
Postcisterna refers to a structure found within the central nervous system of certain organisms, particularly in the brains of arthropods. It is a specialized region that is positioned behind or posterior to the cisternae, which are interconnected fluid-filled spaces. These cisternae themselves are present within the insect brain, serving as crucial reservoirs for cerebrospinal fluid.
The postcisterna is responsible for performing various vital functions related to the flow and regulation of cerebrospinal fluid within the insect brain. It acts as a collecting reservoir, receiving and storing the excess fluid that is produced within the brain. This excess fluid is then pushed forward, aiding in its circulation throughout the neural tissue.
Furthermore, the postcisterna facilitates the exchange of nutrients, electrolytes, and waste products between the cerebrospinal fluid and the interconnected neural tissue. It is involved in the removal of metabolic waste and maintaining the ionic balance required for optimal neural functioning.
In addition to its essential role in fluid regulation, the postcisterna may also act as a protective cushion, helping to absorb mechanical shocks or impacts that the insect brain may experience.
Overall, the postcisterna plays a crucial role in ensuring the proper functioning of the insect central nervous system by acting as a storage and regulatory system for cerebrospinal fluid and aiding in essential exchanges between the fluid and the neural tissue.
