Taenia of fourth ventricle

Taenia of Fourth Ventricle

The Taenia of Fourth Ventricle is a term used in neuroanatomy to describe certain structures associated with the fourth ventricle of the brain. The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. These ventricles together form part of the ventricular system and are responsible for the production, transport, and removal of cerebrospinal fluid.

Anatomy

The taeniae of the fourth ventricle are two thin, white, and somewhat flattened bands, each about 2 cm in length, which extend from the inferior cerebellar peduncle to the superior medullary velum. They are situated one on either side of the fourth ventricle, and serve to mark its lateral boundaries.

Function

The taeniae of the fourth ventricle are not directly involved in the production or circulation of cerebrospinal fluid. Instead, they serve a structural role, helping to maintain the shape and position of the fourth ventricle within the brain.

Clinical Significance

While the taeniae of the fourth ventricle are not typically involved in disease processes, their location and relationship to other structures in the brain can make them important in the diagnosis and treatment of certain neurological conditions. For example, they may be involved in the surgical approach to tumors of the fourth ventricle.
