Frenulum veli

Frenulum veli is a small fold of mucous membrane that extends from the posterior border of the medulla oblongata to the cerebellum. It is located in the fourth ventricle of the brain, and is part of the ventricular system.

Etymology

The term "frenulum" is derived from the Latin word "frenum", which means "bridle". The term "veli" is derived from the Latin word "velum", which means "veil". Thus, "frenulum veli" can be translated as "bridle of the veil".

Anatomy

The frenulum veli is a small fold of mucous membrane that extends from the posterior border of the medulla oblongata to the cerebellum. It is located in the fourth ventricle of the brain, and is part of the ventricular system. The frenulum veli is attached to the taenia of the fourth ventricle, and is continuous with the inferior medullary velum.

Function

The frenulum veli, along with the rest of the ventricular system, is involved in the production and circulation of cerebrospinal fluid (CSF). The CSF is produced by the choroid plexus, and circulates through the ventricles, the subarachnoid space, and the central canal of the spinal cord. The CSF provides cushioning for the brain, removes waste products, and carries nutrients to the brain.

Clinical significance

Abnormalities or damage to the frenulum veli can lead to a variety of neurological conditions. For example, a cyst or tumor in the frenulum veli can block the flow of CSF, leading to hydrocephalus. In addition, inflammation of the frenulum veli can cause meningitis.
