Oval Window

The oval window (Fenestra ovalis) is a window in the skull that is located between the frontal and parietal bones. It has an oval shape and serves to pass light and air into the brain.

The oval window has two membranes - external and internal. The outer membrane is made up of several layers, including the outer and inner epithelium, and a layer of cells called the endothelium. The inner membrane consists of a single layer of cells called pineocytes, which produce the fluid needed to keep the window transparent.

The oval-shaped window helps prevent brain damage from an impact or fall. In addition, the oval window is involved in metabolic processes between the blood and the brain, ensuring the supply of oxygen and nutrients, as well as the removal of carbon dioxide and metabolic products.

Malfunction of the oval window can lead to various diseases, such as aneurysm, hydrocephalus, intracranial hemorrhage and others. In some cases, the oval window may be surgically removed to treat certain conditions.

Overall, the oval window plays an important role in maintaining brain health and is an important area of ​​study for scientists and doctors.
