The kidneys are vital organs responsible for filtering waste, balancing electrolytes, and regulating blood pressure. They are classified as retroperitoneal organs, meaning they are located behind the peritoneum, the membrane lining the abdominal cavity. Unlike intraperitoneal organs, which are fully enclosed by the peritoneum, the kidneys are only partially covered by peritoneum on their anterior … Read more
The innermost layer of the eye is called the retina. This delicate and highly specialized layer plays a critical role in vision by converting light into electrical signals that the brain interprets as images. Without the retina, the eye would be unable to process visual information. Understanding the structure, function, and importance of the retina … Read more
The inner ear is a complex structure responsible for both hearing and balance. Two of its most essential components are the vestibule and the cochlea. The vestibule plays a crucial role in maintaining equilibrium, while the cochlea is responsible for converting sound waves into nerve impulses that the brain can interpret as hearing. In this … Read more
The incisive fossa is a small but important depression located in the maxilla, the upper jawbone. This anatomical feature plays a crucial role in the structure of the face and oral cavity, serving as a passage for nerves and blood vessels.
