Torus tubarius

Torus Tubarius

The Torus Tubarius, also known as the tubal tonsil, is a part of the human body located in the nasopharynx. It is a part of the lymphatic system and plays a crucial role in the body's immune response.

Etymology

The term "Torus Tubarius" is derived from Latin, where "torus" means a bulging or protruding part, and "tubarius" refers to a tube. This is in reference to the structure's location near the Eustachian tube.

Anatomy

The Torus Tubarius is a mucosal elevation in the lateral wall of the nasopharynx, caused by the cartilaginous part of the Eustachian tube opening into the nasopharynx. It is located posterior to the nasal cavity and above the soft palate. The Torus Tubarius is surrounded by the pharyngeal tonsil and the salpingopharyngeal fold.

Function

The Torus Tubarius, as part of the lymphatic system, plays a crucial role in the body's immune response. It helps to filter out bacteria and other foreign particles that enter the body through the nose or mouth, preventing them from reaching the lungs and other parts of the body.
