Tuberculum sellae
Tuberculum sellae
Tuberculum sellae (pronunciation: too-ber-kyoo-lum sel-ee) is a part of the sphenoid bone in the human skull.
Etymology
The term "Tuberculum sellae" is derived from Latin, where "tuberculum" means small swelling and "sellae" refers to a saddle, indicating its saddle-like shape.
Anatomy
The Tuberculum sellae is a part of the sphenoid bone, which is one of the seven bones that make up the orbit. It is located at the front of the sella turcica, a depression in the sphenoid bone that houses the pituitary gland. The Tuberculum sellae serves as a boundary between the anterior cranial fossa and the middle cranial fossa.
Clinical Significance
The Tuberculum sellae is an important anatomical landmark in neurosurgery. It is often involved in Tuberculum sellae meningioma, a type of brain tumor that occurs in the meninges, the membranes that cover the brain and spinal cord.
