Which structure corresponds to the Sella Turcica?

• A. Body of sphenoid
• B. Occipital bone
• C. Dorsum sellae
• D. Sella turcica

Answer: (D)

The Sella Turcica is the saddle‑shaped depression on the superior surface of the sphenoid bone. It’s the bony enclosure that houses the pituitary gland (in the hypophyseal fossa) and is formed by the tuberculum sellae in front and the dorsum sellae behind. So the structure that corresponds to the Sella Turcica is the saddle-shaped depression itself on the sphenoid bone. The occipital bone is a different part of the skull, the dorsum sellae is just the back wall of this saddle, and the body of the sphenoid contributes to the area but is not the name of the depression.
