Sella turcica
Sphenoid bone. Upper surface. (There is no label for "Sella turcica", but "Tuberculum sellae" and "Fossa hypophyseos" are visible near center.)
Medial wall of left orbit. (Sella turcica labeled in upper right.)

The Sella turcica (literally Turkish saddle) is a saddle-shaped depression in the sphenoid bone at the base of the human skull.

The seat of the saddle is known as the hypophyseal fossa which holds the pituitary gland. Located anteriorly to the hypophyseal fossa is the tuberculum sellae.

Completing the formation of the saddle posteriorly is the dorsum sellae. The dorsum sellae is terminated laterally by the posterior clinoid processes.
