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. The Sella turcica (literally Turkish saddle is a saddle-shaped depression in the Sphenoid bone at the base of the Human Skull. The pituitary gland, or hypophysis, is an Endocrine gland about the size of a Pea. Located anteriorly to the hypophyseal fossa is the tuberculum sellae. In the Sphenoid bone, behind the Chiasmatic groove is an elevation the tuberculum sellæ (or the tubercle of Sella turcica)
Completing the formation of the saddle posteriorly is the dorsum sellae. In the Sphenoid bone, the anterior boundary of the Sella turcica is completed by two small eminences one on either side called the Middle clinoid processes, while The dorsum sellae is terminated laterally by the posterior clinoid processes. In the Sphenoid bone, the anterior boundary of the Sella turcica is completed by two small eminences one on either side called the Anterior clinoid processes, while
