sella turcica
The sella turcica (''Turkish Chair'') is a saddle-shaped depression in the body of the sphenoid bone of the human skull and of the skulls of other Hominidae including chimpanzees, orangutans, and gorillas. It serves as a cephalometric landmark.
==Structure==
The seat of the saddle is known as the hypophyseal fossa, which holds the pituitary gland. The hypophyseal fossa is located in a depression in the body of the sphenoid bone. Located anteriorly to the hypophyseal fossa is the tuberculum sellae.
Completing the formation of the saddle posteriorly is the dorsum sellae, which is continuous with the clivus, inferoposteriorly. The dorsum sellae is terminated laterally by the posterior clinoid processes.
