Introduction: The sphenoid bone has a superior depression called the sella turcica, Latin for “Turkish saddle,” where the pituitary gland is found.
Where is the sella located in the brain?
The pituitary is a small gland located just underneath the brain. It is attached to the bottom of the brain by the pituitary stalk. The pituitary sits protected inside a saddle-like bony compartment in the base of the skull. This compartment is called the sella.
