Verified step by step guidance
1
Understand the anatomy of the sphenoid bone: The sphenoid bone is a complex bone located at the base of the skull. It has several regions, including the sella turcica, optic canal, pterygoid process, and greater wing.
Learn the function of the pituitary gland: The pituitary gland is a small endocrine gland located at the base of the brain. It sits in a protective bony structure to ensure its safety and proper positioning.
Identify the sella turcica: The sella turcica is a saddle-shaped depression in the sphenoid bone. It is specifically designed to house and protect the pituitary gland.
Compare the other regions of the sphenoid bone: The optic canal is a passage for the optic nerve, the pterygoid process is involved in muscle attachment, and the greater wing contributes to the lateral wall of the skull. None of these structures directly contact the pituitary gland.
Conclude that the sella turcica is the region of the sphenoid bone in direct contact with the pituitary gland, as it provides the anatomical space for the gland to reside.
