The structure that houses the pituitary gland is the?

• A. Optic canal
• B. Foramen magnum
• C. Sella turcica
• D. Cribriform plate

Answer: (C)

The pituitary gland sits in a saddle-shaped depression in the sphenoid bone called the sella turcica. Within this enclosure, the gland rests in the small pocket known as the hypophyseal fossa, protected by the diaphragma sellae. This location places the pituitary just below the optic chiasm and attached to the hypothalamus by the infundibulum.

The other structures have different roles: the optic canal transmits the optic nerve, the foramen magnum is the large opening at the skull base for the brainstem, and the cribriform plate is part of the ethmoid bone with openings for the olfactory nerves.
