The sella turcica is located in the sphenoid bone behind the chiasmatic groove and the tuberculum sellae.It belongs to the middle cranial fossa. [1]The sella turcica's most inferior portion is known as the hypophyseal fossa (the "seat of the saddle"), and contains the pituitary gland (hypophysis).
The tuberculum sellae (or the tubercle of the sella turcica) is a slight [1] median elevation upon the superior aspect of the body of sphenoid bone (that forms the floor of the middle cranial fossa [2]: 508-509 ) at the anterior boundary of the sella turcica (hypophyseal (pituitary) fossa) [2]: 509 and posterior boundary of the chiasmatic groove.
On either side of the sella turcica is the carotid groove, which is broad, shallow, and curved somewhat like the italic letter f. It begins behind at the foramen lacerum , and ends on the medial side of the anterior clinoid process, where it is sometimes converted into a foramen (carotico-clinoid) by the union of the anterior with the middle ...
It sits in a protective bony enclosure called the sella turcica, covered by the dural fold diaphragma sellae. [4] The pituitary gland is composed of the anterior pituitary, the posterior pituitary, and an intermediate lobe that joins them. [5] The intermediate lobe is avascular and almost absent in humans. In many animals, these three lobes are ...
The empty sella sign is a radiological finding characterized by the partial or complete filling of the sella turcica with cerebrospinal fluid (CSF), causing the pituitary gland to appear flattened or compressed against the walls of the sella. [1] This results in the sella appearing "empty" on imaging, despite the presence of a compressed ...
The pituitary gland (or hypophysis) is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae).
Each spehoid sinus is in the body of sphenoid bone, just under the sella turcica. The sphenoid sinuses are separated from each other medially by the septum of sphenoidal sinuses, which is usually asymmetrical. [2]: 500 An opening of sphenoidal sinus forms a passage between each sphenoidal sinus [2]: 500 and the nasal cavity.
