  2. Sella turcica - Wikipedia

    en.wikipedia.org/wiki/Sella_turcica

    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).

  3. Tuberculum sellae - Wikipedia

    en.wikipedia.org/wiki/Tuberculum_sellae

    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.

  4. Middle cranial fossa - Wikipedia

    en.wikipedia.org/wiki/Middle_cranial_fossa

    The middle cranial fossa is formed by the sphenoid bones, and the temporal bones. It lodges the temporal lobes, and the pituitary gland. [1] [2] It is deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior cranial fossa by the clivus and the petrous crest.

  5. Pituitary gland - Wikipedia

    en.wikipedia.org/wiki/Pituitary_gland

    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 ...

  6. Empty sella syndrome - Wikipedia

    en.wikipedia.org/wiki/Empty_sella_syndrome

    Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.

  7. Sphenoid bone - Wikipedia

    en.wikipedia.org/wiki/Sphenoid_bone

    The orbital plate and that part of the sphenoid, which is found in the temporal fossa, as well as the lateral pterygoid plate, are ossified in membrane (Fawcett). Soon after, the centers for the postsphenoid part of the body appear, one on either side of the sella turcica, and become blended together about the middle of fetal life.

  8. Body of sphenoid bone - Wikipedia

    en.wikipedia.org/wiki/Body_of_sphenoid_bone

    The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli. On either side of the dorsum sellae is a notch for the passage of the abducent nerve , and below the notch a sharp process, the petrosal process, which articulates with the apex of the petrous portion of the temporal bone , and forms the ...
