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).
Until the seventh or eighth month of fetal development, the body of the sphenoid consists of two parts: one in front of the tuberculum sellae, the presphenoid, with which the small wings are continuous; the other, consisting of the sella turcica and dorsum sellae, the postsphenoid, with which are associated the great wings, and pterygoid processes.
They vary considerably in size and form. The posterior clinoid processes deepen the sella turcica, and give attachment to (the attached border of) the tentorium cerebelli, [1]: 440, 509 and the dura forming the floor of the hypophyseal fossa (sella turcica). [1]: 441
The anterior and posterior clinoid processes surround the sella turcica like the four corners of a four poster bed. Cline is Greek for bed. –oid, as usual, indicates a similarity to. [8] The term may also come from the Greek root klinein or the Latin clinare, both meaning "sloped" as in "inclined".
The middle clinoid process is a small, bilaterally paired elevation on either side of the tuberculum sellae, at the anterior boundary of the sella turcica.A (larger) anterior clinoid process is situated lateral to each middle clinoid process.

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 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 ...
