What is the posterior clinoid process?
The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli. Sphenoid bone.
What is posterior Clinoid?
Description. The posterior boundary of the superior surface of sphenoid bone is formed by a square-shaped plate of bone, the dorsum sellæ; ending at its superior angles in two tubercles, the posterior clinoid processes, the size and form of which vary considerably in different individuals.
What attaches to clinoid process?
In the sphenoid bone, the posterior border, smooth and rounded, is received into the lateral fissure of the brain; the medial end of this border forms the anterior clinoid process, which gives attachment to the tentorium cerebelli; it is sometimes joined to the middle clinoid process by a spicule of bone, and when this …
Where is the posterior clinoid process found?
The anterior, middle and the posterior clinoid processes are located in the middle cranial fossa of the skull. The posterior boundary of the pituitary fossa is formed by the dorsum sellae, the supero-lateral angles of which are raised to form the posterior clinoid process.
Where is the Clinoid bone?
lesser sphenoid wing
The anterior clinoid process (ACP) is a bony projection on the medial extremity of the posterior border of the lesser sphenoid wing.
What is located in the sella turcica of sphenoid bone?
The pituitary gland is located in the sella turcica of the sphenoid bone. It is comprised primarily of an anterior and posterior part. The posterior pituitary part is connected to the hypothalamus by the median eminence via the tube-like pituitary stalk.
Where are anterior clinoid processes found?
Background: The anterior clinoid process (ACP) is located close to the optic nerve, internal carotid artery, ophthalmic artery, and can be easily injured in an ACP-related surgery. An anatomical study clearly defining the ACP is of great importance.
What passes through anterior clinoid process?
A, The carotid artery enters the cranial cavity by passing along the medial side of the anterior clinoid process and below the optic nerve.
What is anterior Clinoid process?
The anterior clinoid process (ACP) is a bony structure on the superolateral aspect of the sphenoid sinus lying between the internal carotid artery and the optic nerve.
What processes are located anterior and posterior to the sella turcica?
Anteroinferiorly, the foramen rotundum conducts V2 (maxillary division of trigeminal nerve). Posterior to the sella are the posterior clinoid processes, dorsum sellae, and interpeduncular cistern containing the basilar apex and cranial nerves III and IV.
What does the sella turcica do?
Within your skull, there’s a small, bony nook at the base of your brain that holds and protects your pituitary gland (which controls how hormones work in your body). This tiny structure is called the sella turcica.
