What is anterior Clinoid?
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.
Why is it called clinoid process?
Etymology. Clinoid likely comes from the Greek root klinein or the Latin clinare, both meaning “sloped” as in “inclined.”
Where is the Clinoid located?
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 anterior Clinoid?
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 is the Clinoid bone?
clinoid process any of three processes of the sphenoid bone (anterior, medial, and posterior). coracoid process a curved process arising from the upper neck of the scapula and overhanging the shoulder joint; called also coracoid.
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 forms the anterior 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 …
What is the clinoid bone?
What is the function of clinoid process?
Their function: The anterior petroclinoid ligament acts to laterally limit the superior wall of the cavernous sinus. The posterior petroclinoid ligament limits the posterior wall of the cavernous sinus.
What is the posterior Clinoid process?
The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli.
