It is situated anteromedially to the carotid canal. [1]: 776 The internal carotid artery passes from the carotid canal in the base of the skull, emerging and coursing superior to foramen lacerum as it exits the carotid canal; the internal carotid artery does not travel through foramen lacerum (the segment of the internal carotid artery that travels superior to the foramen lacerum is called the ...
Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening between the venous and arterial sides of the fetal heart; Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels; Greater sciatic foramen, a major foramen of the pelvis
The external opening of carotid canal (Latin: "apertura externa canalis carotici") is located upon the inferior aspect of the petrous part of the temporal bone.It is situated anterior to the jugular fossa (the two being separated by a ridge upon which the tympanic canaliculus opens inferiorly), [3] and posterolateral to the foramen lacerum.
The foramen magnum is a very important feature in bipedal mammals. One of the attributes of a biped's foramen magnum is a forward shift of the anterior border of the cerebellar tentorium; this is caused by the shortening of the cranial base. Studies on the foramen magnum position have shown a connection to the functional influences of both ...
The lacerum segment, or C3, is a short segment that begins above the foramen lacerum and ends at the petrolingual ligament, a reflection of periosteum between the lingula and petrous apex (or petrosal process) of the sphenoid bone. The lacerum portion is still considered "extradural" since it is surrounded by periosteum and fibrocartilage along ...

The pterygoid canal (also vidian canal) is a passage in the sphenoid bone of the skull leading from just anterior to the foramen lacerum in the middle cranial fossa to the pterygopalatine fossa.
Lateral to the foramen ovale is the foramen spinosum, for the passage of the middle meningeal vessels, and a recurrent branch from the mandibular nerve. Medial to the foramen ovale is the foramen lacerum ; in the fresh state the lower part of this aperture is filled up by a layer of fibrocartilage , while its upper and inner parts transmit the ...
