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 ...
At the foramen lacerum, it unites with the (sympathetic) deep petrosal nerve, forming the nerve of the pterygoid canal (which continues anterior-ward through the pterygoid canal to reach the pterygopalatine fossa and form the pterygopalatine ganglion). [1]: 498
The nerve of the pterygoid canal (Vidian nerve) is formed by the union of the (parasympathetic) greater petrosal nerve and (sympathetic) deep petrosal nerve within the cartilaginous substance filling the foramen lacerum. From the foramen lacerum, the nerve of the pterygoid canal passes through the pterygoid canal to reach the pterygopalatine ...
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. [ 1 ]
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 ...
foramen rotundum: middle cranial fossa: pterygoid canal (Vidian) middle cranial fossa, foramen lacerum: palatovaginal canal (pharyngeal) nasal cavity/nasopharynx: Anteriorly: inferior orbital fissure: orbit: Medially: sphenopalatine foramen: nasal cavity: Laterally: pterygomaxillary fissure: infratemporal fossa: Inferiorly: greater palatine ...
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 ...
