The optic foramen is the opening to the optic canal.The canal is located in the sphenoid bone; it is bounded medially by the body of the sphenoid and laterally by the lesser wing of the sphenoid.. The superior surface of the sphenoid bone is bounded behind by a ridge, which forms the anterior border of a narrow, transverse groove, the chiasmatic groove (optic groove), above and behind which ... Optic canal contents. The optic canals are openings in the lesser wings of the sphenoid bone just medial to the anterior clinoid processes. These contain the optic nerves and their dural sheaths. Each canal also transmits an ophthalmic artery, a branch off the intradural internal carotid artery. The optic canal is a cylindrical canal running obliquely through the lesser wing of sphenoid bone near the base where it joins the body of sphenoid. It transmits the optic nerve and ophthalmic artery (and its associated sympathetic fibers). The optic canal opens into the skull base at the optic foramen.

The optic canal is the rounded gap at the tip of the pyramid shaped. It opens into the middle cranial fossa and is surrounded medially via the body of the sphenoid as well as laterally via the lesser wing of the sphenoid. The intracanalicular ophthalmic artery runs in the optic canal, inferior to the optic nerve until it emerges in the orbit. The artery gradually pierces the dura surrounding the intraorbital optic nerve to enter the subdural space. Thus, within the optic canal, the artery becomes physically separated from the optic nerve by a dural barrier.

optic canal a passage for the optic nerve and ophthalmic artery at the apex of the orbit; called also optic foramen. pulp canal root canal. root canal that part of the pulp cavity extending from the pulp chamber to the apical foramen. Called also pulp canal. Optic canal- It connects the orbit to the middle cranial fossa. It transmits the Optic nerve( surrounded by meninges) and the ophthalmic artery. Its average length is 6- 11 mm (lateral wall is shortest and medial wall is longest) 17. The contents of the optic canal and the middle portion of the superior orbital fissure course through the common tendinous ring. The superior portion transmits the lacrimal nerve (CNV1), frontal nerve (CNV1), trochlear nerve (CNIV), superior branch of the ophthalmic vein, and recurrent meningeal artery.

The optic canal permits the passage of the optic nerve (CN II) and the ophthalmic artery into the bony orbit. It is bounded medially by the body of the sphenoid, and laterally by the lesser wing of the sphenoid bone Optic Canal, Superior And Inferior Orbital Fissure We are pleased to provide you with the picture named Optic Canal, Superior And Inferior Orbital Fissure . We hope this picture Optic Canal, Superior And Inferior Orbital Fissure can help you study and research. for more anatomy content please follow us and visit our website: www.anatomynote.com. The pair of optic canals connect the middle cranial fossa with the orbits and transmit the optic nerves and ophthalmic arteries. The paired superior orbital fissure also connects this fossa with the orbit and transmits the oculomotor, trochlear, ophthalmic and abducens nerves, the ophthalmic veins, and sympathetic fibers.

The optic canal allows two very important structures to pass to and from the eye. The ophthalmic artery , which supplies blood to the retina of the eye, and the second cranial nerve (CNII), the optic nerve with its dural sheath, which sends visual information from the eye to the brain to be interpreted. The optic foramen, the opening through which the optic nerve runs back into the brain and the large ophthalmic artery enters the orbit, is at the nasal side of the apex; the superior orbital fissure is a larger hole through which pass large veins and nerves.… The margins of the opening are smooth and rounded, and the canal is short (1 cm), running laterally to the bone. The canal narrows laterally, and the lateral boundary is the fundus, where the canal splits into three distinct openings, one of which is the facial nerve canal.
