The superior orbital fissure is a foramen or cleft of the skull between the lesser and greater wings of the sphenoid bone. It gives passage to multiple structures, including the oculomotor nerve , trochlear nerve , ophthalmic nerve , abducens nerve , ophthalmic veins , and sympathetic fibres from the cavernous plexus .
The foramina in the base of the skull are exit and entry points for veins, arteries and cranial nerves. The cranial nerves as they exit through various foramina.
V 1 (ophthalmic nerve) is located in the superior orbital fissure V 2 (maxillary nerve) is located in the foramen rotundum. V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the ...
The inferior orbital fissure is a gap between the greater wing of sphenoid bone, and the maxilla. It connects the orbit (anteriorly) with the infratemporal fossa and pterygopalatine fossa (posteriorly).
At the front part of the cribriform plate, on either side of the crista galli, is a small fissure that is occupied by a process of dura mater. Lateral to this fissure is a notch or foramen which transmits the nasociliary nerve ; from this notch a groove extends backward to the anterior ethmoidal foramen.
In biological morphology and anatomy, a sulcus (pl.: sulci) is a furrow or fissure (Latin fissura, pl.: fissurae). It may be a groove, natural division, deep furrow, elongated cleft, or tear in the surface of a limb or an organ, most notably on the surface of the brain , but also in the lungs , certain muscles (including the heart ), as well as ...
The contents of the fissure include communications of cranial nerve VII to the infratemporal fossa. A branch of cranial nerve VII, the chorda tympani, runs through the fissure to join with the lingual nerve providing special sensory (taste) innervation to the tongue. Anterior tympanic artery and tympanic veins also pass through the structure.
