The superior orbital fissure is a foramen or cleft in the skull.It lies between the lesser and greater wings of the sphenoid bone.It allows for many structures to pass, including the oculomotor nerve, the trochlear nerve, the ophthalmic nerve, the abducens nerve, the ophthalmic vein, and sympathetic fibres from the cavernous plexus IMAIOS and selected third parties, use cookies or similar technologies, in particular for audience measurement. The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. Branches of the internal carotid also supply blood to the eye, the contents of the orbit, and the forehead. The posterior compartment transmits the sigmoid sinus (becoming the internal jugular vein), and some meningeal branches from the occipital artery and ascending pharyngeal artery. In the articulated skull this foramen leads from the pterygopalatine fossa into the posterior part of the superior meatus of the nose, and transmits the Thus it receives the following veins: sphenopalatine; middle meningeal; deep temporal (anterior & posterior) it also communicates with the cavernous sinus, by branches through the foramen Vesalii, foramen ovale, and foramen lacerum. The segment of the internal carotid artery that travels above foramen lacerum is called the lacerum segment. The superior orbital fissure is a foramen or cleft in the skull.It lies between the lesser and greater wings of the sphenoid bone.It allows for many structures to pass, including the oculomotor nerve, the trochlear nerve, the ophthalmic nerve, the abducens nerve, the ophthalmic vein, and sympathetic fibres from the cavernous plexus Structure. In the adult human, the volume of the orbit is 30 millilitres (1.06 imp fl oz; 1.01 US fl oz), of which the eye occupies 6.5 ml (0.23 imp fl oz; 0.22 US fl oz). The mental foramen is located on the anterior surface of the mandible.It is directly below the commisure of the lips, and the tendon of depressor labii inferioris muscle.

The middle part of the fossa presents, in front, the chiasmatic groove and tuberculum sellae; the chiasmatic groove ends on either side at the optic foramen, which transmits the optic nerve and ophthalmic artery to the orbital cavity.. In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. The internal carotid artery does not travel through foramen lacerum. It is at the end of the mandibular canal, which begins at the mandibular foramen on the posterior surface of the mandible.

The foramen magnum (Latin: great hole) is a large, oval-shaped opening in the occipital bone of the skull.It is one of the several oval or circular openings (foramina) in the base of the skull.The spinal cord, an extension of the medulla oblongata, passes through the foramen magnum as it exits the cranial cavity.Apart from the transmission of the medulla oblongata and its It receives tributaries corresponding with the branches of the maxillary artery.

The posterior compartment transmits the sigmoid sinus (becoming the internal jugular vein), and some meningeal branches from the occipital artery and ascending pharyngeal artery. As the petrous part of the internal carotid artery leaves the carotid canal, it curves vertically and superiorly above foramen lacerum to enter the cavernous sinus.Here the artery is also referred to as the cavernous part.. Structure. The pyriform sinus (also spelled piriform sinus and also known as the pyriform recess, pyriform fossa, and smuggler's fossa) is the pear-shaped subsite of the hypopharynx located posterolaterally to either side of the laryngeal opening.

Branches of the internal carotid also supply blood to the eye, the contents of the orbit, and the forehead. This hole allows the internal carotid artery, one of the major blood supplies to the brain, to enter the skull. The foramen spinosum is a hole located in the greater wing of the sphenoid.It is located posterolateral to the foramen ovale and anterior to the sphenoidal spine.It allows the passage of the middle meningeal artery, middle meningeal vein and usually the meningeal branch of the mandibular nerve (sometimes it passes through the foramen ovale)..

Behind the optic foramen the anterior clinoid process is directed backward and medialward and gives attachment to the tentorium cerebelli.
