Middle cranial fossa Skull Structure. Cavernous sinus The facial nerve and its branches pass through the parotid gland, as does the external carotid artery and retromandibular vein.The external carotid artery forms its two Skull The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. Branches of the internal carotid also supply blood to the eye, the contents of the orbit, and the forehead. It transmits the terminal branches of the inferior alveolar nerve (the mental nerve), The size varies considerably. Foramen spinosumThis small opening, located posterior-lateral to the foramen ovale, is the entry point for an important artery that supplies the covering layers surrounding the brain.

The segment of the internal carotid artery that travels above foramen lacerum is called the lacerum segment. This hole allows the internal carotid artery, one of the major blood supplies to the brain, to enter the skull. The foramen spinosum Superior orbital fissure The Skull Internal Carotid Artery and Its Aneurysms 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. It is at the end of the mandibular canal, which begins at the mandibular foramen on the posterior surface of the mandible.

The segment of the internal carotid artery that travels above foramen lacerum is called the lacerum segment. Sphenopalatine foramen 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).. This hole allows the internal carotid artery, one of the major blood supplies to the brain, to enter the skull. Within the sinus, the internal carotid artery travels anteriorly, in a horizontal manner until it reaches the anterior limit of the sinus. Behind the optic foramen the anterior clinoid process is directed backward and medialward and gives attachment to the tentorium cerebelli. Cavernous sinus In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. It is at the end of the mandibular canal, which begins at the mandibular foramen on the posterior surface of the mandible. Middle part. Jugular foramen Brain and face CT: interactive anatomy atlas - e-Anatomy - IMAIOS 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.. An alternative imaging based subclassification exists, delineated by the jugular spine which is a bony ridge partially separating the jugular foramen into two parts: Superior orbital fissure The opening to the meatus is called the porus acusticus internus or internal acoustic opening.It is located inside the posterior cranial fossa of the skull, near the center of the posterior surface of the petrous part of the temporal bone.

The Skull Foramen spinosum Foramen spinosumThis small opening, located posterior-lateral to the foramen ovale, is the entry point for an important artery that supplies the covering layers surrounding the brain. The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. It receives tributaries corresponding with the branches of the maxillary artery. Foramen magnum The posterior compartment transmits the sigmoid sinus (becoming the internal jugular vein), and some meningeal branches from the occipital artery and ascending pharyngeal artery. Pterygoid plexus The processes of the superior border of the palatine bone are separated by the sphenopalatine notch, which is converted into the sphenopalatine foramen by the under surface of the body of the sphenoid..
