The infratemporal fossa is an irregularly shaped cavity that is a part of the skull.It is situated below and medial to the zygomatic arch.It is not fully enclosed by bone in all directions. A. vomer. From this canal, accessory canals branch off; these are known as the lesser palatine canals.. The meningeal branch, also known as the nervus spinosus, is the earliest branch of the mandibular nerve.Even though it originates outside the skull, the nerve re-enters the neurocranium by going back through the foramen spinosum. foramen ovale, foramen spinosum, and the foramen rotundum. The external opening of the carotid canal is located posterolaterally to the foramen lacerum. The optic canal that opens posteriorly into the cranial cavity and transmits the optic nerve and ophthalmic artery. The arachnoid mater is a loose layer, named after its spider like appearance. : . 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.. : 4 The Locomotor System (Musculoskeletal System). It transmits the terminal branches of the inferior alveolar nerve (the mental nerve), Pronounced brow ridges were a common feature among paleolithic humans. Its outer surface is rough and gives attachment to the occipitalis and posterior auricular muscles.It is perforated by numerous foramina (holes); for example, the mastoid foramen is situated near the posterior border and transmits a vein to the transverse sinus and a small branch of the occipital artery to the dura mater.The position and size of this foramen are : 776 the basilar part of occipital bone, forming the posteromedial border. Jugular foramen It transmits the facial (VII) and vestibulocochlear (VIII) cranial nerves into a canal in the petrous temporal bone. B. ethmoid bone.
