The temporal bones are overlaid by the sides of the head known as the temples, and house the structures of the ears.The lower seven cranial nerves and the major vessels to and from the brain traverse the temporal bone. En algunos libros de anatoma humana se afirma errneamente que la arteria cartida interna pasa a travs del foramen lacerum. In human anatomy, the pterygopalatine fossa (sphenopalatine fossa) is a fossa in the skull.A human skull contains two pterygopalatine fossaeone on the left side, and another on the right side. Base of the skull. 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 The internal carotid artery (Latin: arteria carotis interna) is an artery in the neck which supplies the anterior circulation of the brain. The incisive canals (also: "nasopalatine canals") are two bony canals of the anterior hard palate connecting the nasal cavity and the oral cavity.An incisive canal courses through each maxilla.Below, the two incisive canals typically converge medially. It is separated from the external ear by the tympanic membrane, and from the inner ear by the medial wall of the tympanic cavity. Haller cells, also known as infraorbital ethmoidal air cells, are ethmoid air cells located lateral to the maxillo-ethmoidal suture along the inferomedial orbital floor. Summary. The posterior compartment transmits the sigmoid sinus (becoming the internal jugular vein), and some meningeal branches from the occipital artery and ascending pharyngeal artery. The foramen ovale is an opening in the greater wing of the sphenoid bone. The canal is formed by a vertical groove on the posterior part of the maxillary surface Foramen spinosum, traversed by the middle meningeal vessels and usually the spinous nerve, a branch of the mandibular nerve. Thus, it is best to name lymph node groups outside of the established levels I-VI. Foramen rotundum, traversed by the maxillary nerve. Como tal, no sale del crneo a travs de dicho foramen. Foramen spinosum This 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 petrous part of the temporal bone is pyramid-shaped and is wedged in at the base of the skull between the sphenoid and occipital bones.Directed medially, forward, and a little upward, it presents a base, an apex, three surfaces, and three angles, and houses in its interior, the components of the inner ear.The petrous portion is among the most basal elements of the The supraorbital foramen is a small groove at superior and medial margin of the orbit in the frontal bone. It arches transversely below the superciliary arches and is the upper part of the brow ridge. The lymph nodes in the neck have historically been divided into at least six anatomic neck lymph node levels for the purpose of head and neck cancer staging and therapy planning.

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 Cookies allow us to analyze and store information such as the characteristics of your device as well as certain personal data (e.g., IP addresses, navigation, usage or geolocation data, unique identifiers). If the underlying artery is damaged, bleeding can cause the formation of a hematoma (collection of blood) between the brain and interior of the skull. : 771 The foramen ovale is posterolateral to the foramen rotundum and anteromedial to the foramen spinosum.Posterior and medial to the foramen is the opening for the carotid canal. 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 skull base and vault collectively form the neurocranium. The internal carotid artery (Latin: arteria carotis interna) is an artery in the neck which supplies the anterior circulation of the brain.

If "level VII" is used for superior mediastinal lymph nodes, it should refer to the extension of the paratracheal chain below the suprasternal notch but above the level of the brachiocephalic artery 4. 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. There are three foramina present in the greater wing the foramen rotundum, foramen ovale and foramen spinosum. An alternative imaging based subclassification exists, delineated by the jugular spine which is a bony ridge partially separating the jugular foramen into two parts: A jugular foramen is one of the two (left and right) large foramina (openings) in the base of the skull, located behind the carotid canal.It is formed by the temporal bone and the occipital bone.It allows many structures to pass, including the inferior petrosal sinus, three cranial nerves, the sigmoid sinus, and meningeal arteries. It is the passageway for the mandibular nerve ( a branch of the trigeminal nerve), accessory meningeal artery, lesser petrosal nerve, and emissary veins.
