Orbital Process Of Palatine Bone

	Orbital Process Of Palatine Bone The orbital process of the palatine bone is placed on a higher level than the sphenoidal, and is directed upward and lateralward from the front of the vertical part, to which it is connected by a constricted neck. It presents five surfaces, which enclose an air cell. Of these surfaces, three are articular and two non-articular. The articular surfaces are: # the anterior or maxillary, directed forward, lateralward, and downward, of an oblong form, and rough for articulation with the maxilla # the posterior or sphenoidal, directed backward, upward, and medialward; it presents the opening of the air cell, which usually communicates with the sphenoidal sinus; the margins of the opening are serrated for articulation with the sphenoidal concha # the medial or ethmoidal, directed forward, articulates with the labyrinth of the ethmoid. In some cases the air cell opens on this surface of the bone and then communicates with the posterior ethmoidal cells. More rarely it opens on both surface ...

	Palatine Bone In anatomy, the palatine bones (; derived from the Latin ''palatum'') are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxilla, they comprise the hard palate. Structure The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae, and the inferior orbital fissures. Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep notch, the s ...

	Inferior Orbital Fissure The inferior orbital fissure is a gap between the Greater wing of sphenoid bone, greater wing of sphenoid bone, and the maxilla. It connects the Orbit (anatomy), orbit (anteriorly) with the infratemporal fossa and pterygopalatine fossa (posteriorly). Anatomy The medial end of the inferior orbital fissure diverges laterally from the medial end of the superior orbital fissure. It is situated between the lateral wall of the orbit and the floor of the orbit. Contents The fissure gives passage to multiple structures, including: * Infraorbital nerve, Infraorbital artery, artery and Infraorbital vein, vein * Inferior ophthalmic vein * Zygomatic nerve * Orbital branches of the pharyngeal nerve * Maxillary nerve Additional images File:Gray189.png, Left infratemporal fossa.
