The palatine bone is situated at the back part of the nasal cavity between the maxilla and the pterygoid process of the sphenoid (Fig. This bone consists of five major parts, one being the body and four being projections named processes (frontal, zygomatic, palatine, alveolar). Label the Maxilla and Palatine Bones learn by taking a quiz; Online quiz to learn Label the Maxilla and Palatine Bones; Your Skills & Rank. It is the shortest of the orbital walls (∼40 mm). The maxilla forms the upper jaw by fusing together two irregularly-shaped bones along the median palatine suture, located at the midline of the roof of the mouth. The name originates from the word palate which is a direct translation from the Latin word palatum . The palatine bones are paired L-shaped bones joined at the midline.They form the hard palate with the maxillary bones.They also form part of the floor of the nasal cavity (the hard palate separates the oral cavity from the nasal cavity).. Similar to the roof, it is triangular in shape. Advertisement. 167). Posteriorly, the floor is separated from the … The palatine bone is bordered by the maxilla anteriorly (transverse palatine suture). Every palatine bone is lodged between the pterygoid process of sphenoid bone behind and the maxilla in front. The palatine fissures, two large openings in the incisive bones, are located at the level of the canine teeth and can be palpated as soft areas in the rostral aspect of the palate bilaterally (see Fig. The palatine bones are located at the back of the nasal cavity, between the maxillae and the sphenoid. Viewed medially, the maxillary sinus is evident with its medially facing ostium. Each maxilla has four processes ( frontal, zygomatic, alveolar, and palatine) and helps form the orbit, roof of the mouth, and the lateral walls of the nasal cavity. 2 palatine bones create the posterior one-third of the hard palate that is why it is called palatine bone. Functionally, the maxillae hold the tooth roots and form most of the nasal aperture and floor, most of the hard palate, and the floors of the orbits. Total Points. 0. The maxilla (or upper jaw bone, latin: maxilla) is a paired bone that has a body and four processes: frontal process, zygomatic process, palatine process, and alveolar process.The two maxillary bones (maxillae) are fused in the midline by the intermaxillary suture to form the upper jaw.. Each maxilla has five parts, including the body of the maxilla and four processes: Maxilla Bone Anatomy The two maxilla or maxillary bones (maxillae, plural) form the upper jaw (L., mala, jaw). Posteriorly it serves as an attachment to the velum and palatine aponeurosis and the posterior border of the perpendicular plate articulates with the medial pterygoid plate of the sphenoid bone. Maxillae are a pair of bones that form the dominant portion of the face. Game Points. Palatine Bone Location. The incisive, maxillary and palatine bones form the roof of the mouth. It forms a part of the underside of the skull, and lies between the maxilla bone (the fixed, upper bone of the jaw) and the sphenoid bone (whose wings help form the base of the eye sockets and base of the skull). In the human body, this bone is located at the back of nasal cavity – between the pterygoid process of the sphenoid and the maxilla. There are two palatine bones. A palatine bone is defined as one of a pair of irregularly shaped bones located behind the maxilla which enters into the formation of the hard palate, nasal cavity and the floor of the orbit. The hard palate is the bony roof of the mouth, and is formed by the palatine processes of the maxillae and horizontal plates of the palatine bones. Gross anatomy. Today 's Points.
