What is the horizontal plate of palatine bone?
The horizontal plate of palatine bone is located in the transverse plane. It comprises the bony core of the posterior quarter of the hard palate and a part of the floor of the nasal cavity. The plate is quadrangular in shape, having a medial, lateral, anterior, and posterior border.
Where is the horizontal plate?
Horizontal Plate: A horizontal projection that articulates with the palatine process of the Maxilla; forms the posterior portion of the hard palate (or roof of the mouth / floor of the nasal cavity).
Which bone is horizontal in the skeleton?
palatine bone
The palatine bone has a horizontal and vertical plate as well as a pyramidal process (or pyramid-shaped portion). The horizontal plate makes up the roof of the mouth, and the rear portion of the oral cavity, just behind the nasal cavity; its front end is serrated and its back end is smoother.
What structures are included in the palatine bone?
The human palatine articulates with six bones: the sphenoid, ethmoid, maxilla, inferior nasal concha, vomer and opposite palatine. There are two important foramina in the palatine bones that transmit nerves and blood vessels to this region: the greater and lesser palatine.
What is posterior to the palatine bone?
The palatine bones contribute to the posterior part of the roof of the mouth and floor and lateral walls of the nose, the medial wall of the maxillary sinuses and the orbital floors.
Is the palatine bone part of the orbit?
The floor of the orbit consists of three bones: the maxillary bone, the palatine bone, and the orbital plate of the zygomatic bone. This part of the orbit is also the roof of the maxillary sinus.
What is palatine teeth?
Definition of Term. palatine teeth (English) Teeth present in some fishes on the palatine bones, bones that lie inside the upper jaw bones (sometimes maxillaries, sometimes premaxillaries) usually behind the vomerine tooth patch. (
Where is the orbital process of palatine bone?
Anatomical terms of 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.
Where are the palatine bones located?
nasal cavity
The small, delicate, L-shaped palatine bones form the rear of the hard palate and part of the wall and floor of the nasal cavity. Individual palatine bones are almost never found in an isolated, intact state; they generally accompany the maxillae and sphenoid, to which they are tightly bound.
Where is palatine bones?
The Adult Palatine. The palatine bones contribute to the posterior part of the roof of the mouth and floor and lateral walls of the nose, the medial wall of the maxillary sinuses and the orbital floors. Each bone (Fig. 5-66) consists of horizontal and perpendicular plates (laminae) set at right angles to each other.
What does palatine bone mean?
The palatine bone is one of the bones of the face. In humans, this bone is found between the maxilla, or upper jawbone, and the sphenoid bone, located at the base of the skull.
What is function of the palatine bone?
The Anatomy of the Palatine Bone Anatomy. The palatine bone has a horizontal and vertical plate as well as a pyramidal process (or pyramid-shaped portion). Function. Primarily, the palatine bone serves a structural function, with its shape helping carve out important structures within the head and defining the lower wall of the inside of cranium. Associated Conditions. Treatment.
Is Palatine a facial bone?
Palatine bone. The palatine bones ( /ˈpælətaɪn/) are two irregular bones of the facial skeleton in many animal species. Together with the maxillae they comprise the hard palate. ( Palate is derived from the Latin palatum, which is unrelated to palatium ‘palace’, from which other senses of palatine derive).
Is Palatine a paired bone?
The palatine bone is a paired, L-shaped bone that forms part of the nasal cavity and hard palate. It is located between the maxilla and sphenoid bone. Contents. Anatomy. Borders. Ossification . Clinical Aspects.
