What is the horizontal plate of palatine bone?
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.
What type of bone is the palatine?
irregular facial bone
Definition. The palatine bone or os palatinum is a paired, flat, irregular facial bone. It forms part of the nasal cavity, oral cavity, and orbit of the eye. Composed of two plates, each bone sits between processes of the right or left maxilla bone and the single sphenoid bone.
Where is the 2 palatine bones located?
In anatomy, the palatine bones (/ˈpælətaɪn/) are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxillae, they comprise the hard palate. (Palate is derived from the Latin palatum.)
What does the palatine bone separate?
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).
How are palatine bones formed?
Each bone consists of a horizontal and perpendicular plate forming an L-shape. There are three processes, the pyramidal, orbital and sphenoidal. They make structural contributions to the hard palate, nasal cavity, orbital floor and pterygopalatine fossa.
Which bone contains the Palatine process?
maxilla
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest.
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.
How many palatine do we have?
two palatine bones
The two palatine bones (L., palatum “palate”) form portions of the hard palate, lateral walls of the nasal cavity, and floors of the orbits.
What is palatine in skull?
Making up a portion of the nasal cavity and palate, the palatine bone is a paired, L-shaped facial bone. 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).
What is the difference between the Palatine process and the palatine bone?
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest.
