What is the condyloid process of the mandible?
The condyloid process or condylar process is the process on the human mandible and some other species’ mandibles that ends in a condyle, the mandibular condyle. It is thicker than the coronoid process of the mandible and consists of two portions: the condyle and the constricted portion which supports it, the neck.
What is the coronoid process of the mandible?
In human anatomy, the mandible’s coronoid process (from Greek korone, “like a crow”) is a thin, triangular eminence, which is flattened from side to side and varies in shape and size. Its anterior border is convex and is continuous below with the anterior border of the ramus.
What is the difference between the condylar process and the coronoid process of the mandible?
The condylar process is the bony extrusion behind the coronoid process, which forms the lower bony component of the temporomandibular joint, along with the temporal bone. It is formed differently to the coronoid process, because it has a much more slender stalk with a greater protuberance to top it off.
Is the lower jaw a condyloid joint?
The mandible is the lower jaw bone that moves as we chew. When the mouth opens wide, the TMJ’s “ball,” known as the condyle, actually comes out of its socket in the skull. This socket is known as the mandibular fossa.
What is the Condyloid process?
Medical Definition of condyloid process : the rounded process by which the ramus of the mandible articulates with the temporal bone.
What part of the body is the mandible?
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear).
Which type of joint is found between the lower jaw and the skull?
fibrous joint
A gomphosis (“fastened with bolts”) is the specialized fibrous joint that anchors the root of a tooth into its bony socket within the maxillary bone (upper jaw) or mandible bone (lower jaw) of the skull. A gomphosis is also known as a peg-and-socket joint.
Where is the Condyloid process found?
The condyloid process is also located at the superior aspect of the ramus and is divided into two parts, the neck and the condyle. The neck is the thinner portion of the condyloid process that projects from the ramus.
What is the coronoid process?
The coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its medial surface, by its prominent, free margin, serves for the attachment of part of the ulnar collateral ligament.
What muscles attach to Coronoid process of mandible?
The temporalis muscle attaches to the coronoid process, and the masseter attaches to the rami. The lateral pterygoid inserts into the neck of the mandible, and the medial pterygoid inserts into the ramus near the angle of the mandible.
Where are the coronoid and condyloid processes located?
The ramus bears the coronoid process anteriorly, and the condyloid or articular process posteriorly. The angle of the mandible is at the lower posterior corner of the L shaped bone. Most of these terms are used when describing the rat mandible. The large incisor tooth extends far back into the mandible beyond the last molar tooth.
Where does the condyloid process end on the mandible?
Anatomical terms of bone. The condyloid process or condylar process is the process on the human mandible and some other species’ mandibles that ends in a condyle, the mandibular condyle.
Where is the mental foramen in the condyloid process?
On the lateral surface of the mandible, the clearly defined horizontal line of the masseteric ridge can be seen running forwards from the angle. The mental foramen is found at the anterior end of the ridge beneath the posterior end of the diastema. A notch separates the angle from the condyloid process that bears the elongated articular surface.
Is the coronoid process attached to the temporal muscle?
The coronoid process, to which is attached the temporal muscle, is much less well developed than in man, as the large masseter muscles of the rat have taken over much of the work of the temporal muscles.
