The condyloid process or condylar process is the process on the human and other mammalian 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.
In anatomy, the temporomandibular joints (TMJ) are the two joints connecting the jawbone to the skull. It is a bilateral synovial articulation between the temporal bone of the skull above and the condylar process of mandible below; it is from these bones that its name is derived. The joints are unique in their bilateral function, being ...
Translation Translation occurs in the upper TMJ compartment and provides most of the mandible's ability to open. Articular disc and condyle complex slide inferiorly on the articular eminences, allowing maximum depression of the mandible. [7] Maximal Mandibular Opening (T). Condylar heads are said to be at a maximum anterior-inferior position.
The condyle is the most superior part of the mandible and is part of the temporomandibular joint. [6] The mandibular notch, separating the two processes, is a deep semilunar depression and is crossed by the masseteric vessels and nerve.
Each lateral pterygoid muscle is composed of 2 heads, the upper or superior head and the lower or inferior head. The lower head originates from the lateral surface of the lateral pterygoid plate and inserts at a depression on the neck of mandibular condyle, just below the articular surface, termed the pterygoid fovea.
Posteriorly, the disc attaches superiorly to the temporal bone and inferiorly to the posterior condyle (the posterior attachments are frequently called the bilaminar zone). Laterally and medially, the disc attachments blend into the joint capsule near its attachment to the condylar head. The disc prevents the mandible from moving posteriorly. [2]
If the mandibular fossa is very shallow, this can cause problems with the strength of the temporomandibular joint. [5] This can lead to easy subluxation of the joint and trismus (lock jaw). [ 5 ] Deformation of the mandibular fossa, often part of temporomandibular dysplasia , causes similar problems in dogs .
Condyle of humerus (Condylus humeri) On the mandible, in the temporomandibular joint: Mandibular condyle; On the occipital bone, in the atlanto-occipital joint: Occipital condyles; Although not generally termed condyles, the trochlea and capitulum of the humerus act as condyles in the elbow, and the femur head acts as a condyle in the hip joint.
