Which joints are Articulatio Temporomandibularis?
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 mandible below; it is from these bones that its name is derived.
Where is the Postglenoid process?
temporal bone
The process of the temporal bone separating the mandibular fossa from the external acoustic meatus.
What is temporomandibular function?
The main function of the temporomandibular joint is to facilitate movements of the lower jaw. This joint allows a range of movements of the lower jaw, namely translational movements (protrusion/retraction and lateral deviation) and rotational movements (elevation/depression).
Where is the temporomandibular joint located?
The temporomandibular joints (TMJ) are the 2 joints that connect your lower jaw to your skull. More specifically, they are the joints that slide and rotate in front of each ear, and consist of the mandible (the lower jaw) and the temporal bone (the side and base of the skull).
What is the condyloid process?
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 a Ginglymoarthrodial joint?
The temporomandibular joint (TMJ) is a ginglymoarthrodial joint formed by the glenoid fossa of the temporal bone and the mandibular condyle. An articular disc separates the joint into two synovial cavities with distinctive movement patterns.
How is a trochoid joint formed?
trochoid joint pivot joint. temporomandibular joint (TMJ) a bicondylar joint formed by the head of the mandible and the mandibular fossa, and the articular tubercle of the temporal bone. See also temporomandibular joint disorder.
How do Trochoid joints move?
pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.
What is the ginglymus?
Definitions of ginglymus. a freely moving joint in which the bones are so articulated as to allow extensive movement in one plane. synonyms: ginglymoid joint, hinge joint.
