The articular tubercle (eminentia articularis) is a bony eminence on the temporal bone in the skull. It is a rounded eminence of the anterior root of the posterior end of the outer surface of the squama temporalis. This tubercle forms the front boundary of the mandibular fossa, and in the fresh state is covered with cartilage.
The disc is composed of dense fibrocartilagenous tissue that is positioned between the head of the mandibular condyle and the mandibular fossa of the temporal bone. The temporomandibular joints are one of the few synovial joints in the human body with an articular disc, another being the sternoclavicular joint. The disc divides each joint into ...
A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves. A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen.
In the temporal bone, the mandibular fossa is bounded anteriorly by the articular tubercle and posteriorly by the tympanic portion of the temporal bone, which separates it from the external acoustic meatus. The fossa is divided into two parts by a narrow slit, the petrotympanic fissure (Glaserian fissure).
The articular disk of the temporomandibular joint is a thin, oval plate made of non-vascular fibrous connective tissue located between the mandible's condyloid process and the cranium's mandibular fossa. Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle ...
The articular surface of the condyle is covered by fibrous tissue, and interfaces with an articular disk (or meniscus) of avascular, non-innervated fibrous tissue (collagen, fibroblasts). When the mouth is closed the meniscus is bordered medially and superiorly by the glenoid fossa of the petrous portion of the temporal bone.
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
The temporomandibular ligament originates from the lower articular tubercle of the zygomatic arch. [1] This usually has a rough surface for the ligament to attach to. [1] It attaches to the lateral and posterior border of the neck of the mandible. [1] It consists of two short, narrow fasciculi, one in front of the other. It is broader above ...
