Where is the articular fossa?

The fossa is located behind the zygomatic process of the frontal bone in the anterior and lateral part of the orbital roof.

What is another term used for articular fossa?

The part of the mandible which mates to the under-surface of the disc is the condyle and the part of the temporal bone which mates to the upper surface of the disk is the articular fossa or glenoid fossa or mandibular fossa.

Is a fossa an articular surface?

It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest….

What does articular fossa and eminence of temporal bone articulate with?

articular eminence of the temporal bone that bounds the mandibular fossa anteriorly; it forms the anterior root of the zygomatic process; it is enclosed by the articular capsule of the temporomandibular joint with the articular fossa; the head of the mandible (and intervening articular disc) moves onto the articular …

What is articular capsule?

The articular capsule surrounds the joint and is continuous with the periosteum of articulating bones. It consists of two layers: Fibrous layer (outer) – consists of white fibrous tissue, known the capsular ligament. It holds together the articulating bones and supports the underlying synovium.

What is an articular eminence?

The articular eminence is a part of the temporal bone on which the condylar process slides during mandibular movements. The inclination of articular eminence varies among people and it dictates the path of condylar movement as well as the degree of rotation of the disc over the condyle.

What symptoms might a patient with a TMD have?

What are the signs and symptoms of TMD?

• Jaw discomfort or soreness (often most prevalent in the morning or late afternoon)
• Headaches.
• Pain spreading behind the eyes, in the face, shoulder, neck, and/or back.
• Earaches or ringing in the ears (not caused by an infection of the inner ear canal)
• Clicking or popping of the jaw.

What is the fossa located on the temporal bone that articulates with the mandible?

mandibular fossa
The mandibular fossa (glenoid fossa) is an oval depression behind the anterior root of the zygomatic process of temporal bone for the reception of the condyle of the mandible.

What is a articular surface?

A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement.

What is articular eminence?

What is articular disc?

The articular disk (or disc) is a thin, oval plate of fibrocartilage present in several joints which separates synovial cavities. This separation of the cavity space allows for separate movements to occur in each space.

What is the function of articular capsule in a synovial joint?

The bones of a synovial joint are surrounded by a synovial capsule, which secretes synovial fluid to lubricate and nourish the joint while acting as a shock absorber. The ends of the joint bones are covered with smooth, glass-like hyaline cartilage which reduces friction during movement.
