postglenoid process

Posterior to the articular fossa is a sharper ridge

tempomandibular joint

The mandible is joined to the cranium by ligaments of the _____ ___ which includes the temporomandibular, stylimandibular and sphenomandibular ligaments.

Retraction

The temporomandibular joint Ligament prevents excessive _____ or moving backward of the mandible

Temporal bone

The triangle shaped temporomandibular joint Ligament has a base that is attached to the zygomatic process of the ____ _____ lateral to the articular eminence; it's apex is fixed to the lateral side of the neck of the mandible.

mandibular foramen

inferior alveolar nerve descends between the sphenomandibular Ligament and the mandibular ramus to gain access to the ____ ____ and because of its attachment to the Lingual overlaps the opening.

stylomandibular ligament

runs from the styloid process of the temporal bone to the angle of the mandible, separates the parotid and submandibular salivary glands and becomes taut when the mandible is protruded.

Temporal Bone

A cranial bone of the skull that articulates with the facial skull bones of the mandible at the TMJoint by way of the joint disc

joint capsule

A fibrous _____ _____ completely encloses the temporomandibular joint, with it superiorly wrapping around the margin of the temporal bones articular eminence and articular fossaand inferiorly wrapping around the level posteriorly and laterally at the neck, but anteriorly and medically it attaches just to the margin of the articular surface of the condyle.

stylomandibular ligament

A variable ligament formed from thickened cervical fascia in the area. Runs from the styloid process of the temporal bone to the angle of the mandible and separates the parotid and submandibular salivary glands.

Articulating fossa

Also known as the mandibular fossa or glenoid fossa is posterior to the articular eminence and consists of an oval-shaped depression on the temporal bone, which is posterior and medial to the zygomatic process of the temporal bone

TMJ

Joint on each side of the head that allows movement of the mandible for mastication, speech and respiration's.

temporomandibular Ligament

Located on the lateral side of each joint forming a reinforcement of the lateral part of the joint capsule of the TMJ

Articulating surface

Of the condyle is strongly convex in the anteroposterior direction and only slightly convex mediolaterally and is where the mandible articulates with the temporal bone.

sphenomandibular ligament

Runs from the angular spine of the sphenoid bone to the Lingual of the mandibular foramen over the mandibular foramen in the medial aspect of the mandible.

Joint Disc

The ___ ___ or meniscus is located between the temporal bone and mandiblar condyle on each side, allowing articulation between two bones at the TMJoint.

Posterior

The ____ area of attachment of the joint disc to the joint capsule is one of the locations where nerves and blood vessels enter the joint.

synovial cavities

The joint disc completely divides the TMJ into 2 compartments or ____ _____, consisting of one upper and one lower.

Lateral

The joint disc is attached to the ____ and medial pokes of the mandibular condyle.

Avascular

The joint disc is both aneaural and ____ in it's thinner middle of force bearing intermediate zone.

Thinner

With aging or trauma to the area the joint disc can become ____ or even perforated
