The temporomandibular joint (TMJ), or jaw joint, is a synovial joint that allows the complex movements necessary for life. It is the joint between condylar head of the mandible and the mandibular fossa of the temporal bone.

Oct 30, 2023 · The temporomandibular joint (TMJ) is a hinge type synovial joint that connects the mandible to the rest of the skull. More specifically, it is an articulation between the mandibular fossa and articular tubercle of the temporal bone, and the condylar process of the mandible.

Jun 14, 2021 · Renowned TMJ specialist explains muscles of TMJ disorder, why you feel muscle pain, and how to relax jaw muscles during a bout of TMJ pain

Jul 17, 2023 · TMJ derives from the first pharyngeal arch, where we can recognize a mesodermal part (muscles and vessels) and mesenchyme (from neural crests) for bones and cartilages. The development of TMJ divides into three stages: the blastemic stage; the cavitation stage and lastly, the maturation stage.

The TMJ is the only human joint that has a rigid end point (caused by the teeth coming into contact). Occlusion via the teeth maintains the vertical dimension in a sagittal plane and ensures that pressure is distributed along the whole joint.

Musculature located in the head, face, and cervical spine contributes to movement and stability of the TMJ. 29 Select musculature is represented in Figs. 1 and 2. The primary muscles are referred to as muscles of mastication because of their involvement with mechanical digestion. 15 Muscles of mastication are split into two groups: openers and ...

Dec 3, 2020 · The TMJ consist of six movements; elevation, depression, protraction, retraction, lateral excursion, and medial excursion. During chewing, the jaw is protracting (moving forward) and retracting (moving backward).

Dec 27, 2016 · Describe the anatomy of the temporomandibular joint (TMJ), including the bones, ligaments, muscles, and blood and nerve supply. Describe the biomechanics of the TMJ, including the movements, normal and abnormal joint barriers, kinesiology, and reactions to various stresses. Summarize the various causes of temporomandibular dysfunction (TMD).

May 31, 2023 · Muscles – The muscles attached to and surrounding the TMJs control their position and movement. The masseter, temporal, lateral, or external pterygoid function in coordination to close your jaw. The medial or internal pterygoid, geniohyoideus, mylohyoideus, and digastric muscles work to open your jaw.

Oct 14, 2022 · In the simplest terms, the TMJ is the articulation between the upper and lower jaws. The teeth form the contacts between the upper and lower jaws and the muscles are the motors that move the...
