This video showcases the intricate dynamics of a healthy, dislocated, and arthritic temporomandibular joint (TMJ) articular disc. It vividly illustrates the normal structure and function of the disc, highlighting collagen and elastin composition. Transitioning to a dislocated disc, viewers witness the displacement affecting condylar bone interaction and retro-discal tissue. Finally, the video portrays the degenerative changes in an arthritic disc, emphasizing alterations in fiber orientations, collagen type I distribution, and network structures. Through light microscopy, immunofluorescence, and SEM imaging, this educational content provides a comprehensive insight into the complexities of TMJ disc health and pathology. #shorts #3danimation #tmj #health
