BIOL 115 Lecture Notes - Lecture 2: Fibrocartilage, Hinge Joint, Articular Disk
Document Summary
Temporal bone eminence which is sloped 70* from horizontal) Surfaces of mandibular fossa (steep posterior wall, concave fossa and articular. Non-articular surface- superior and posterior walls of fossa (thin bone does not tolerate force well) Rami- projections from posterior aspects of body. Anterior processes aka coronoid process- provides primary attachment for temporalis muscle. Posterior process aka mandibular condyle- convex articular component of. Tmj articulation surface) mandibular condyle joints (function together as part of closed chain) Temporal bone and mandible combine to create 2 separate, anatomically independent. Mandibular condyle sits in mandibular fossa of temporal bone (not suitable articular. Functional articular surface between articular eminence of temporal bone and. Convex mandibular condyle and articular eminence surfaces are convex (incongruent. Shape allows functional congruence between articular surfaces during all rom in. Superior tmj superior disc and articular eminence of temporal bone, planes of movement joint) Inferior tmj- inferior disc and mandibular head, functions as simple hinge joint.
