Posterior limit of mandibular movements is best described by which statement?

• A. Condyles Undergo a Twisting Around the Insertion of the Temporo-Mandibular Ligaments
• B. Condyles Are Located in the Highest and Posterior Portion of the Glenoid Cavity
• C. Condyles Are Located Below and Anteriorly to the Glenoid Cavity
• D. The Mandible Is in Centric Relation

Answer: (B)

The posterior limit of mandibular movements is the retrusive position where the condyles slide up toward the back and top of the glenoid fossa, seating against the posterior wall near the articular eminence. This is the furthest back the mandible can move while the condyles remain in the fossa, so describing them as located in the highest and posterior portion of the glenoid cavity accurately captures that terminal position. Other ideas don’t fit this limit: twisting around ligament insertions describes rotation rather than the end position of retrusion; condyles below and anterior to the glenoid cavity would be an inferior-anterior position, not the posterior limit; centric relation is a defined reproducible position often associated with the condyles being more superior-anterior against the eminence, not the posterior-most point.
