What is the primary function of the intrinsic ligaments of the TMJ?
Show answer and explanation
Correct answer: A. Passive restriction of mandibular movement
A) Passive restriction of mandibular movement — CORRECT.
The intrinsic (true) TMJ ligaments — the lateral (temporomandibular) ligament primarily — function as passive restraints. They become taut at extremes of motion, limiting excessive movement without actively generating force.
B) Upward limitation: The ligaments do restrict certain movements but "active limitation upward" is not the standard classification. They are passive structures.
C) Proprioception is provided by muscle spindles and Golgi tendon organs — not the ligaments themselves.
D) Disc stabilization is primarily a function of the bilaminar zone and retrodiscal tissue.
