A sensory role for the cruciate ligaments.

摘要: Morphologic, physiologic, and clinical evidence for the sensory role of cruciate ligaments is reviewed. The accommodate morphologically different nerve endings (Ruffini endings, Pacinian corpuscles, Golgi tendon organlike free endings) with capabilities providing central nervous system information not only about noxious chemical events but also characteristics movements position-related stretches these ligaments. A survey available data reveals that low threshold joint-ligament receptor (i.e., mechanoreceptor) afferents evoke weak rare effects in skeletomotor neurons (alpha-motor neurons), while they frequently powerfully influence fusimotor (gamma-motor neurons). on gamma-muscle-spindle muscles around knee are so potent even at relatively moderate loads (not noxious) may induce major changes responses muscle spindle afferents. As activity primary modifies stiffness muscles, ligament receptors, via system, participate regulation preprogramming muscular joint thereby stiffness. Thus, able to significantly contribute functional stability joint.
