説明

Sensory nerve endings in the monkey shoulder joint capsule were observed by light microscopy. The nerve staining technique was based upon Tago's method which was very sensitive for acetylcholinesterase (Ach E) existing in the peripheral nerve.<BR>Three distinct sensory nerve endings have b een identified: free nerve endings, Ruffini-type corpuscles, and Pacini-type corpuscles.<BR>Ruffini-typc corpuscles a n d Pacini-type corpuscles, which were thought to act as mechanoreceptors, were mainly localized in the transitional portion between the labrum and the capsule, but not within the labrum.<BR>Free ne r ve endiings, which may function as nociceptors (Pain), were distributed widely in the capsule and also in th labrum.<BR>As the results demo n strated that may mechanoreceptors exist in the capsule, it is presumed that the capsule acts not only as a static stabilizer, but also as a sensory apparatus for stress, and plays an important role in the dynamic stabilizing system. It seems that the location of the mcchanoreceptors is the optimum place for sensors to respond to the resultant force which dislocates the humeral head.<BR>Finally, we hypothesize that the dynamic stabilizing effect is performed by a series of reflex effects from the capsule to the surrounding muscle of the shoulder.
