“…SP-and CGRP-positive nerve fibers exist at the attachment of the lateral pterygoid muscle and the TMJ disc (Johansson, 1986;Ichikawa, 1989, Kido, 1993, Shimizu, 1996, and the distribution of these markers differ in the TMJ disc (Tahmasebi- Sarvestani, 1997Sarvestani, , 2001). Previous reports have described the vasculature and nerve structures of the side of the lateral pterygoid muscle (Griffin and Shape, 1960;Castelli, 1963;Sarnat and Engel, 1951;Parsons and Boucher, 1966). However, Anatomical study of the human discomallear ligament using cone beam computed tomography imaging and morphological observations the distribution of CGRP, PGP 9.5 and SP in the DML is yet unknown.…”
