The inclusion of the fascicle higher external pterygoid muscle (Lateral Pterigoid) disk articulate occurs from the middle third of the central region and contributes to the displacement of the disc and its alteration help discal displacement. On the insertion, there are differences of opinion; some consider that only a small portion of fiber is inserted into the anterior capsule and thus directly and indirectly to the disk; other researchers point out that it is directly inserted the disk and the condyle or only on the anterior edge of the capsule and the disc. The objective of the study was a histological analysis of the insertion of this muscle to differentiate the type of fibres that reach the disk articulate (proportion of collagen fibers and muscle fibers) and determine the type of union between the muscle and the disc articulate. The sample of this study of transverse and explorato...

This study aimed to determine the prevalence of posterior insertion of the superior fasciculus of the external pterygoid muscle (Lateral Pteridoideo) in anatomical preparations of adult corpses. 4 dead between 25 and 60 years was selected, was dissected up to the zygomatic fossa to expose the lateral pterygoid muscle and the components of the ATM. Subsequent insertion ratio upper lateral pterygoid muscle bundle with respect to the disc joint, joint capsule and condylar identified, being said insert was articular disk. Macroscopically, the upper bundle insertion lateral pterygoid muscle at condyle neck was observed.
