Tempoporomandibular joint: Morphological and phisiological aspects

This is a study where 60 temporomandibular joints were analysed. Method: dissection of anatomical parts, preserving TMJ itself, pterygoid lateral muscle, and its insertions. A special study of the articular disc was performed through histological slicing, for defining its structure and insertions. Results were compared with classical descriptions of different authors. Innervation of related structures is commented, as well as clinical aspects of TMJ conditions in view of its morphological and physiological aspects. Dental occlusion guide alterations, malocclusion, interfere on the TMJ movements, leading to meniscus traumatic compres-sion with possible chronic headache syndrome.
