Morphology of the interarticular disk and its relationship with the lateral pterygoid muscle in the temporomandibular joint

Temporomandibular Joint disorder is primarily determined by the interarticular disk deformation and displacement. However, many issues connected with its histostructure, innervation, nutrition and mobility up to the present remain controversial or unsolved. Of vital importance for the joint normal performance is the relationship between the interarticular disk and the lateral pterygoid muscle, the accounts on the morphology and function of which are quite contradictory. The research goal is obtaining information on the histostructure of the interarticular disk in the temporomandibular joint and its relationship with the lateral ptervaoid muscle. The subjects of the research are temporomandibular joints dogs (n = 6).
