[The temporomandibular joint in different mammals. A new concept].

Abstract

The gross anatomy of the temporomandibular joints from omnivorous (pigs), carnivorous (dogs and cats), and herbivorous (cows and sheeps) animals and rodents (rabbits and mice) reveals the existence of right and left temporomandibular joint complex as has been described in humans. Each articular complex includes a temporo-meniscal joint and a mandibulomeniscal joint (in all specimens a combination between a saddle joint and condylar joint). The morphological features of these joints are discussed and the similarities and dissimilitudes between those found in animals and human beings are commented on.
