Abstract

Among the animal species used as an experimental model is the guinea pig (Cavia porcellus [Linnaeus, 1758]). Rodents in general are widely used in pharmacological and physiological experiments, since they have many similarities with humans. A region often studied in laboratory animals is the temporomandibular joint (TMJ). It is an element of the stomatognathic system composed of several internal and external structures, capable of performing complex movements. The region is well studied because it has frequent problems in humans and animals, such as temporomandibular disorders (TMD), among others. Thus, this work was developed in order to describe the morphology of the TMJ of mice by dissection mesoscopic and microscopic analysis by scanning electron microscopy. (AU)
