TMJ Human Skull Model, Demonstrates Functions of Masticator Muscles, 2 partAnatomy and dental programs demonstrating temporomandibular joint mechanics and masticatory muscle function benefit from this 3B Scientific TMJ skull model, which includes represented masticatory muscles for dynamic demonstration. In this human skull model the masticatory muscles (masseter, temporal, medial and lateral pterygoid muscles) are represented as elastic bands. This skull model is suited to demonstrate the function of the masticator muscles
