Formation and development of the face and oral cavity (Orofacial Complex)

The formation and development of the face and oral cavity begins in the first branchial arch in the fourth week of intrauterine life. During this process the stomodeum is formed, which is considered the primitive mouth of the embryo.

The formation of the face starts from the five prominences (one frontonasal, two maxillary and two mandibular). The prominences develop giving rise to different regions of the face.

Muscles of Mastication in 3D - Origin, insertion and functions

The mastication is the first part of the digestive function and of great importance for stomatognathic and craniofacial development. This action is thanks to a group of muscles, known as muscles of mastication, which provide movements to the jaw.

The masticatory muscles insert into the mandible, and together with the TMJ they create opening, closing, protruding, retracting, and lateral movements. The muscles of mastication are: Temporalis, Masseter, and the pterygoid muscles (medial and lateral).
