Muscles and Bones of the Head and Neck, Lateral View

Description

Seen in left lateral profile, the calvaria and facial skeleton provide the framework for the frontalis, temporalis, and the muscles of facial expression, including orbicularis oculi, zygomaticus major, and orbicularis oris as they span from the zygomatic bone and maxilla toward the modiolus. Inferiorly, the mandible is outlined along its lower border, with the ramus rising posteriorly to the temporomandibular joint where the mandibular condyle sits beneath the temporal bone at the articular eminence. Along the neck, the sternocleidomastoid runs obliquely from the mastoid process anteroinferiorly toward the manubrium and medial clavicle, while the trapezius forms a posterior-lateral sheet over the cervical region and superior thorax. Portions of the deltoid cap the lateral shoulder, and upper fibers of latissimus dorsi may be appreciated posteroinferiorly. A clear surface anatomy map. A lateral view like this earns its keep when you need to teach or plan around the TMJ and the cervical surface landmarks. The condyle, mandibular ramus, and zygomatic arch define the corridor for preauricular approaches to the joint and help explain why internal derangement or osteoarthritis of the TMJ often presents with pain just anterior to the tragus and limitation of mandibular excursion. The sternocleidomastoid and trapezius contours also anchor clinical orientation for cervical lymph node levels and for placing incisions and retractors during parotidectomy or neck dissection. Use this plate in head and neck anatomy blocks, dental and TMJ modules, and surgical training materials that pair surface form with underlying skeleton, tendon, ligament, and cartilage relationships. It also fits well in patient-facing education on jaw pain, bruxism-related myalgia, and common neck strain patterns. Anatomical accuracy verified by SciePro's Medical Advisory Board.
