This specimen provides a detailed view of the infratemporal fossa and surrounding neck structures. Mandible and Infratemporal Fossa The ramus, coronoid process, and mandibular head have been removed to expose the deep infratemporal fossa. The pterygoid muscles are removed to show the lateral pterygoid plate and posterior surface of the maxilla. The buccinator remains visible, originating from the maxilla, pterygomandibular raphe, and mandible. The superior constrictor muscle arises from the posterior pterygomandibular raphe, and the internal laryngeal nerve is preserved. Neck Muscles and Styloid Region Identifiable neck muscles include the mylohyoid, strap muscles, and inferior constrictor. The styloid muscles descend from the styloid process to their insertions, and the internal carotid artery is visible deep to the styloid, near the origins of stylohyoid, styloglossus, and stylopharyngeus. Medial Sagittal View The medial sagittal surface reveals the lateral wall of the nasal cavity (superior, middle, and inferior conchae; sphenoethmoidal recess; superior, middle, and inferior meatuses), nasopharynx, auditory tube opening, hard and soft palate, oropharynx, laryngopharynx, hyoid bone, and laryngeal cartilages. Tongue muscles, laryngeal, and pharyngeal structures are clearly visible. Cervical Spine The mid-sagittal cut displays the vertebral bodies of C2–C5, the atlas (C1) arch, and the dens of the axis (C2).
