What is the anatomical term for the gap between the coronoid process and the condyle process?

The anatomical term for the gap between the coronoid process and the condyle process is known as the sigmoid notch. This structure is significant in the anatomy of the mandible as it serves as a landmark for the temporomandibular joint (TMJ) and is involved in the movements of the jaw.

The sigmoid notch represents the area where the lateral pterygoid muscle attaches and plays a critical role in facilitating jaw movement. Understanding this anatomical feature is essential for dental professionals, as it can impact dental procedures and the assessment of jaw function.

In contrast, terms like alveolar notch, mandibular fossa, and maxillary arch refer to different anatomical areas or structures in the oral cavity and mandible that do not specifically indicate the gap between the coronoid and condyle processes. The alveolar notch relates to the space in the maxilla or mandible where the teeth are located. The mandibular fossa is the depression in the temporal bone where the condyle of the mandible articulates with the skull. Meanwhile, the maxillary arch refers to the upper dental arch formed by the maxilla. Each of these terms highlights other critical aspects of dental anatomy but does not describe the specific gap in question.
