From the Research
The coronoid process of the mandible lies between the masseter and lateral pterygoid muscles on a transverse head cross-section. This anatomical relationship is crucial for understanding the spatial arrangement of the muscles of mastication. The masseter muscle attaches to the lateral surface of the mandible's ramus and angle, while the lateral pterygoid muscle attaches to the pterygoid fovea on the anterior surface of the mandibular condyle. Between these two attachment points, the coronoid process serves as an important landmark and provides attachment for the temporalis muscle.
Some key points to consider include:
- The masseter and lateral pterygoid muscles play a significant role in controlling mandibular movements during chewing, speaking, and other oral functions 1.
- Understanding the spatial relationship between these muscles is essential for dental procedures, maxillofacial surgeries, and the diagnosis of temporomandibular joint disorders 2, 3.
- The coronoid process is a triangular projection of bone that extends upward and slightly forward from the anterior part of the ramus of the mandible, providing a critical attachment point for the temporalis muscle 4, 5.
- Alterations in the dimensions of the mandibular angle, such as those resulting from surgery, can affect the attachment and function of the masseter muscle, highlighting the importance of careful consideration of anatomical relationships in surgical planning 5.
