The Sphenomandibular Ligament is a thin band of connective tissue that connects the sphenoid bone of the skull to the mandible, or lower jaw. It plays a role in stabilizing the jaw during movements such as chewing and speaking. This ligament is an important part of the temporomandibular joint (TMJ) system. This ligament is often considered a remnant of the Meckel's cartilage, which is a structure present during early development. It helps support the jaw and can influence the function of the TMJ, which is crucial for proper jaw movement and overall oral health.
