sphenomandibulära

The term sphenomandibular refers to a anatomical relationship between the sphenoid bone and the mandible. The sphenomandibular ligament is a band of fibrous tissue that attaches the lingula of the mandible to the spine of the sphenoid bone. This ligament is a key component of the temporomandibular joint (TMJ), playing a role in its stability and movement. It originates from the petrous part of the temporal bone, specifically near the foramen spinosum, and inserts onto the medial surface of the mandible, near the mandibular foramen.

The sphenomandibular ligament assists in limiting excessive mandibular depression and protrusion. It works in conjunction with other ligaments, such as the temporomandibular ligament, to control the complex movements of the jaw. Disruptions or injuries to this ligament can potentially contribute to temporomandibular joint disorders, which can manifest as pain, clicking, or restricted movement of the jaw. Understanding the sphenomandibular ligament's anatomy and function is important in the diagnosis and treatment of various TMJ-related conditions.
