Definition A muscle identified by GD Hack, a research dentist–U Maryland, Baltimore that arises in the sphenomandibular ligament and connects the sphenoid bone to the upper mandible. It stabilises the jaw during chewing rather than having a primary role in mastication. Hyperactivity of the muscle is signiﬁcantly linked to ocular-referred pain in temporomandibular syndrome.
Comment Proud colleagues ran the proposal that the muscle should be eponymically dignified as Hack’s muscle up the flagpole. Nobody saluted; musculus sphenomandibularis it is.
