Word of the Day: Jaw 🦴 /ʤɔː/
From Middle English jawe (later jowe), the word comes from Old English ceowan, meaning “to chew.” 🍽️ Scientifically known as the mandible, the jaw forms the lower part of the skull and connects to the temporal bone at the temporomandibular joint (TMJ).
This small but powerful joint is remarkably versatile - opening up to around 50 mm when you yawn 😮, gliding forward to bite 🦷, and shifting side to side as you chew or speak. It’s an extraordinary range of motion for such a compact structure - but with so much movement, things can sometimes go awry. Enter Temporomandibular joint dysfunction (TMD), which causes pain, stiffness, or clicking when the joint isn’t moving as it should.
If you’re suffering, call Patterson Allied Health on (03) 9776 1600 to learn how osteopathy may help ease jaw tension and support smoother movement. 📞
