📚 Word of the Day: Mandible /ˈmandɪbəl/
The word mandible comes from the Latin mandibula, meaning ‘jaw’ or quite literally “that which chews”, from mandere, meaning to chew. ‘Mandere’ itself traces back to an earlier Proto-Indo-European root ‘mendh’, associated with chewing and grinding.
It entered English in the early 15th century, originally used in anatomy and zoology to describe the lower jaw in humans, animals, and even insects.
In humans, the mandible is the largest and strongest bone of the face. It plays a crucial role in chewing, speaking, and facial expression, and it forms part of the temporomandibular joint (TMJ), which connects the jaw to the skull.
Because it’s so involved in everyday movement, the mandible can be affected by muscle tension, posture, and stress - making it a fascinating focus in physiotherapy and jaw-related care.
