How many jaws do dogs have? - in detail
Dogs, like most mammals, possess a single jaw, which is known as the mandible or lower jaw. This jawbone is crucial for several functions, including eating, barking, and even expressing emotions through facial expressions. The mandible is connected to the skull by the temporomandibular joint (TMJ), allowing it to move up and down, side to side, and in a circular motion.
The upper jaw of dogs is actually part of the skull and is called the maxilla. It houses the teeth and works together with the mandible to facilitate chewing and other oral activities. The powerful muscles attached to the mandible enable dogs to exert significant force when biting or chewing, making their jaws highly efficient for various tasks.
In summary, while dogs have a single lower jaw (mandible), their upper jaw is integrated into the skull as the maxilla. This structure allows for effective and versatile use of their mouths in daily life.
