No US president had a rubber jaw bone.
George Washington
US President Ulysses S. Grant was diagnosed with throat cancer, not cancer of the jaw. In 1884, he was diagnosed with squamous cell carcinoma of the throat. Grant underwent various treatments, including surgery and radiation therapy, but unfortunately, he passed away just a few days after completing his memoirs in 1885.
The jaw is a hinged joint but is special in allowing us to move it in several directions and the ability to use our top jaw as an extention of the bottom allowing us to open our mouths further.
The lower jaw enables us to chew and to speak
ears, the same as us!!! Snakes actually 'hear' though sensing vibrations in the ground. These vibrations travel along the snakes jaw-bone to the inner ear.
It is the only movable jaw in our whole body. It is also known as the lower mandible. It helps us to talk, chew food, etc.
It gives us rubber(coming from the name) and oxygen as well as many other trees
