Question

Lower Jaw is called?

Answer 1

Answer: mandible

Explanation:

The lower jaw is scientifically known as the mandible. It's one of the most important bones in your skull and plays a crucial role in eating, speaking, and facial expression. Unlike the upper jaw (maxilla), which is fixed to the skull, the mandible is the only movable bone in your skull.

The mandible is shaped like a horseshoe and forms the lower part of your face. It's the largest and strongest bone in the facial skeleton, which makes sense when you think about all the work it does every day. Every time you chew food, talk to friends, or even yawn, you're using your mandible.

The structure of the mandible includes several important parts:

• Body of the mandible - This is the horizontal, curved part that holds your lower teeth • Ramus - The vertical parts on both sides that connect to your skull • Condylar process - The rounded parts that form the jaw joint with your skull • Coronoid process - The pointed projections where jaw muscles attach • Mental foramen - Small openings that allow nerves and blood vessels to pass through

The mandible connects to your skull through the temporomandibular joint (TMJ), which allows you to open and close your mouth, move your jaw from side to side, and perform the complex movements needed for chewing. This joint is one of the most frequently used joints in your body.

Interestingly, the mandible is also important for speech production. It works together with your tongue, lips, and teeth to help you form different sounds and words clearly. Without the proper movement of your mandible, speaking would be nearly impossible.

In medical and dental studies, understanding the mandible is essential because it's commonly involved in injuries, dental procedures, and various health conditions. Dentists and doctors need to know its anatomy thoroughly to provide proper treatment and care.
