Mandible

Mandible Nepean

The mandible, also known as the lower jaw or jawbone, is a remarkable bone within the human face. It stands as the largest, strongest, and lowest bone in the facial structure, serving as the foundation for the lower teeth and playing a crucial role in various functions.

Structure and Composition

The mandible is positioned beneath the maxilla, and it is unique among the bones of the skull as it is the only one capable of movement, apart from the ossicles found in the middle ear. It forms through the fusion of left and right processes during development. The meeting point of these sides, known as the mandibular symphysis, can still be faintly observed as a ridge along the midline of the jaw. This articulation, like other symphyses in the body, is characterized by the joining of bones through fibrocartilage. However, it fuses together during early childhood.

Function and Significance

The mandible plays a pivotal role in several essential functions, including:

• Supporting the lower teeth.
• Facilitating biting and chewing.
• Contributing to speech production.
• Allowing for a wide range of jaw movements, such as opening and closing.

Your jaw's health and alignment are vital for overall oral and facial well-being.
