The term "γνάθος" (gnathos) refers to the jaw, a crucial part of the human anatomy. It plays a vital role in functions such as chewing, speaking, and breathing. The jaw consists of two main parts: the upper jaw, known as the maxilla, and the lower jaw, called the mandible. In addition to its anatomical significance, the jaw is also important in various fields, including dentistry and orthodontics. Proper alignment and function of the jaw can affect overall health, influencing issues like TMJ disorders and dental problems. Understanding the jaw's structure helps in diagnosing and treating these conditions effectively.
