"Γναθού" (gnathos) is a Greek term that refers to the jaw or jawbone. It is commonly used in anatomy to describe the structure that supports the teeth and facilitates movement for chewing and speaking. The jaw is divided into two main parts: the upper jaw, known as the maxilla, and the lower jaw, called the mandible. In addition to its anatomical significance, the term "γναθού" can also be found in various fields such as dentistry and orthodontics, where understanding jaw alignment is crucial for proper dental health. Issues related to the jaw can affect overall well-being, impacting functions like eating and communication.
