MANDIBULAR ARCH Meaning and
Definition
-
The mandibular arch is a term commonly used in the field of dentistry and anatomy to refer to the lower jaw or mandible. It is an essential component of the oral cavity and consists of the lower teeth, supporting structures, and the surrounding tissues.
Anatomically, the mandibular arch can be described as a U-shaped structure that articulates with the temporomandibular joint. It plays a crucial role in various functions, such as chewing, speaking, and maintaining proper occlusion. The arch is primarily comprised of the alveolar process, which contains the sockets for the lower teeth. These teeth are positioned within the arch proportional to their respective dental formula.
Additionally, the mandibular arch is supported by various muscles, including the masseter, temporalis, and medial and lateral pterygoids. These muscles aid in the movement of the mandible, allowing for functions like opening and closing the mouth and mastication.
Furthermore, the mandibular arch is encompassed by the oral mucosa, the soft tissues that cover the inner surfaces of the mouth. It provides protection and lubrication to the underlying structures, aiding in various oral functions.
Overall, the mandibular arch is a vital component of the oral cavity, playing a crucial role in dental health, speech, and overall well-being.

Etymology of MANDIBULAR ARCH
The word "mandibular" originates from the Latin term "mandibula", which means "jawbone". It is derived from the Latin verb "mandere", meaning "to chew".
The word "arch" comes from the Old English word "arce", which refers to a structure that forms a curved shape or a vault. It can also be traced back to the Latin word "arca", which means "strongbox" or "chest".
Therefore, "mandibular arch" refers to the curved structure or framework formed by the jawbones or jawbone-related structures.
