Final answer:
The human mouth has two sections known as the maxillary and mandibular arches, with the maxillary arch forming part of the upper jaw and the mandibular arch forming part of the lower jaw.
Step-by-step explanation:
The human mouth is divided into two sections, or arches. These are known as the maxillary and mandibular arches. The maxillary arch is part of the maxilla or the upper jaw, which contributes to forming the hard palate, the floor of the orbit, and the base of the nose. The curved, inferior margin of the maxillary bone that contains the upper teeth is the alveolar process of the maxilla. In contrast, the mandibular arch is part of the lower jaw, or mandible, which houses the lower teeth. The major muscles responsible for biting and chewing are connected to this area, particularly the ones arising from the zygomatic arch, which is different from the dental arches in question.
