Dental Anatomy: Understanding the Human Mouth Structure

What are the two sections of the human mouth called?

a) Maxillary and mandibular arches

b) Buccal and lingual arches

c) Mesial and distal arches

d) Labial and occlusal arches

Answer:

The two sections of the human mouth are known as the maxillary and mandibular arches.

The human mouth is divided into two sections, or arches, known as the maxillary and mandibular arches. The maxillary arch is part of the upper jaw, specifically the maxilla. It helps form the hard palate, the floor of the orbit, and the base of the nose. The alveolar process of the maxilla, located on the inferior margin of the maxillary bone, contains the upper teeth.

On the other hand, the mandibular arch is part of the lower jaw, known as the mandible. This section houses the lower teeth and plays a crucial role in biting and chewing. The major muscles responsible for these functions are connected to the mandibular arch, particularly those originating from the zygomatic arch.
