The mandible, or lower jaw, is formed from the mandibular pharyngeal arch during human development. The mandibular pharyngeal arch is one of the first structures that develop in the embryo, contributing to various structures of the face and neck. It plays a crucial role in the formation of both the mandible and several other vital anatomical features associated with the jaw, such as the muscles that control movement of the jaw and certain nerves that facilitate sensation in the facial region.

The maxillary arch is involved in forming the upper jaw, but it does not contribute to the mandible itself. The zygomatic process pertains to the formation of the cheekbone and does not play a role in mandible development. Similarly, the palatine structure is related to the formation of the hard palate in the mouth, not to the mandible. Understanding these relationships is essential for comprehending embryological development and the anatomy of the human face.
