Final answer:
The superficial portion of the masseter originates from the maxillary process of the zygomatic bone and the inferior border of the zygomatic arch, while the deep portion originates from the zygomatic arch itself. These origin points allow the masseter muscle to effectively elevate the mandible during chewing.
Step-by-step explanation:
The correct statement that accurately describes the origin points of the masseter muscle is: B. The superficial portion originates from the maxillary process of the zygomatic bone and the inferior border of the zygomatic arch, whereas the deep portion originates from the zygomatic arch. This is because the masseter muscle is one of the muscles involved in chewing and requires strong leverage, which is provided by its origin points on the zygomatic bone and arch.
The masseter is a facial muscle and its main function is to elevate the mandible (lower jaw). The superficial part of the masseter originates on the anterior aspect of the zygomatic arch and the maxillary process of the zygomatic bone. It then inserts into the angle and lateral surface of the mandibular ramus. On the other hand, the deep part of the masseter originates from the medial surface of the zygomatic arch and extends to the upper portion of the ramus of the mandible, including the coronoid process.
