Arch 2 is also called?

Hyoid arch
Mandibular arch
Palatine arch
Zygomatic arch

The correct answer is: Hyoid arch

Arch 2 is also called the hyoid arch because it develops into the hyoid bone, which connects the tongue to the larynx. The other options are incorrect because - Mandibular arch (B) develops into the lower jaw bone, or mandible. - Palatine arch (C) is also known as the hard palate and forms the roof of the mouth. - Zygomatic arch (D) is the temporal bone that forms the cheekbone. While these structures are important in the head and neck, they are not specifically related to Arch 2 and therefore are not the correct answer.
