What muscle arises from arch 3?

Stylopharyngeus
Mylohyoid
Tensor tympani
Masseter

The correct answer is: Stylopharyngeus

Arch 3 is one of the six specializations of head and neck skeletal muscles that arise from pharyngeal arches during embryonic development. Other pharyngeal arch muscles include muscles of mastication, facial expression, and those used for tongue movement and swallowing. Out of the four choices, only the stylopharyngeus muscle arises from arch 3. Options B, C, and D correspond to muscles that arise from other pharyngeal arches, making them incorrect choices for this question.
