Question

Quizplus · Accepted Answer

The external acoustic meatus is indeed a canal located in the temporal bone of the skull. The zygomatic arch consists of joined processes between the temporal and zygomatic bones (not the frontal bone as stated in option B). The nasal conchae are thin, curved bones located inside the nasal cavity (they do not form the nasal septum as stated in option C). The mastoid process is a bony protrusion located behind the ear, not anterior to it as stated in option D. The bridge of the nose is primarily formed by the nasal bones (not the frontal bone as stated in option E).
