Which bone contains the external auditory meatus?

• A. Frontal bone
• B. Parietal bone
• C. Temporal bone
• D. Occipital bone

Answer: (C)

The external auditory meatus, which is the ear canal leading to the eardrum, is uniquely found within the temporal bone. This bone is situated at the side and base of the skull and houses the structures associated with the inner and middle ear, including the auditory meatus. The temporal bone's anatomical features are specifically designed to support the auditory system's function. Its location and structure allow for effective sound transmission and protection of the delicate components of the ear. This makes it the only bone listed that possesses the external auditory meatus, thereby making it the correct answer. Understanding the role of the temporal bone in hearing anatomy highlights its significance in the overall structure of the skull.
