- A.
Petrous part of temporal bone
- B.
Squamous part of temporal bone
- C.
Internal auditory meatus
- D.
External auditory meatus
Correct Answer
A. Petrous part of temporal boneExplanation
The red arrow refers to the petrous part of the temporal bone. The petrous part is the densest and most durable portion of the temporal bone, located deep within the skull. It houses important structures such as the middle and inner ear, including the cochlea and semicircular canals. The petrous part also contains the internal auditory meatus, which is a canal that transmits the facial and vestibulocochlear nerves.
