Which bone contains the mastoid air cells?

  1. Frontal Bone

  2. Temporal Bone

  3. Parietal Bone

  4. Occipital Bone

The correct answer is: Temporal Bone

The temporal bone is notably the bone that houses the mastoid air cells. These air cells are found in the mastoid process, which is a prominent feature of the temporal bone situated just behind the ear. Mastoid air cells are small, interconnected cavities that play a role in the body's respiratory system and help with pressure regulation in the middle ear. The presence of these air cells is essential for various auditory functions and can also be relevant in clinical settings for conditions such as mastoiditis, an infection of the mastoid air cells. Understanding the anatomy of the temporal bone, including the mastoid process and associated air cells, is fundamental for radiography, particularly in imaging the head and neck regions.
