On which bone do we find the mastoid process?
Occipital.
Sphenoid.
Frontal.
Temporal.
The Correct Answer is D
The mastoid process is a bony projection of the temporal bone at the posterior base of the skull.
It allows the attachment of muscles such as the sternocleidomastoid and splenius capitis.
It also contains air-filled spaces called the mastoid air cells.
Choice A is incorrect because the occipital bone forms the back and base of the skull and does not have a mastoid process.
Choice B is incorrect because the sphenoid bone is a butterfly-shaped bone at the base of the skull that does not have a mastoid process.
Choice C is incorrect because the frontal bone forms the forehead and the upper part of the eye sockets and does not have a mastoid process.
