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.

Correct Answer is ["condylar process of the mandible"]
Explanation
The mandible condylar process is a bony projection located at the posterior aspect of the mandible, which is the lower jawbone.
It is a rounded, knob-like structure that articulates with the temporal bone of the skull, forming the temporomandibular joint (TMJ).
The condylar process allows for movements of the mandible, including opening and closing the mouth and chewing food.
The shape and position of the condylar process can affect the function of the TMJ and can contribute to conditions such as TMJ disorders.
