Question

In the Ap axial projection (Towne method) of the skull, with the CR directed 30 degrees caudad to the orbitomeatal line (OML) and passing midway between the external auditory meati, which of the following is best demonstrated?
A) Occipital bone
B) Frontal bone
C) Facial bone
D) Basal formina

Answer 1

Answer:

A) Occipital bone

Explanation:

Based on the scenario being described it can be said that the structure best demonstrated would be the occipital bone. This is a bone that forms in the base of the skull towards the back and around the spinal cord. Since the AP axial position projects the anterior structures downward, then it would allow for the occipital bone to be easily viewed without special equipment.
