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 boneB Frontal boneC Facial bonesD Basal foramina

Answer 1

Occipital bone.

Step-by-step explanation:

The AP axial projection helps in the projection of the anterior structures of the frontal and the facial bones (Towne method) of skull. The orbitomeatal line is a positional line used for the skull radiography.

The Towne method of skull as the CR directed 30 degrees to the orbitomeatal line (OML) is used to demostrate the occipital bones. This bone is located at the base of the cranium.

Thus, the correct answer is option (A).
