Final answer:
The AP axial projection-lordotic position is a radiographic technique used to visualize the cervical vertebrae by creating a lordotic curve in the lower back.
Step-by-step explanation:
The AP axial projection-lordotic position is a radiographic technique used to visualize the cervical vertebrae. In this position, the patient is asked to lean back as far as possible, creating a lordotic or exaggerated swayback curve in the lower back. This helps to separate the cervical vertebrae and improve the visibility of the intervertebral spaces. The resulting x-ray image allows for the evaluation of conditions such as degenerative changes, fractures, or dislocations in the cervical spine.
