In a lateral cervical radiograph, atlas listings describe two aspects of position: whether the atlas sits anterior or posterior to the skull base, and whether that position is above or below a reference line. anatomically, the atlas sits below the skull, so a superior (above) relation isn’t possible on this view. That means the only valid vertical component is inferior, leaving two possible combinations: anterior inferior or posterior inferior. Since the lateral view lets you see forward or backward shift (anterior vs posterior) and the atlas must be inferior, the two workable listings are anterior inferior and posterior inferior. The other pairings would require a superior relation, which doesn’t occur in this view. So the correct option reflects AI or PI.

In an APOM view, the occiput is described using two directions to capture how the skull sits relative to the atlas on both sides. You assess which side of the occiput is shifted and whether that shift is toward the front (anterior) or back (posterior). That creates four regional descriptors: left anterior, left posterior, right anterior, right posterior. This two-axis, quadrant-style labeling lets you map rotational and tilt components at the craniovertebral junction, which is how the occiput often deviates in this projection. Other descriptions that use only a single axis (like just superior/inferior, or just medial/lateral) don’t fully describe the two-dimensional nature of occipital alignment seen on APOM, so the four-quadrant left/right with anterior/posterior on each side best fits what APOM is documenting.

Static palpation looks at tissue qualities as the area sits at rest. You’re evaluating how the tissue feels in a resting state: the skin’s condition and texture, the presence of swelling (edema), and tenderness that is detected through light touch. These characteristics reflect the static state of the tissues. Temperature, by contrast, is a dynamic physiologic sign. Warmth or coolness can change with inflammation, time of day, environmental conditions, and other factors, so it isn’t a fixed tissue property you assess in a purely resting state. Because of that variability, temperature isn’t categorized as a static palpation component, even though you may notice it during an examination.

The probe width should be oriented parallel to outward because that direction aligns with the main plane in which the thoracolumbar segments glide during assessment. Running the probe this way keeps contact along the joint surfaces and surrounding tissues in their natural sliding direction, making it easier to feel subtle differences in motion or tissue tension from one segment to the next. If you aimed perpendicularly to the midline or toward the spine, you’d cross the joint plane awkwardly and lose sensitivity; a diagonal orientation to the bed would misalign with the actual glide path and distort what you’re feeling.
