Answer to Question 1

underexposure with noise

Rationale: An S value represents the average exposure value for the part. An S value that is above the specified range indicates underexposure. Extreme underexposure will result in a mottled or noisy imaging.

Answer to Question 2

the superior and inferior vertebral notches

Rationale: Above and below each pedicle exists a notch. The superior and inferior vertebral notches align together in the column and form the intervertebral foramina.
