Solution
The movements possible about the longitudinal axis at the shoulder are medial and lateral rotation only. This is because the longitudinal axis runs lengthwise or vertically down the body, and movements around this axis involve rotation towards the midline (medial rotation) or away from the midline (lateral rotation). Other movements such as abduction/adduction and flexion/extension occur around different axes.
