Which activity involves neck extension?

Which activity involves neck extension?

• A. Nodding yes
• B. Shaking hands
• C. Looking down at a book on the lap
• D. Looking up to an overhead cabinet

Answer: (D)

Neck extension is the movement of tilting the head backward to look upward. Looking up to an overhead cabinet requires that backward tilt of the head, so it’s the clearest example of neck extension. Nodding yes mostly uses bending the neck forward (flexion) with the head returning upright, not a sustained extension. Looking down at a book is clearly neck flexion. Shaking hands involves the arms and shoulders, not the neck movement in question.
