Moving a body part forward relative to the body is called which term?

• A. Protraction
• B. Retraction
• C. Elevation
• D. Depression

Answer: (A)

Moving a body part forward relative to the body is protraction. This term describes anterior displacement, typically in the horizontal plane. It’s the opposite of retraction, which pulls a part backward toward the spine. Elevation and depression are vertical movements (lifting up and lowering down), not forward movement. For example, jutting the lower jaw forward or pushing the shoulders forward as you reach for something are protraction movements of the jaw and scapula, respectively. The key idea is forward, anterior movement of the part.
