Which wrist bone is also known as the navicular?

• A. Ulna
• B. Scaphoid Bone
• C. Sacrum
• D. Patella

Answer: (B)

The wrist bone known as navicular is the scaphoid. The scaphoid is the boat-shaped carpal bone on the thumb side of the wrist that articulates with the radius. The name navicular comes from its boat-like shape, a naming choice historically used in anatomy. The other options are not wrist bones: the ulna is a forearm bone, the sacrum sits in the spine/pelvis, and the patella is the kneecap.
