Which carpal bone is commonly called the navicular bone?

Explanation:
The term navicular is used for a boat-shaped bone, and among the carpal bones the one that fits that shape is the scaphoid. The scaphoid sits on the thumb side of the wrist and has a boat-like form, which is why it’s commonly referred to as the navicular bone in the carpus. The other options aren’t carpal bones or aren’t described as navicular: the scapula is the shoulder blade, the sternum is the breastbone, and silicosis is a lung disease. So, the scaphoid is the bone people mean when they say the navicular in the wrist.
