Which hand bone is navicular bone?

Explanation:
In the hand, the navicular bone refers to the scaphoid, a boat-shaped carpal bone on the thumb side of the proximal row. It sits between the radius and the other carpal bones and helps form the radiocarpal joint. The capitate is the large central bone in the distal row, the lunate is another proximal row bone located medial to the scaphoid, and the trapezium is a distal carpal bone at the base of the thumb. Recognizing that the navicular is the scaphoid supports understanding of wrist anatomy and common fractures from falls on an outstretched hand.
