scaphoid bone
Noun: * The largest wrist bone on the thumb side: The scaphoid bone is one of the eight small carpal bones that make up the wrist. It is located near the base of the thumb and is the largest bone in the row of carpal bones closest to the forearm (the proximal row). Its name comes from the Greek word for "boat-shaped," describing its elongated, curved form.
The term "scaphoid bone" is used specifically in anatomical, medical, and clinical contexts to identify this particular wrist bone. It is most commonly discussed in relation to injuries or conditions affecting the wrist. * The surgeon carefully examined the X-ray to assess the fracture in the scaphoid bone. * A fall onto an outstretched hand is a common mechanism for injuring the scaphoid bone. * The scaphoid bone articulates with the radius, lunate, trapezium, trapezoid, and capitate bones.
