The bones of the hand articulate distally with the:
(a) Carpal bones
(b) Ulna and radius
(c) Metacarpals
(d) Phalanges

검증된 단계별 안내

Step 1: Understand the anatomy of the hand bones. The hand consists of three main groups of bones: the carpal bones (wrist bones), the metacarpals (bones of the palm), and the phalanges (finger bones).

Step 2: Identify the direction 'distally' in anatomical terms. 'Distal' means farther from the point of attachment or origin, so the bones that articulate distally with the hand bones are those located further along the limb.

Step 3: Recognize that the metacarpal bones articulate proximally with the carpal bones and distally with the phalanges.

Step 4: Since the question asks which bones articulate distally with the bones of the hand, determine which bones lie beyond the metacarpals in the distal direction.

Step 5: Conclude that the phalanges are the bones that articulate distally with the metacarpals, and thus with the bones of the hand distally.

Anatomy of the Hand Bones

The hand consists of three main groups of bones: the carpal bones (wrist), metacarpals (palm), and phalanges (fingers). Understanding their arrangement is essential to identify how they articulate or connect with each other.

Articulation and Joint Connections

Articulation refers to the connection between bones at joints. Knowing which bones connect distally (farther from the body's center) helps determine the correct bone relationships in the hand.

Distal and Proximal Terminology

Distal means farther from the point of attachment or origin, while proximal means closer. Recognizing these terms clarifies which bones lie closer or farther along the hand's structure.
