In a human arm, the phalanges are ____________ to the humerus.

In a human arm, the phalanges are ____________ to the humerus.

A. Proximal

B. Distal

C. Superficial

D. Superior

Answer:- B. Distal

The phalanges are the bones of fingers and toes. They are the furthest bones from the central core of the body in upper and lower limbs.

The humerus is a long bone of the upper arm. Its proximally forms the shoulder joint and distally, it forms the elbow joint. The phalanges of the hand are joined to metacarpals bones that join in turn, with other carpal bones at wrist end into radius and ulna bone ends located on forearm hence attaching distally right up to humerus.

The phalanges being lower in the limb than the humerus are therefore distally situated to it. “Proximal” means closer to the core, while “distal” is far away. The phalanges are more distal structures compared to the humerus, which is a little proximal and near the shoulder joint.

Therefore, the phalanges are located more distally on a human’s arm in anatomical position because they appear further away from the central core of limb (Quizlet, Inc., 2024). This distal connection permits complex movements of the fingers and hand to be manipulated from a stable foundation, which is facilitated by its contact with the humerus bone.
