Question

The forearm consists of the:

radius and ulna
radius and humerus
ulna and humerus
humerus and carpus

Answer 1

The forearm is comprised of the radius and ulna, which are responsible for its range of movement. The humerus connects at the elbow but is considered the bone of the upper arm, not the forearm. Wrist bones, such as the carpus, are also not part of the forearm structure.

Step-by-step explanation:

The Forearm Anatomy

The forearm consists of two bones: the radius and the ulna. These bones are critical for the movement and support of the forearm. The radius is located on the lateral (thumb) side of the forearm and the ulna is on the medial (pinky-finger side). Unlike the humerus, which is the bone of the upper arm, the radius and ulna make up the skeletal structure of the forearm, allowing for various movements such as flexion, extension, pronation, and supination.

The humerus articulates with the scapula at the shoulder and with the forearm at the elbow, but it is not a part of the forearm. Bones like the carpus, which consists of eight bones, form parts of the wrist and are not part of the forearm either.

Answer 2

Radius and Ulna.

Those are the long bones that together form the forearm.

The external bone is the radius, and the inside bone is the ulna, they are joint by its extremes.

The humerus is the bone that forms the arm.

Carpus is a conjunction of bones that form the wrist.
