6. The radius is distal

1. external, 2. paralel and distal, 3. proximal, 4. posterior, 5. anterior, 6. distal, 7. proximal.

Explanation:

1. The radius is paralel to the ulna in its external portion. It means it is located far from the body in an anatomical position, where the hands are with the palms facing forward.

2. The ribs are located parallel to the clavicle and descending towards the lower part of the body. Because they are moving away from the clavicle they are said to be distal to it.

3. The femur is proximal to the tibia, because it is located in the nearest portion of the "center of the body". It is attached to the hip. The tibia is attached to the femur, so tibia is distal to it.

4. The vertebral column is posterior to the sternum. Posterior, refers to something that is in the back or at the bottom in anatomical terminology. The vertebral column is in the back of the sternum.

5. The clavicle is anterior to the scapula. Anterior, refers to something that is in the front or at the top. The clavicle is in the front of the body and the scapula is on the back.

6. The radius is distal to the humerus. Distal, refers to "distance". It refers to sites that are located far from a specific area, almost always, the center of the body. In this case, the humerus is attached to the body first forming part of the joint of the shoulder; the radius is far from the shoulder, or the center of the body, so, it is located distal to the humerus.

7. The sternum is proximal to the ribs. Proximal, means closer to the center (trunk of the body) or the point of attachment to the body. The ribs are attached to it.
