Question

What is the body position or direction for a bending motion that decreases the angle between adjoining bones?

1) Flexion
2) Extension
3) Abduction
4) Adduction

Answer 1

The bending motion that decreases the angle between adjoining bones is called flexion. This motion is the opposite of extension, which increases the angle, straightening the joint.

Step-by-step explanation:

The body position or direction for a bending motion that decreases the angle between adjoining bones is known as flexion. This movement involves a decrease in the angle between the bones of a joint, similar to bending the elbow or the wrist to move the hand toward the forearm. In contrast, extension is the increase of the angle between the bones, which straightens the joint. Abduction is when a bone moves away from the midline of the body, while adduction is the movement of a bone toward the midline. Therefore, the correct answer to the student's question is 1) Flexion.
