Question

which of the following movements is a good example of flexion? group of answer choices turning the hand palm upward opening the mouth moving the hand toward the shoulder spreading the fingers extreme bending of the head backwards

Answer 1

Flexion is the decrease in the angle between the bones of a joint, and 'moving the hand toward the shoulder' exemplifies flexion in the elbow joint.

Step-by-step explanation:

The concept in question relates to the movements of the body, specifically flexion, and is a critical part of understanding human anatomy and physiology. Flexion refers to a decrease in the angle between the bones of a joint. In the list of movements provided, the such movement that most accurately exemplifies flexion is "moving the hand toward the shoulder". This action decreases the angle between the forearm and the upper arm at the elbow joint - a classic example of flexion. Alternatives such as turning the hand palm upward (supination) and opening the mouth (depression of the mandible) represent different types of joint movements but not flexion. Similarly, spreading the fingers (abduction) and extreme bending of the head backwards (hyperextension) are not examples of flexion either.
