Final answer:
Flexibility is the ability to flex, extend, or circumduct joints through their full range of motion. It involves various types of movements like flexion, extension, hyperextension, abduction, adduction, and circumduction. The shoulder joint allows for the greatest range of motion.
Step-by-step explanation:
Flexibility refers to the ability to flex, extend, or circumduct the joints through their full intended range of motion. It involves various types of movements such as flexion, extension, hyperextension, abduction, adduction, and circumduction. For example, bending the forearm at the elbow is an example of flexion, while straightening a limb after flexion is an example of extension. The shoulder joint allows for the greatest range of motion, while carpal bones are more stable.
