Stability & Range Of Motion Quiz

Which of the following BEST explains why stability is an important skill for athletes?

Which of the following statements BEST explains why ball-and-socket joints have the greatest range of motion?

Why does range of motion need to be measured separately for each joint?

Which of the following terms describes the straightening of a joint, rather than the bending?

The carpal bones in the hands are an example of __________.

Explain the difference between a joint's possible range of motion and its actual range of motion.

Without good stability, athletes are too clumsy to perform well.
0%
Each type of joint has a possible range of motion associated with it. This possible range of motion depends upon the type of joint it is, rather than the characteristics of the individual who possesses this joint. A joint's actual range of motion, however, is dependent upon the fitness levels of the individual. Since the possible range of motion is the theoretical maximal range of motion, the actual range of motion will always be less.

The cup shape of the socket allows for nearly circular motion.

Unlike fixed joints or cartilaginous joints, where the bones are connected by either connective tissue or cartilage, the bones in synovial joints are not directly joined by anything, which allows for a much greater range of motion.

How are balance and stability different concepts?

0%
If excess muscle is too bulky it can interfere with the motion of a joint, which means that too much muscle strength can reduce a joint's range of motion and can actually reduce flexibility.
0%
Extension straightens a joint, and hyperextension bends it but in the opposite direction from flexion.
0%
Women generally have a lower center of gravity than men, which contributes to greater stability. Men generally have more muscle mass in their upper arms and bodies, which raises their center of gravity and can make them less stable on their feet.
0%
Balance is the ability to maintain equilibrium by neutralizing the forces that disturb it. Stability, meanwhile, is the ability to maintain balance while participating in actions that are likely to upset balance. Standing on one leg for several minutes demonstrates good balance, while playing in a vigorous soccer game without tripping or falling demonstrates good stability.

Participating in __________ can improve flexibility.

Which of the following BEST describes a body in equilibrium?

Explain why synovial joints have greater flexibility than fixed and cartilaginous joint.
