Why do women typically tend to have slightly greater stability than men?

Women are shorter than men, and shorter people are more stable.

Men have more muscle mass in their lower bodies that makes them stiff and less stable.

Women have lower centers of gravity, and lower centers of gravity provide more stability.

The increased muscle mass in their upper bodies makes their centers of gravity difficult to find.

Range of motion is the distance an object can travel when separated from another object.

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

The contours of the two bones allow for maximum movement.

The even planes of the bones allow full rotation.

The two matching surfaces allow for movement in multiple directions.

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

Participating in __________ can improve flexibility.

yoga

pilates

swimming

all of the above

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

The average ranges of motion of joints are not known.

Each joint has a different range of motion.

Range of motion can change rapidly in a joint.

none of the above

The center of gravity does not contribute to individual stability.

Which type of joint allows rotation of one bone around another like when rotating the head?
