it depends on which joint it is.

Flexibility: Joints enable your body to move

Ball and socket joints: Are the most mobile type of joint in your body

Saddle joints: Enable you to grasp things

Explanations:

  • Ball and socket joints, like your hip and shoulder joints, are the most mobile type of joint in the human body. They allow you to swing your arms and legs in many different directions.
  • Ellipsoidal joints, such as the joint at the base of your index finger, allow bending and extending, rocking from side to side, but rotation is limited.
  • Gliding joints occur between the surfaces of two flat bones that are held together by ligaments. Some of the bones in your wrists and ankles move by gliding against each other.
  • Hinge joints, like in your knee and elbow, enable movement similar to the opening and closing of a hinged door.
  • The pivot joint in your neck allows you to turn your head from side to side.
  • The only saddle joints in your body are in your thumbs. The bones in a saddle joint can rock back and forth and from side to side, but they have limited rotation.
