The type of joint that allows a twisting or rotating movement is the pivot joint.

Quick Scoop

In basic biology and anatomy, different joints allow different kinds of movement. The specific joint that lets one bone rotate around another in a twisting motion is called a pivot joint.

What a pivot joint does

  • A pivot joint allows rotational movement around a single axis, which is felt as a twist or turn rather than a bend.
  • One bone is shaped like a cylinder (or peg) that rotates inside a ring formed by another bone and ligaments, creating that twisting motion.

Everyday body examples

  • Neck: The joint between the first two cervical vertebrae (atlas and axis) is a pivot joint that lets you turn your head side to side, like shaking your head “no”.
  • Forearm: The proximal radioulnar joint between the radius and ulna lets you twist your forearm to turn your palm up and down.

How it differs from other joints

  • Hinge joints (like the elbow and knee) mainly bend and straighten; they do not twist in a rotary way.
  • Ball-and-socket joints (like the shoulder and hip) allow wide-ranging movement, including rotation, but when a question asks “Which type of joint twists?”, the expected single best answer is the pivot joint.

TL;DR: When a question asks “Which type of joint twists?”, the correct answer is: pivot joint.
