The joints of rotation of a limit are the points where the function changes direction or behavior. These points are typically where the function is not differentiable or where there is a cusp, corner, or vertical tangent. Joints of rotation are important for understanding the behavior of a function near its limits.
Footballers frequently use their hip, knee, and ankle joints to perform movements such as running, jumping, kicking, and changing direction. These movements require a combination of flexion, extension, abduction, adduction, and rotation at these joints to carry out skills and maneuvers on the field.
Pivotal joints allow for rotation around a central axis, such as the neck and forearm, enabling movements like rotation and turning. These joints are crucial for activities such as nodding the head, twisting the forearm, or shaking the head.
Flexion is when you flex your arms, thighs, and other muscles. Rotation is when you rotate your joints, bending or twisting you muscles.
The radioulnar joints are the joints that connect the radius and ulna bones in the forearm. These joints allow for rotational movements of the forearm, specifically pronation (rotation of the forearm to face downwards) and supination (rotation of the forearm to face upwards).
Some examples of rotating joints in the human body include the shoulder joint, hip joint, and wrist joint. These joints allow for movements in multiple planes, such as flexion, extension, adduction, abduction, and rotation. Rotation at these joints is essential for tasks requiring twisting or turning movements.
Ball and socket joints can be found in the human body at the hip and shoulder joints. They allow for a wide range of motion in multiple directions, including rotation.
The rotation of the atlas on the axis (first two vertebrae)
Shoulder joints have the greatest mobility among the options listed. They have a wider range of motion compared to hip, elbow, knee, and wrist joints, allowing for movements in multiple directions such as flexion, extension, abduction, adduction, and rotation.

Non-axial joints are joints where the bones have limited movement mainly in a plane such as gliding joints in the wrists and ankles. These joints allow for simple movement without rotation, like sliding or gliding movements. Non-axial joints provide stability and support for the body.
At the thoracic vertebrae, joints include the intervertebral joints between the individual vertebrae, the costovertebral joints where the ribs articulate with the vertebrae, and the costotransverse joints where the ribs articulate with the transverse processes of the thoracic vertebrae.
