Skeletal system - EdexcelTypes of joint movement in the skeletal system

The skeleton is the central structure of the body and is made up of bones, joints and cartilage. The skeleton provides the framework for muscles and gives the body its defined human shape.

Types of joint movement in the skeletal system

The different types of movement that are permitted at each joint are described below.

Flexion 鈥 bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl.

Flexion - man performing a biceps curl with a dumbbell

Extension 鈥 straightening a joint. This occurs when the angle of a joint increases, for example, at the elbow when putting a shot.

Extension - man putting a shot

Abduction 鈥 movement away from the midline of the body. This occurs at the hip and shoulder joints during a jumping jack movement.

Abduction and adduction - woman performing a jumping jack or star jump

Adduction 鈥 movement towards the midline of the body. This occurs at the hip and shoulder, returning the arms and legs back to their original position from a jumping jack movement.

Circumduction 鈥 this is where the limb moves in a circle. This occurs at the shoulder joint during an overarm tennis serve.

Circumduction - man serving overarm in tennis

Rotation 鈥 this is where the limb moves in a circular movement around a fixed joint towards or away from the midline of the body. This occurs in the hip in golf while performing a drive shot.

Rotation - man performing a shot in golf

Plantar flexion 鈥 pointing the toes 鈥 this movement only occurs at the ankle, for example, pointing the toes in ballet.

Plantar flexion - the toes are pointed in a ballet movement

Dorsiflexion 鈥 the foot moves towards the shin as if you are pulling your toes up. This movement only occurs at the ankle.

Dorsiflexion - the toes are pulled up in a stretch

The table summarises the body locations and types of movements associated with each type of joint.
