Types of movement
Adduction (Ball and socket)
Movement of a bone or limb towards the mid line of the body.
Rotation (Ball and socket)
A circular movement around a joint.
Abduction (Ball and socket)
Movement of a bone or limb away from the mid line of the body
Plantar flexion (Hinge)
Movement at the ankle joint that points the toes and increases the angle at the ankle joint.
Flexion (Hinge)
Decrease in the angle of bones at a joint.
Dorsiflexion (Hinge)
Movement at the ankle joint that flexes the foot upwards and decreases the angle at the ankle joint.
Extension (Hinge)
Increase in the angle of bones at a joint.
How do joints help us move?
Hinge at the ankle enables flexion and dorsiflexion.
Ball and socket joints enable rotation and adduction and abduction
Hinge can only enable flexion and extension
