Flexion | the angle between articulating bones is decreased and flexion occurs in the median plane about the horizontal axis. Muscles responsible for flexion are called flexors. |
Extension | The angle joint is increased and extension occurs in the median plane about the horizontal axis. Muscles responsible for extensions are known as extensors. |
Abduction | This movemwent of a body part away from an imaginary midline of the body. it occurs in the frontal plane. |
Adduction | This movement of a body towards an imaginary midline of the body. It can occur in the frontal and horizontal planes. |
Rotation | Rotation occurs when a bone turns on its own within a joint. Rotation towards the bodys midline is known as medial or internal rotation; rotation away from the midline is known as lateral or external rotation. |
Circumduction | Circumduction occurs when a limb moves ina circular fashsion and is generally only possible at ball and sockect joints because flexion, extension, abduction and adduction are required. This occurs in the median and frontal planes. |
pronation | pronation occurs when the forearm is rotated while the palm of the hand faces downwards. when this occurs, the radius and the ulna are crossed over each other. |
supination | Supination occurs when the forearm is rotated,turning from the hand palm down to palm up, so the radius and ulna lie parallel to each other and are uncrossed. |
Plantarflexion | Plantarflexion Occurs at the ankle when the toes are pointed downwards and the heel is raised. this occurs in the median plane about a horizontal axis. |
