Question

Go through some of your body's joints and determine which of the following pairs of movements are relevant/possible at each. (Be sure you can demonstrate each of the following movements at an appropriate joint.)

Elevation and Depression Lateral Flexion Flexion and Extension Hyperextension Abduction and Adduction Protraction and Retraction Medial and Lateral Rotation Circumduction Supination and Pronation Radial and ulnar Deviation Dorsiflexion and Plantar Flexion Inversion and Eversion Opposition

Answer 1

• FLEXION & EXTENSION takes place at the shoulder,hip,elbow,knee,wrist,metacarpophalangeal,metatarsophalangeal and interphalangeal joints.

HYPER EXTENSION is the excessive extension of a joint more than the normal range of motion,resulting in injury.

LATERAL FLEXION is the bending of the body to the left or right side.

• ADDUCTION,ABDUCTION & CIRCUMDUCTION could be done at the shoulder,hip,wrist,metacarpophalangeal and metatarsophalangeal joints

• SUPINATION & PRONATION,RADIAL & ULNAR DEVIATION are the movements of the forearm/wrist.

• DORSIFLEXION & PLANTAR FLEXION are the movements at the ankle joint.

• PROTRACTION &RETRACTION,DEPRESSION & ELEVATION movements are of the scapula or mandible.

• OPPOSITION is the movement of the thumb.

• MEDIAL & LATERAL ROTATION involves movement of the limbs.

• INVERSION & EVERSION are the movements involving tarsal bones of the posterior foot.
