  1. Movement and Directional Terms

  2. Flexion Vs. Extension • Flexion – • decreasing joint • Extension – • increasing joint • What plane do these movements take place in? • At which joints can F/E occur? • At which joints can hyperextension occur?

  3. Abduction Vs. Adduction • Abduction – • away from midline • Adduction – • towards midline • What plane do these movements take place in? • At which joints can Ab/Ad occur? • What is it called in the wrist, neck, and ankle?

  4. Internal Vs. External Rotation • Internal Rotation – • towards midline • External Rotation – • away from midline • Which joints can perform these movements? • What is it called in the neck? • Was is it called at the radioulnar joint?

  5. Anterior Vs. Posterior • Anterior – • front • Posterior – • back • Also refers to an ‘aspect’ of the body. • Nose is on the anterior aspect of the body. • My Quad muscle is to my hamstring muslces. • My tricep is to my bicep brachii. • My pectoralis major is anterior to my abs? • My trapezius is posterior to my glutes.

  6. Medial Vs. Lateral • Medial – • towards midline • Lateral – • away from midline • Aspect: • Arms are on the lateral aspect. • My fibula is to my tibia. • My belly button is to my hip bone. • My adductor longus is medial to my adductor brevis? • My left arm is lateral to my right arm?

  7. Inferior Vs. Superior • Inferior – • below • Superior – • above • My shoulders are to my hips. • My ankles are to my knees. • My right iliac crest is inferior to my left iliac crest? • My sternum is superior to my thoracic spine?

  8. Distal Vs. Proximal • **Only used for extremities, and rarely head.** • Distal – • further from trunk • Proximal – • closer to trunk • My wrist is to my elbow. • My hamstring is to my calf muscle. • My spleen is distal to my pancreas? • My eyes are proximal to my mouth?
