Anatomical Positions and Movements

1. Anatomical Positions and Movements

2. Types of Movements • The body can move in many different ways, each bone’s ability to move depends on the muscle attached and the type of joint. • Each movement has an opposite movement

3. Types of Movements (p14-15) • Flexion – bending • Extension – straightening • Adduction – Body part moves toward midline of body • Abduction – Body part moves away from the midline of the body • Rotation – Body part moves around its axis • Lateral – move outwards • Medial – Move inwards

4. More Movements • Circumduction – body part moved in a cone shape • Supination – rotate thumb in • Pronation – rotate thumb out • Eversion – Rotation of the sole outward • Inversion – Rotation of the sole inward

5. More Movements • Dorsi Flexion – Raising toes up • Plantar Flexion – pointing toes down • Elevation – shrugging shoulders • Depression – shoulders back down • Check out the pictures on pages 14 and 15 – actually try these movements to improve your understanding of them

6. Movement – Muscles and Bones! • For a movement to occur there must be a muscle between two bones • The point where the muscle attaches to the moving bone is called insertion • The point where the muscle attaches to the non-moving bone is called the origin

7. Movement – Muscles and Bones! • Muscles work as a team! • The muscle causing the action is known as the agonist • The muscle that does the opposite to the agonist to allow the agonist to work is called the antagonist • Eg. Bicep Curl
