1. Movement in Anatomical Terms

2. The Anatomical Position
Universal “starting point”
All joints are considered to be in a neutral position
No movement has occurred yet
Arms slightly to the side, palms up!
Standing erect, palms and feet facing forward

3. Planes
Fixed lines of reference along which the body is often divided or sectioned for viewing structures
By studying a region from sagittal, horizontal, and frontal planes of reference, a 3-D perspective can be obtained.

4. Planes
Sagittal: the plane that creates a right and a left side of the body passing from the front to the back
Horizontal: also called the transverse plane, creates a top and a bottom
Frontal: also called the lateral plane, creates a front and a back side as it passes from one side of the body to another

5. Anatomical Positions and Directions
Used for spatial relationships
Superior: refers to something that is above or higher than another structure
Inferior: refers to something that is below or lower than another structure

6. Anatomical Positions and Directions
Lateral: Refers to something farther away from the midline of the body
Medial: Refers to something closer to the midline of the body

7. Anatomical Positions and Directions
Anterior: Refers to a structure that is in front of another structure
Posterior: Refers to a structure that is behind another structure

8. Anatomical Positions and Directions
Proximal: means closer to the trunk
Distal: means farther away from the trunk
Dorsal: means top side of a structure (dorsal fin)
Plantar: the underside of the foot

9. Anatomical Positions and Directions
Prone: means lying face down
Supine: means lying face up
Afferent: directed toward a center
Efferent: directed away from a center
Central: situated or pertaining to a center
Peripheral: situated away from a center
Median: situated in the midline of a structure

10. Anatomical Positions and Directions
Intermediate: situated between median (middle) and lateral (side)
Deep: situated far beneath the surface
Superficial: situated near the surface

11. Fundamental Movements
Flexion: decreasing the angle formed by the bones of the joint
Extension: increasing the angle of the joint
Example: knee flexion vs. knee extension
Hyperextension: extreme or excessive straightening of a part

12. Fundamental Movements
Abduction: movement away from the midline of the body
Adduction: movement toward the midline of the body
Example: hip adduction vs. hip abduction

13. Fundamental Movements
Internal (Medial) Rotation: the anterior surface of the arm or leg rotates medially toward midline.
External (Lateral) Rotation: the anterior surface of the arm or leg rotates laterally away from the midline

14. Fundamental Movements
Circumduction: movement in 2 or 3 planes
At which joints is this movement possible?

15. Fundamental Movements
Pronation: turning the forearm toward the body
Supination: turning the forearm outward from the pronated position (hold a cup of soup)

16. Fundamental Movements
Dorsiflexion: bringing the toes towards the body
Plantar Flexion: pointing the toes away from the body

17. Injury Terms Abrasion: skins surface scraped away
Acute: recent or new injury; sudden onset
Atrophy: wasting away of tissue or an organ
Avulsion: tearing away of a part or a structure
Bursa: fluid filled sac

18. Injury Terms Calcification: deposits of calcium in an area
Chronic: injury with a long onset and long duration
Contraindicate: to advise against
Contusion: bruise
Crepitus: crackling sound
Cyanosis: blue discoloration

19. Injury Terms Dislocation: complete separation of two ends of a joint
Subluxation: partial or incomplete separation of a joint
Ecchymosis: bruising, blue color
Edema: swelling in the tissue
Effusion: swelling in the joint
Fracture: break in the bone

20. Injury Terms
Hematoma: collection of or swelling that is blood; blood tumor
Incision: straight cut; surgical cut
Indicate: advise the use of
Inflammation: body’s response to injury
Joint Laxity: Looseness in the joint
Laceration: jagged tear of the skin

21. Injury Terms Ligament: structure that connects bone to bone
Tendon: structure that connects muscle to bone
Modality: healing apparatus
Point Tenderness: pain produced when structure is palpated
Puncture wound: body part is pierced or stabbed by an object

22. Injury Terms Range of Motion: amount of movement allowed at the joint
Referred Pain: pain felt somewhere other than its origin
Sprain: stretching or tearing of ligaments
Strain: stretching or tearing of muscle/tendons
Valgus: position of a body part that is bent outward
Varus: position of a body part that is bent inward
