1. Biomechanics: Science concerned with the internal and external forces acting on the human body. 2. Superior: Positioned above point of reference 3. Inferior: Positioned below point of reference 4. Proximal: Positioned nearest the center of the body or point of reference 5. Distal: Positioned farthest from the center of the body or point of reference 6. Anterior: On front of the body 7. Posterior: On the back of the body 8. Medial: Positioned near the middle of the body 9. Lateral: Toward the outside of the body 10. Contralateral: Positioned the opposite side of the body 11. Ipsilateral: Positioned on the opposite side of the body 12. Anatomic Position: Position with the body erect 13. Sagittal Plane: Imaginary bisector that divides the body into left and right halves 14. Flexion: Bending movement in which the angle between two segments decreases 15. Extension: Straightening movement where the relative angle between two segments increases 16. Hyperextension: Extension of a joint beyond its normal limit or range 17. Frontal Plane: Imaginary bisector that divides the body into front and back halves 18. Abduction: Movement in the frontal plane towards the body 19. Adduction: Movement in the frontal plane away from the body 20. Transverse Plane: Imaginary bisector that divides the body into top and bottom halves. 21. Internal Rotation: Rotation of a joint towards the midline of the body 22. External Rotation: Rotation of a joint away from the midline of the body 23. Horizontal Abduction: Movement of the arm or thigh in the transverse plane from an anterior position to the lateral position 24. Horizontal Adduction: Movement of the arm or thigh in the transverse plane from the lateral position to the anterior position. 25. Scapular Retraction: Shoulder Blades move towards the middle 26: Scapular Protraction: Shoulder blades move away from the middle of the body 27. Scapular Depression: Scapula moves downward(inferior) 28. Scapular Elevation: Scapula moves upward(superior) 29: Essentric Muscle Action: Muscle develops tension while lengthening 30: Concentric Muscle Action: Exerting force greater than resistive force resulting in shortening of the muscle 31. Isometric Muscle Action: Muscle is exerting force equal to resistive force causing no change in the muscle 32. Force: Influence applied by one object to another 33. Length Tension Relationship: Resting length of a muscle and the tension it can produce 34. Force Couple: Two or more muscle groups working together to produce movement 35. Rotary Motion: Movement of the bones around a joint 36. Torque: A force that produces rotation 37. Motor Behavior: Motor response to internal and external stimuli 38. Motor Control: How the CNS(Central Nervous System) integrates internal and external sensory information with previous experience to produce a motor response 39. Motor Learning: Integration or motor control processes through practice and experience 40. Motor Development: Change in motor behavior over time 41. Muscle Synergies: Group of muscles recruited by the CNS to work together for movement 42. Proprioception: Cumulative sensory input from all mechanoreceptors that sense position and movement 43. Sensorimotor Integration: Cooperation of the Nervous and Muscular System to provide movement 44. Feedback: Use of sensory information and sensorimotor integration to help in motor learning 45. Internal Feedback: Body uses sensory information to reactively monitor movement 46. External Feedback: Body uses external information provided by outside source.
