  18. An imaginary bisector that divides the body into top and bottom halves
    Transverse plane
  19. Rotation of a joint toward the middle of the body
    Internal rotation
  20. Rotation of a joint away from the middle of the body
    External Rotation
  21. Movements in the sagittal plane include
    _________ and ______.
    Flexion, extension
  22. Movements in the frontal plane are ________ and ______.
    Adduction and abduction
  23. Movements in the transverse plane are _____ and ____ .

  29. Moving in the same direction as the resistance
    Decelerates or reduces force
    lengthening of the muscle
  30. No visible movement with or against resistance
    Dynamically stabilizes force
    Muscle maintains a certain length
  31. Moving in the opposite direction of force
    Accelerates or produces force
    Shortening of the muscle
  32. Image Upload 6
    rhomboid muscle
  33. Image Upload 7
    Sartorius muscle
  34. Image Upload 8
    Anterior hip muscles
  35. An interaction between two entities or bodies that result in either the acceleration or deceleration of an object.
  36. The length at which a muscle can produce the greatest force. There is an optimal length at which the actin and myosin filaments in the sarcomere have the greatest degree of overlap results in the potential for maximal force production.
    Length-tension relationship
  37. The ability of muscles to produce force with increasing velocity. As the velocity of a concentric muscle contreaction increases its ability to produce force decreases. Conversely as the velocity of muscle actions increases with eccentric muscle action , the ability to develop force increases.
    Force-velocity curve
  38. The synergistic action of muscles to produce movement around a joint. All muscles working together for the production of proper movement are said to be working this.
  39. To ensure that the kinetic chain moves in the right manner, it must exhibit proper _______ relationships. This can only happen if the muscles are at the right ___________ relationships and the joints have proper __________ (joint motion).
    • Force Couple
    • Length tension
    • arthrokinematics
  40. Movement of the bones and joints. The levers (bones) rotate arount the axis (joints).
    rotary motion
  41. Turning effect of the joint
  42. >Is concerned with those neural structures that are involved with motor behavior and how they produce movement.
    >The study of posture and movements and the involved structures and mechanisms that the central nervous system uses to assimilate and integrate the sensory information with previous experiences.
    Motor control
  43. Groups of muscles that are recruited by the central nervous system to provide movement
  44. % of population that experiences low back pain

  46. The ability of the nervous system to gather and interpret sensory information and select and execute the proper motor response.
    Sensorimotor integration
  47. repeated practice of motor control processes, which lead to a change in the ability to produce complex movements.
    motor learning
  48. the use of sensory information and sensorimotor integration to help the kinetic chain in motor learning
  49. The process whereby sensory information is used by the body via length-tension relationships (posture), force-couple relationships, and arthrokinematics to reactively monitor movement and the environment.
