chapter 01 week 1 lecture 2

  1. 1. PTHA 1513 FUNCTIONAL ANATOMY Week 1: Lecture 1 Elaine Wilson, PT 1
  2. 2. Today’s Theme Song  2 Welcome to the Sprin
  3. 3. Goals for Today 3  Review the course syllabus  Define commonly used anatomic and kinesiologic terminolgy  Describe common movements of the body  Analyze the planes of motion and axes of rotation for common motions
  4. 4. Syllabus Review 4
  5. 5. Expectations for Functional Anatomy5
  6. 6. CHAPTER 1 Basic Principles of Kinesiology
  7. 7. Kinematics 7  Translation  Rectilinear motion (straight line)  Curvilinear motion (curved line)  Rotation (movement of body about an axis)  Active movements  e.g., flexing an arm over the head  Passive movements  e.g., resistance of a stretched ligament Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  8. 8. Kinesiology Terminology 8  Anterior: toward the front of the body  Posterior: toward the back of the body  Midline: an imaginary line that courses vertically through the center of the body  Medial: toward the midline of the body  Lateral: away from the midline of the body  Superior: above, or toward the head Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  9. 9. Kinesiology Terminology – cont’d9  Inferior: below, or toward the feet  Proximal: closer to, or toward the torso  Distal: away from the torso  Cephalad: toward the head  Caudal: toward the feet, or “tail”  Superficial: toward the surface (skin) of the body Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  10. 10. Kinesiology Terminology – cont’d10  Deep: toward the inside (core) of the body  Origin: the proximal attachment of a muscle or ligament  Insertion: the distal attachment of a muscle or ligament  Prone: describes the position of an individual lying face down  Supine: describes the position of an individual lying face up Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  11. 11. Osteokinematics 11  Planes of motion  Sagittal plane: left-right division  Frontal plane: front-back division  Horizontal (transverse) plane: top-bottom division  Anatomic position  Degrees of freedom  Number of planes of motion joint allows Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  12. 12. Osteokinematics – cont’d 12  Axes of rotation  Anterior-posterior  e.g., hip abduction/adduction  Medial-lateral  e.g., elbow flexion/extension  Vertical (longitudinal)  Rotational movements, e.g., trunk rotation Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  13. 13. Osteokinematics: Body Motions 13  Flexion  Motion of one bone approaching the flexor surface of another  Extension  An approximation of the extensor surfaces of two bones  Abduction  Frontal plane movement away from the midline  Adduction  Frontal plane movement to ward the midline Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  14. 14. Osteokinematics: Body Motions – cont’d14  Rotation  Bony segment spinning about its longitudinal axis of rotation  Inte rnalro tatio n  Anterior bone surface rotates toward the midline  Exte rnalro tatio n  Anterior bone surface rotates away from the midline   Circumduction  A circular motion through two planes Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  15. 15. Osteokinematics: Body Motions – cont’d15  Protraction  Translation of bone away from midline in a plane parallel to the ground  Retraction  Movement of a bony segment to ward the midline in a plane parallel to the ground Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  16. 16. Osteokinematics: Body Motions – cont’d16  Horizontal adduction and abduction  Shoulder motions in the transverse plane  Horizontal adductio n: hands come together  Horizontal abductio n: extremities move away from midline  Pronation  Forearm movement that turns the palm posteriorly  Supination  Forearm movement that turns the palm anteriorly Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  17. 17. Osteokinematics: Body Motions – cont’d17  Radial deviation  Lateral hand movement toward the radius  Ulnar deviation  Medial hand movement toward the ulna  Dorsiflexion  Sagittal plane ankle motion bringing the foot upward  Plantar flexion  Sagittal plane ankle motion pushing the foot downward Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  18. 18. Osteokinematics: Body Motions – cont’d18  Inversion and eversion  Frontal plane motions of the ankle/foot complex  Inve rsio n results in a medial-facing foot sole  Eve rsio n results in a lateral-facing foot sole Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
  19. 19. Osteokinematics: It’s All Relative19  Two perspectives of movement at a joint  Open-chain motion  Movement of distal segment of bone about a relatively fixed proximal segment  Closed-chain motion  Movement of proximal segment of bone about a relatively fixed distal segment Mosby items and derived items © 2009 by Mosby, Inc., an affiliate of Elsevier Inc.
