  • Chapter 3 Anatomy and Kinesiology
  • Anatomical Position
  • Sagittal Frontal Horizontal
  • General Joint Action Terms
    • Flexion—characterized by the joint angle diminishing (most flexion movements are forwards, except for the knee joint)
    • Extension—return from flexion; joint angle increases
    • Abduction—movement away from the midline of the body
    • Adduction—movement toward the midline of the body
    • Rotation—movement around an axis
    • Circumduction—movement in a 360 ° circle

  • Connective Tissues
    • Ligament —a non-elastic band of fibrous tissue that connects bone to bone and provides joint stability
    • Tendon —dense, fibrous tissue that forms the end of a muscle and attaches muscle to bone
    • Fascia —fibrous tissue that forms sheaths for individual muscles, fasciculi, and muscle fibers
    • Cartilage —white, semi-opaque tissue that cushions joints and prevents wear on joint surfaces
  • Roles Muscles Play
    • Agonist or Prime Mover —the muscle directly responsible for the movement that you see
    • Antagonist —the muscle that works in opposition to the prime mover
    • Assistor —the muscle that assists in performing a movement
    • Stabilizer —a muscle that maintains a static or isometric contraction and prevents unwanted movement
  • Muscle Actions
    • Isometric—a held, static muscle action in which there is no change in the joint angle or muscle length.
    • Isotonic/Dynamic—joint movement occurs
    • Two Types:
    • * Concentric—shortening action
    • * Eccentric—lengthening action
