Principles of Functional Exercise

(Ben Green) #1

  • Cartilaginous joints: cartilage between joint surfaces

  • Synchondroses: coastal cartilage, growth plates

  • Symphyses: secondary cartilaginous joints; intervertebral disk, pubic symphysis

  • Fibrous joints: union of bones by fibrous connective tissue

  • Sutures: joints between cranial bones

  • Gomphoses: between teeth and jaw

  • Syndesmosis: interosseous joints such as sacroiliac joints


Diarthroses: (synovial joints, moveable joints)



  • Plane synovial: uniaxial; translatory motion. Z joints, carpal joints

  • Ginglymus: uniaxial; hinge motion. Elbow joint

  • Trochoid (pivot): uniaxial; rotation of one bone around a single axis. Proximal radioulnar
    joint (elbow)

  • Bicondylar (condyloid): mostly uniaxial, some rotation; two convex condyles articulating
    with two concave condyles. Knee joint.

  • Ellipsoid: biaxial: two orthogonal axis (flexion/extension in one axis,abduction/adduction
    in another). Radius, scaphoid and lunate at wrist.

  • Seller (saddle): multiaxial; two saddle-shaped surfaces articulation with each other.
    Sternoclavicular joint.

  • Spheroidal (ball and socket): multiaxial; three degrees of motion. Glenohumeral
    (shoulder) and femeroacetabular joint (hip)


Tendon:



  • Connects skeletal muscle to bone

  • Type of dense connective tissue: contain collagen fibers in parallel bundles

  • Great tensile strength to sustain great forces exerted by muscle belly


Ligament:



  • Connects bone to bone

  • Dense connective tissue

  • More elastic fibers than tendons-must stretch more

  • Three types: reinforcing (joint capsules); guiding (in movements); restrictive (limit movement)


Neck:
Flexion: 70-90 degrees
Touch sternum with chin.
Extension: 55 degrees
Try to point up with chin.
Lateral bending: 35 degrees
Bring ear close to shoulder.
Rotation: 70 degrees left & right
Turn head to the left, then right.
Lumbar Spine:
