  1. Non synovial joints
    The bones are United by fibrous tissue or cartilage and are immovable like the sutures in the skull or only slightly movable like the vertebrae
  2. Synovial joints
    Freely movable because they have bones that are separated from one another and enclosed in a joint cavity, this cavity is filled with lubricant called synovial fluid
  3. Cartilage
    Avascular, receives nourishment from synovial fluid, stable connected tissue with slow cell turnover, tough & firm yet flexible consistency, cushions the bones and gives a smooth surface to facilitate movement
  4. Ligaments
    Fibrous bands running directly from one bone to another bone that strengthen the joint and help prevent movement in an undesirable direction
  5. Bursa
    Enclosed sac filled with viscous synovial fluid Located in areas of potential friction
  6. Fasciculi
    Bundles of muscle fibers that compose skeletal muscle
  7. Skeletal muscle movement
    Flexion, Extension, abduction, adduction, pro nation, supination, circumduction, inversion, eversion, rotation, protraction, retraction, elevation, depression
  8. Flexion
    Bending a limb at a joint
  9. Extension
    Straightening a limb at a joint
  10. Abduction
    Moving a limb away from the midline of the body
  11. Adduction
    Moving a limb toward the midline of the body
  12. Pronation
    Turning the forearm so the Palm is down
  13. Supination
    Turning the forearm so the Palm is up
  14. Circumduction
    Moving the arm in a circle around the shoulder
  15. Inversion
    Moving the sole of the foot inward at the ankle
  16. Eversion
    Moving the sole of the foot outward at the ankle
  17. Rotation
    Moving the head around a central access
  18. Protraction
    Moving a body part forward and parallel to the ground
  19. Retraction
    Moving a body part backward and parallel to the ground
  20. Elevation
    Raising a body part
  21. Depression
    Lowering a body part
  22. Temporomandibular joint
    The articulation of the mandible and the temporal bone, can be felt in the depression anterior to the tragus of the ear, allows 3 motions: hinge action to open and close the jaw, gliding action for producing and retraction, gliding for side to side movement of the lower jaw
  23. Vertebrae
    33 connecting bones stacked in a vertical column. 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, 3 or 4 coccygeal
  24. Intervertebral disks
    Elastic fibrocartilaginous plates that constitute 1/4 of the length of the column
  25. Nucleus pulposus
    Soft, semi fluid, mucoid material (consistency of toothpaste) that is the center of each Intervertebral disk
  26. Glenohumeral joint
    Ball and socket joint that is the articulation of the humerus with the glenoid fossa of the scapula
  27. Palpable landmarks of the elbow
    Medial and lateral epicondyles of the humerus And the large Olecranon process of the ulna
  28. Radiocarpal joint
    (The wrist) The articulation of the radius on the thumb side and a row of carpal bones
  29. Midcarpal joint
    Articulations between the 2 parallel rows of carpal bones
  30. Metacarpophalangeal, Interphalangeal
    Joints that permit finger flexion and extension
  31. Palpation of the hip
    You can fill the entire iliac crest from the anterior superior iliac spine to the posterior
  32. Ischial tuberosity
    Lies under the gluteus Maximus muscle and is palpable when the hip is flexed
  33. Greater trochanter
    Normally the width of the person's Palm below the iliac crest 1/2 way between the anterior superior iliac spine and the ichial tuberosity. feel it when the person is standing, in a flat depression on the upper lateral side of the thigh
  34. Knee joint
    Hinge joint that is the Articulation of the femur, the tibia and the patella. (Largest joint in the body)
  35. Suprapatellar pouch
    The knees synovial membrane At the superior border of the patella (largest in the body)
