  2. Synarthrosis
    • Motion: None
    • Structure: Fibrous-Suture
    • Example: Skull
  3. Syndesmosis
    • Motion: Slight
    • Structure: Fibrous-Ligamentous
    • Example: distal tibiofibular
  4. Gomphosis
    • Motion: none
    • Structure: Peg in Socket
    • Example: Tooth
  5. Amphiarthrosis
    • Motion: Little
    • Structure: Cartilagenous
    • Example: intevertebral discs
  6. Diarthrosis
    • Motion: Free
    • Structure: Synovial

  7. What dictates the motion allowed at a bone joint?
    The shape of the bone
  8. What are the 2 kinds of tension within a muscle?
    • Active
    • Passive
    • ** the total amount of tension within a muscle is a combination of active and passive **
  9. What is active tension?
    • The amount of tension that a muscle can actively generate
    • controlled by: Actin, myosin & the sliding filament theory
  10. What is passive tension?
    • the tension in the non-contractile units of the muscle
    • Increases as it is stretched
    • Decreases when it is contracted
  11. What is muscle excursion?
    • The total distance a muscle can lengthen from its maximally shortened position
    • Can shorten to 1/2 its resting length
    • Can lengthen to 1 1/2 its resting length
    • Has the most power at 1.2X it's resting length
  12. Tenodesis
    • Passive tendon tension builds up to the point that it pulls everything in
    • Functional with quadriplegic's to pull in their fingers
  13. Observation of a patient begins when?
    At first contact
  14. Cyanosis
    skin turns blue due to a lack of O2 or too much CO2
  15. Pallor
    too little bloodflow or hemoglobin
  16. Erythema
    Localized redness of the skin due to; sunburn, fever or carbon monoxide poisoning
  17. What causes yellow skin?
    increased carotin levels or liver disease
  18. What is a pitting edema?
    When you palpate the skin stays indented
  19. Anthropometric Measurements
    The study of measurements of the human body
  20. Circumferential measurements
