  1. The act of listening to sounds of the body
    auscultation
  2. Bones of the skeleton that form the central or supportive core
    axial skeleton
  3. specialized proteins found within the muscle cells that interact with one another to cause muscle force production
    • contractile proteins
    • (major ones are actin and myosin)
  4. the articulations between bones, typically classified according to structure as being fibrous, cartilaginous, or synovial
    joints
  5. a single somatic motor neuron an the group of muscle fibers innervated by it
    motor unit
  6. the orientation of the muscle fibers to the longitudinal axis of the muscle
    muscle fiber architecture
  7. specialized proteins found within muscle cells that block the binding of the contractile proteins to one another and thus keep the muscle in a relaxed state
    • regulatory proteins
    • (troponin and tropomyosin)
  8. front of the body
    anterior
  9. below the surface and not relarively close to the surface
    deep
  10. furthest point in distance from a given anatomic reference point
    distal

    inferior
  12. away from the midline of the body
    lateral
  13. toward the midline of the body
    medial

  16. located close to or on the body surface
    superficial
  17. toward the head
    superior
  18. What is the primary function of the cardiovascular system
    transport of nutrients and removal of waste products
  19. what nutrients does the cardiovascular system distribute
    nutrients such as glucose, free fatty acids, amino acids to cells
  20. what metabolic waste does the cardiovascular system remove
    carbon dioxide, urea, lactate
  21. the heart is covered by a double-walled, loose fitting, membranous sac called
    pericardium
  22. the thickest layer of tissue in the heart
    myocardium
  23. inner layer of the myocarduym is lined with a thin layer of
    endocardium
  24. the atria and ventricles of the heart are separated by the
    interartial septum and interventricular septum
  25. blood through the heart
    • 1. superior/inferior vena cava
    • 2. right atrium through tricuspid valve
    • 3. right ventricle through pulmonary valve
    • 4. pulmonary artery to lungs
    • 5. pulmonary veins to left atrium
    • 6. biscupid valve to left ventricle
    • 7. aortic valve to aorta to body
  26. components of the heart's conduction system
    SA node, AV node, AV bundle, bundle branches, purkinje fibers
