Across
  1. 1. refers to relaxation phase
  2. 4. this endocrine gland releases 2 hormones: a releasing and inhibiting hormone.
  3. 5. these excitatory receptors lie on the motor-end plate.
  4. 7. epinephrine and norepinephrine are examples
  5. 8. this is the first binding site for a lipid-based hormone
  6. 12. epinephrine and norepinephrine use this type of synergy
  7. 14. recording the electrical activity produced by the heart.
  8. 18. if blood is incompatible, antibodies will cause.
  9. 20. hydrophilic hormones undergo this type of action
  10. 21. this heart sound occurs at the beginning of the T-wave
  11. 22. this junction lies on the motor-end plate.
  12. 23. the functional unit of skeletal muscle
  13. 26. what binds to myosin head to allow detachment of actin?
  14. 28. blood typing system
  15. 30. protein-based hormones are "hydro-"
  16. 31. straw colored liquid consisting of water and dissolved solutes
  17. 32. refers to the contraction phase
  18. 35. the endocrine system utilizes these chemical messengers
  19. 36. which neurohormone can act via two second-messenger systems?
  20. 39. substance which induces an immune response in the body.
  21. 40. a single rapid contraction and relaxation
  22. 41. this falls off myosin head to cause "power stroke" to occur.
Down
  1. 2. the heart has refractory periods to prevent?
  2. 3. what range determines whether or not a cell will respond to a hormone?
  3. 6. what effect is used to increase receptors on the target cell?
  4. 9. amount of blood ejected from ventricles during systole
  5. 10. this action occurs with lipid-based hormones
  6. 11. are lipid-derived and Lipophilic
  7. 13. when hormones are released in high concentration, desensitization or ______ occurs?
  8. 15. this node functions as the pacemaker of the heart.
  9. 16. this heart sound comes after the QRS complex
  10. 17. this system is composed of the cardiovascular and lymphatic systems.
  11. 19. what effect: hormone #1 allows for hormone #2 to have a better response
  12. 24. oxytocin and prolactin use this type of synergy
  13. 25. where gas exchange occurs, type of blood vessel
  14. 27. calcium binds and pulls this structure to aid in cross-bridge formation.
  15. 29. this factor can cause Erythroblastosis fetalis.
  16. 32. specialized reticulum of skeletal muscle
  17. 33. amount of blood left in ventricles at end of systole
  18. 34. this is the second binding site for a lipid-based hormone
  19. 36. volume of blood in ventricles at end of diastole.
  20. 37. specific sodium channel that contributes to the autorhythmic aspect of the heart
  21. 38. this gland is considered the "master gland"
  22. 40. stimulus at the end of relaxation period, slow build up of tension.
