Vascular & Muscle System

gina_evans0312 Haematology and Anatomy English 66 cards

Cards in this deck (66)

  1. 1Cardiovascular SystemHeart & blood vessels
  2. 2Lymphatic SystemOverflow system- lymphatic plexus, vessels, lymph nodes & lymphoid organisms
  3. 3Distributing ArteryProbably this if it has a name- tunica media is mostly smooth muscle
  4. 4Vascular smooth muscle fibres...Are under autonomic control
  5. 5Sympathetic ActivityCauses vasoconstriction/vasodilation
  6. 6Vasa vesorumBlood vessels for artery walls
  7. 7Conducting ArteryTunica media contains more elastic tissue than smooth muscle
  8. 8End ArteryDon't end in capilliaries but end in arteries
  9. 9AnostamosisA cross connection between two arteries-regulate blood flow between them
  10. 10Arterioles/Meta-ArteriolesThick muscle & small lumen
  11. 11Precapillaric sphinctersControl blood flow to the capillaries
  12. 12Veins contain .... to help maintain pressureValves, diastole, muscles squeeze veins
  13. 13Single Squamous EpitheliumFound in lungs and muscles
  14. 14Fenestrated CapillariesAllow hormone transfer
  15. 15Fenestrated Capilliaries are found in...Found in kidneys/endocrine glands
  16. 16SinusoidsLarger holes to allow passage of larger molecules
  17. 17Sinusoids are found in...Bone marrow and spleen
  18. 18Major ActorPrime mover that initiates joint movement
  19. 19SynergistAssists prime mover
  20. 20FixatorsStabilizes the prime mover
  21. 21AntagonistReverses the action of prime mover
  22. 22Motor UnitSingle motor unit and all the muscle fibers it stimulates
  23. 23Damage to nerveCauses muscle paralysis
  24. 24Motor Unit RecruitmentMore contraction requires more motor units
  25. 25Powerful movements requireMore, larger motor units- strength required, not precision
  26. 26Precise MovementSmaller motor units- less power but more muscle control
  27. 27Satellite cellsThe regenerative cells of the muscle
  28. 28Damage to connective tissue leads to...Storage
  29. 29What causes scarring?Collagen is put down an irregular manner
  30. 30Damage to the epidermis causes...No damage
  31. 31Damage to the dermis causes...Scarring
  32. 32Muscle regenerationLimited due to small amount of satellite cells
  33. 33When damaged, muscle cells increase in...Size, not number
  34. 34HypertrophyIncrease in muscle cell size
  35. 35Skin hyperplasmIncrease in skin cell number
  36. 36Nerva Pathology caused by...Stroke/viral damage
  37. 37Bells Palsy usually effectsFacial nerve (one of two)
  38. 38Symptoms of Bells PalsySmooth forehead, drooping eyebrow and side of mouth
  39. 39Disease AtrophyLoss of muscle size due to disuse i.e. through a fracture
  40. 40Myastheria GravisAutoimmune disorder attacking Ach receptors
  41. 41Neuromuscular Junction PathologyEffects precise rather than gross movement
  42. 42Muscular Pathology i.e.Duchenne Muscular Dystrophy
  43. 43Dystrophin gene mutation found onX allele (recessive)
  44. 44Dystrophin effects...Larger muscles first
  45. 45Test for Duchenne Muscular DystrophyA child will use their hands for support as they stand
  46. 46Cardiac Muscle TraitsIntercalated Disks, Shorter fibres, more mitochondria & lower Ca2+ reserves
  47. 47SyncytiumA single cell/cytoplasmic mass formed by nuclei splitting or cell fusion
  48. 48Cardiac muscle has greater capacity for...Continuous contraction
  49. 49Autorythmic fibresMuscle fibres capable of contracting without stimulation
  50. 50Smooth muscleSpindle shaped involuntary muscle
  51. 51Smooth muscle movementsAre slow but sustained
  52. 52Irregular muscle filaments are attached to ... in smooth muscleDense bodies
  53. 53Smooth muscle is triggered by...Autonomic signalling, chemicals or mechanical events
  54. 54Abdomial AortaFound in abdomen, feeds liver, stomach and spleen
  55. 55Common Iliac ArteryProvides blood to the leg
  56. 56Why is the aorta close to the spine?Protection
  57. 57Brachiocephalic AortaFirst branch of the aortic arch
  58. 58Subclaven arteryProvides blood to the arm
  59. 59Common carotid arteryProvides blood (one on each side) to the brain up the neck
  60. 60Coeliac arteryProvides spleen, liver and stomach branches
  61. 61Superior mesentric arteryProvides small intestine
  62. 62Name the aorta's three partsAscending Aorta, Aortic Arch & Descending Thoracic Aorta
  63. 63Where most blood is foundVein
  64. 64Internal/External LamiaAllows artery to stretch and avoid rupture due to pressure
  65. 65Lacking in veins and capillaries, found only in arteriesElastic Lamina
  66. 66Brachiocephalic artery branches into...Subclaven and common carotid arteries
