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