  1. 1It is important that the contraction of all the muscle cells of the heart wall is coordinated and synchronised so that the pumping action of the heart is both effective and efficient.
    1. ARichtig
    2. BFalsch
  2. 2The 'conducting (conduction) system' is made up of...
    1. Acardiac veins and coronary arteries
    2. Bsmall groups of specialised neuromuscular cells
  3. 3What normally initiates the heartbeat?
    1. AInternodal Pathways
    2. BSA (Sino-Atrial) Node
    3. CAV (Atrioventricular) Node
    4. DBundle of His
  4. 4Within which wall is the SA Node situated?
    1. Aleft atrium
    2. Bright atrium
    3. Cleft ventricle
    4. Dright ventricle
  5. 5There is a brief pause in the conduction of the impulse at the AV Node so that atrial contraction (and thus ventricular filling) is completed before ventricular contraction begins.
    1. ARichtig
    2. BFalsch
  6. 6The Bundle of His divides into how many branches?
    1. A1
    2. B2
    3. C3
    4. D4
  7. 7The order in which the heartbeat impulse moves is...
    1. ABundle of His, AV Node, SA Node, Bundle Branches, Purkinje Fibres
    2. BSA Node, Bundle of His, Purkinje Fibres, AV Node, Bundle Branches
    3. CSA Node, AV Node, Bundle of His, Bundle Branches, Purkinje Fibres
  8. 8Which areas of the heart contract first?
    1. AVentricles
    2. BAtria
  9. 9Even though the SA Node normally initiates the heartbeat, the cells of the conducting system and of the heart muscle itself are also able to spontaneously depolarise and initiate a heartbeat.
    1. ARichtig
    2. BFalsch
  10. 10Which part of the conducting system is known as the 'pacemaker'?
    1. ABundle of His
    2. BSA Node
    3. CAV Node
    4. DPurkinje Fibres
