HRM in Indigenous and MNCs in the current recession. Ireland has one of the most globalised economies in the world. One of its main attributes is the prioritising the attraction and retention of FDI through a combination of incentives‚ particularly low corporation tax and liberalised trade policies. The success of this policy is manifest in the large numbers of MNCs located there and its status as one of the world’s most FDI-intensive economies (Barry‚ 2007; Rios-Morales and Brennan‚ 2009).

of an action potential? P wave: atrial depolarization; QRS complex which represents the onset of ventricular depolarization; T wave: ventricular replarization 22. What is the diagnostic significance of the ECG? Useful in diagnosing abnormal cardiac rhythms and conduction patterns and in following the course of recovery from a heart attack 23. How does each ECG wage relate to contraction and relaxation of the atria and ventricles? First wave: represents atrial depolarization which causes

rapid and irregular atrial contractions that result in ineffective emptying of the atria. The two upper chambers (atria) beat out of sync with the two lower chambers (ventricles). This ineffective rhythm and ineffective emptying causes decreased cardiac output and stasis of blood. The stasis that results can cause harmful clots to pool in the atria putting patients at risk for thromboembolic stroke‚ pulmonary embolus‚ or renal embolus. An estimated 15% to 25% of strokes are associated with AF (Hardin

Sample Physiology MCQs 1. Compound action potentials can be graded responses. True 2. The sciatic nerve contains axons of both afferent and efferent neurones. True 3. The absolute refractory period of an action potential is the period after an initial stimulus when it is impossible to evoke another action potential with a second stimulus. True 4. The refractory periods of individual axons are important as they dictate the maximal action potential firing rate of a neuron. True 5. Compound action

Allows completion of atrial contraction before initiation of ventricular systole. 2. Even though cardiac muscle has an inherent ability to beat‚ the nodal system plays a critical role in heart physiology. What is that role? Ensures that depolarization proceeds in an orderly manner from atria to ventricles; accelerates and coordinates heart activity to
