Contents COVER -- HALF-TITLE -- TITLE -- COPYRIGHT -- CONTENTS -- LIST OF ABBREVIATIONS -- DEDICATION -- PREFACE -- A CHANGE IN POSTURE -- 1. What happens to the stroke volume when standing up after a period of lying supine? Explain why this change occurs -- 2. What happens to the arterial pressure during this period? -- 3. What is the physiologic relationship between the cardiac output (CO) and the arterial pressure normally? -- 4. What physiologic mechanisms ensure that the arterial pressure is maintained after standing? -- 5. Give some common causes for postural hypotension. -- ACID-BASE
1. Define the pH. -- 2. What is the pH of the blood? -- 3. Where does the H+ in the body come from? -- 4. What are the main buffer systems in the intravascular, interstitial and intracellular compartments? -- 5. What does the Henderson-Hasselbalch equation describe, and how is it derived? -- 6. Which organ systems are involved in regulating acid-base balance? -- 7. How does the kidney absorb bicarbonate? -- 8. Define the base deficit. -- ACTION POTENTIALS -- 1. What is meant by the 'equilibrium potential' for an ion? -- 2. What is meant by the 'resting membrane potential' for a cell?
3. What is the typical value of the resting membrane potential for a neurone? -- 4. What is the importance of the Na+ /K+ pump for the equilibrium potential? -- 5. What is an action potential? Draw and label the axes of a typical action potential for a neurone. -- 6. Briefly describe the ionic basis for the action potential. -- 7. What is meant by the 'refractory period'? -- 8. What is the effect of myelination on a nerve fibre? -- 9. What types of nerve fibres are there? -- 10. Briefly list some drugs that may alter the conduction along a neurone. -- ADRENAL CORTEX I
1. What are the anatomic layers of the adrenal cortex, and which hormones do they produce? -- 2. What is the basic composition of these hormones? -- 3. From which molecule are these hormones all derived? -- 4. What are the main mineralocorticoids, glucocorticoids, androgens and oestrogens produced? -- 5. What are the physiological effects of aldosterone? -- 6. Describe the principle mechanisms controlling aldosterone release -- 7. Where is renin produced? -- 8. Summarise the main effects of glucocorticoids. -- 9. What are the principle metabolic effects?
10. What is the basic mechanism of action of the adrenal cortical hormones? -- ADRENAL CORTEX II - CLINICAL DISORDERS -- 1. What types of hyperaldosteronism are there, and what basic features characterise each? -- 2. What causes Conn's syndrome? -- 3. What is the dominant clinical feature? -- 4. What biochemical abnormalities might you detect? -- 5. What will the urine show? -- 6. Apart from the important features mentioned above, what other clinical feature commonly occurs with Conn's syndrome? -- 7. Which aldosterone antagonist has been used in the medical management of this disorder?
8. What are the most common causes of Cushing's syndrome of cortisol excess?
Summary An understanding of basic sciences is the cornerstone of medical and surgical training, and viva examinations in particular remain a source of anxiety for many candidates. Applied Surgery Physiology Vivas follows the same format as the hugely popular General Pathology Vivas and Surgical Critical Care Vivas. It gives candidates a means of practising some of the most common questions that they will be asked in their viva examinations, with detailed model answers and diagrams to highlight key points where necessary. Pocket-sized for portability, and packed with useful information in an easy-to-us
