22、r Medical Student (7 year length of schooling) Year 05 To 06, First Semester, Soochow UniversityJan, 2005ANSWERPART Explanation of terminology:（20 Points）1Positive feedback: There are situations where the initial response produces further change in the same condition. This is self-perpetuating and i
23、s called positive feedback.2Antiporter: The carrier protein couples the movement of molecules in opposite directions, then it is called an antiporter and the molecules are said to be counter-transported.3Resting potential: Under the quiet or calm conditions (without any stimuli), the membrane displa
24、ys the potential difference between inside and outside the cell.4Mean Arterial Pressure: MAP= Diastolic Pressure + 1/3 Pulse Pressure, about 100mmHg (13.3kPa). 5Surfactant: The fluid lining the alveoli contains material, a phospholipid secreted by type pneumocytes which lowers the surface tension of
25、 alveoli and cause surface tension to change with volume.6Basic electrical rhythm (BER): The basic electrical rhythm (BER) is a slow spontaneous depolarized wave in the GI tract and BER of smooth muscle cells form the basis (action potential) of stomach contractions.7Respiratory quotient: RQ=Mol num

(8 Points)Three major components of an ECG are P wave, QRS complex,T wave

30、at are determinants and regulation of RBF? (8 Points)RBF is determined by systemic arterial blood pressure and renal vascular resistance.RBF demonstrates autoregulation.Autoregulation involves afferent not efferent arterioles.Autoregulation is explained either by the myogenic hypothesis or tubuloglo
31、merular feedback.3 How are pulmonary ventilation Influenced by PO2 ,PCO2 , and pH? (10 Points)Two groups of chemoreceptors, medullary and peripheral, send afferent information to the medulla and influence the depth and rate of respiration.Medullary chemoreceptors are sensitive to pH and increase ven
32、tilation when pH falls.Peripheral chemoreceptors are sensitive to pH, PO2 , and PCO2, with PCO2 being most effective.Sensitivity of the peripheral chemoreceptors is influenced by pH,. PO2 , and PCO2.4 What are typical and common patterns of motility in different parts of gastrointestinal tracts? (8
33、Points)The common patterns of motility in different parts of gastrointestinal tracts is peristalsis.The typical patterns of motility at stomach is receptive relaxation for store of food.The typical patterns of motility at small intestine is segmentation for turning food into smaller particles and he
34、lping absorption.The typical patterns of motility at large intestine is mass movement for pushing the contents in the colon into the next downstream segment.5 What are functions of thyroid hormones ? (8 Points)(1)Because T3 acts by inducing DNA transcription, its effects on tissue are the result of
35、protein synthesis, primarily the synthesis of enzymes.(2)Thyroid hormones are required for normal growth throughout life.(3)Thyroid hormones affect basal metabolic rate, metabolism, the cardiovascular system, and the nervous system.(4)Symptoms of thyroid hormone excess or deficiency can be predicted
36、 from their normal effect.6 How does the human bodys reflex response to cold? (8 Points)When a fall in core body temperature is detected by the hypothalamus, the reflex compensation involves reducing heat loss and generating more heat by increasing metabolic rate and through shivering.(1)Objective o
37、f body is to reduce heat loss and increase heat production.(2)Reducing heat loss occurs by decreasing skin blood flow and through behavioral responses.(3)Increasing heat production occurs through metabolic effects of thyroxin and catecholamines as well as by shivering.(4)Sustained exposure to extreme cold depresses hypothalamic temperature control mechanism and produces dilation of skin vasculature.- 9 -
