生理学考试重点（Physiological examination emphasis） Stimulus threshold: the minimal stimulus intensity that can cause tissue cells to react. Action potential: when a cell is stimulated by an effective stimulus, the membrane potential changes rapidly and reversibly on the resting potential and can be transmitted over a long distance. Threshold potential: the critical value of the membrane potential that triggers an action potential is called threshold potential. Stroke volume: the amount of blood contracted per ventricle at each contraction. Cardiac output: the volume of blood produced by a single ventricle per minute. Time: refers to the maximum inspiratory capacity, with the fastest speed to the maximum and then calculates gas exhaled gas, the first seconds, second seconds, three seconds at the end of the breath and percentage of the forced vital capacity. Alveolar ventilation volume: the actual volume of alveolar regeneration per minute. Digestion: the process in which food is broken down into absorbable small molecules in the digestive tract. Heat produced by the consumption of one liter of oxygen when a nutrient is oxidized. Body temperature: the mean temperature of the deep tissue of a body, that is the body nucleus temperature. Glomerular filtration: when blood flows through the glomerulus, water and small molecules in the plasma filter through the filter membrane into the renal sac, forming the process of urine. Effective filtration pressure is the driving force of glomerular filtration. Under the condition of filtration membrane permeability and renal plasma flow constant, the amount of urine production depends mainly on the effective filtration pressure. Visual acuity: the ability of the eye to distinguish the fine structure of an object, that is, the ability to distinguish the minimum distance between two points on an object. Referred pain: a pain or hyperalgesia caused by an internal disorder in a specific part of the body surface. Stretch reflex: when the skelet
