人体生理学实验课应以定性的快速直观的结果去验证课堂理论。 我们在做消化道平滑肌生理特性观察实验时,是在特定的环境中,将离体的一段小肠,一端固定在通气钩上,另一端游离,以连线与描记装置垂直相连,并放进一浴槽内,加入预先按比例配制的细胞外液——台氏液,恒温37℃,持续少量给氧的条件下,使小肠平滑肌维持在生理活性状态,当加入某药品后,立即引起这种生理活性的增强或者减弱,以观察消化道平滑肌的自动节律性收缩的频率,振幅及紧张度,要求学生在实验中直接进行观察记录。 Human physiology experimental class should be qualitative and rapid and intuitive results to validate the classroom theory. We do experiments in the observation of the physiological characteristics of the digestive tract smooth muscle in a specific environment, an isolated small intestine, one end fixed to the ventilation hook, the other end of the free, connected with the vertical line and tracings, and into a Bath, adding pre-proportioned extracellular fluid - Tyrode’s solution, constant temperature 37 ℃, continued a small amount of oxygen under the conditions of the small intestine to maintain the physiological activity of the smooth muscle state, when the addition of a drug, immediately caused by this physiological Activity increase or decrease in order to observe the automatic rhythmic contraction of gastrointestinal smooth muscle frequency, amplitude and tension, require students to directly observe and record in the experiment.
