Prevalence of Students’ Misconceptions in Cardiovascular Physiology, and the Role of Taking Physiology Courses
Introduction: The cases of misconceptions are intellectual models of phenomena that are different from accepted scientific models of the same phenomena. The purpose of this study was to investigate the prevalence of cardiovascular misconceptions among students, and evaluate the role of cardiovascular physiology courses in eliminating them. Methods: This descriptive study was performed on 348 u...
متن کاملArtificial neural networks: applications in pain physiology
Artificial neural networks (ANNs) are intelligent systems that have successfully been used for prediction in different medical fields. In this study, the capability of ANN in predicting body behavior in pain-producing situations is evaluated. A three-layer back-propagation ANN is designed using MATLAB software. The inputs include the magnitude of stimulation in pain fibers, touch fibers and cen...

متن کاملPhysiology of parturition
Labor is a physiological event involving a sequential, integrated set of changes within the myometrium, deciduas, and uterine cervix that occur gradually over a period of days to weeks. Biochemical connective tissue changes in the uterine cervix appear to precede uterine contractions and cervical dilation, and all of these events usually occur before rupture of the fetal membranes. In other wor...
