Objective: The marginal, basal and subchorial regions of the placenta are considered to be more hypoxic than other regions. Therefore, it is not recommended to determine the increase in syncytiotrophoblast knots, based on the major morphological change in placental hypoxia, from the samples taken from these regions. However, the normal count of knots at various regions of placenta is not investigated.
