Background: Apara (Placenta) is a vital organ of higher mammals which is attached to the Garbhashaya (uterus)and is connected to the fetus through the Nabhinadi (umbilical cord). The examination of Apara( placenta) and it's attachment to umblical code soon  after its expulsion in the third stage of labour, gives a clear idea of what had happened with it in the intrauterine period of its existence. Apara, by virtue of its appearance and functions described in Ayurveda can be well correlated as placenta; and Rasavahininadi or Nabhinadi to the umbilical cord.
Objective: To evaluate the variation in placental attachment of umbilical cord and its relation to fetal birth weight. As congenital anomalies are often associated with umbilical cord insertion anomalies, early identification of the same can pick congenital anomalies.
Materials and Methods: For the conceptual study, Ayurvedic classical and modern texts, books on the contemporary science, journals, presented papers and internet were reviewed. For clinical evaluation 39 specimens were collected after proper from the Department of Obstetrics and Gynaecology, Alva’s Health Centre, Moodbidri, for the assessment of placental attachment with umbilical cord and its diameter, thickness, perimeter, weight along with length of umbilical cord.
Discussion and Conclusion: Common attachment of umbilical cord to placenta is central. It varies at many times of attachment. Both Apara and Nabhinadi along with placenta are interrelated with each other in determining the fetal growth. There exists a positive relationship on attachment of Nabhinadi to Apara and fetal birth weight.
