Introduction Placenta is a functional unit between the mother and the foetus. Only eutherian mammals possess placenta. Human placenta is discoid, deciduate, haemochorial, chorioallantoic, labyrinthine and endocrine gland which connects developing embryo by umbilical cord to the endometrium of mother’s uterus. It develops from two sources. The fetal component which is the principal component develops from chorion frondosum and the maternal component from decidua basalis. The fetal surface is smooth, covered by amnion and presents the attachment of the umbilical cord close to its centre. The maternal surface is rough, irregular and spongy and is mapped out into 15-20 convex polygonal areas known as lobes or cotyledons which are limited by fissures. Material and Method: This is a prospective study conducted in the Department of Anatomy at Index Medical College over a period of 1 year. Inclusion Criteria: Totally, 217 healthy mothers who gave birth to uncomplicated singleton pregnancy, and their new-borns were included in the study. Exclusion Criteria: Subjects with diabetes mellitus, hypertension, anaemia, vascular diseases and multiple pregnancies were excluded in this study. Initially the vernier calipers were checked for zero error with jaws closed. The jaws of the calipers were placed on either side of the peripheral margin of the placenta with firm pressure on the placental surface. When both the locking screws of the calipers were tightened the calipers were removed from the placenta and the readings were recorded after the measurement in the main scale of the calipers were read to the nearest tenth of the centimeter.
