What is the normal length and diameter range of the umbilical cord?

The normal length and diameter range of the umbilical cord is important for assessment and clinical practice in neonatology. The correct range for the umbilical cord length is typically 30-100 cm, which encompasses the average length of the cord observed in healthy newborns. This range is crucial because a cord that is too short may lead to complications such as restricted fetal movement or issues during delivery, while a cord that is excessively long might be at risk for complications like cord accidents.

Additionally, the diameter of 1.5-2 cm falls within the normal variability for the umbilical cord. This thickness ensures that the cord has adequate capacity for blood flow, facilitating proper nutrient and oxygen delivery to the fetus through the placenta.

In summary, the length and diameter range provided in this choice are consistent with clinical findings regarding umbilical cord characteristics in healthy neonates, emphasizing the significance of both metrics in prenatal assessments.
