What structure is associated with Wharton's jelly?

Wharton's jelly is a gelatinous substance found within the umbilical cord, which serves several important functions. This jelly-like tissue is primarily composed of a rich network of mucopolysaccharides, which help provide cushioning and support to the blood vessels running through the umbilical cord, namely the two arteries and one vein. This protective function is crucial for maintaining the integrity of these vessels and ensuring that they can efficiently transport nutrients and oxygen between the mother and developing fetus.

The presence of Wharton's jelly is significant during pregnancy as it helps prevent compression of the umbilical vessels, which could lead to complications such as fetal distress. Thus, the association of Wharton's jelly with the umbilical cord is fundamental to its role in fetal development and highlights its importance in obstetrics.
