Definitions of FUNICULUS UMBILICALIS
Sort: Oldest first
By Stedman, Thomas Lathrop
A cord-like substance, which extends from the placenta to the umbilicus of the foetus. It is composed of the chorion, amnion, an albuminous secretion called the Jelly of the Cord, cellular substance, an umbilical vein, and two umbilical arteries. The former conveys the blood from the placenta to the foetus- the latter return it. All these parts are surrounded by a sheath- Investitura seu Vagina funiculi umbilicalis. Its usual length is from 16 to 22 inches.
