chorionic stem villus

placental stem villus

A chorionic villus that provides structural support to the villous tree. A chorionic stem villus is characterized by a condensed fibrous stroma in which fetal arteries, veins, arterioles, and venules are embedded. It represents a distributing framework for fetal chorionic circulation, supplying the floating villi. It can exhibit a diameter ranging from approximately 3000 μm (trunci near the chorionic plate) to 80 μm (smallest ramuli chorii).

常见问题

What is the chorionic stem villus?
A chorionic stem villus is the primary branching structure of the placental villi that arises directly from the chorionic plate and serves as the main trunk for further villous branching.
Where is the chorionic stem villus located?
Stem villi originate from the chorionic plate and extend into the intervillous space, forming the primary structural framework of the villous tree.
What is the function of the chorionic stem villus?
Stem villi provide the structural basis for the branching placental villi and contain the main fetal blood vessels that distribute blood throughout the villous system.
What is the chorionic stem villus connected to?
Stem villi connect the chorionic plate to secondary and tertiary branches, and contain fetal blood vessels that transport blood between the fetus and placenta.
Why is the chorionic stem villus clinically important?
Pathological changes in stem villi such as fibrosis or hypoplasia are associated with adverse pregnancy outcomes and can be detected through placental histopathology.
