Chorion and chorionic villi

STRUCTURE & FUNCTION

Understand what you see.

Forms the fetal placental interface and supports exchange through villous architecture.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Outer fetal membrane
  2. Villi project toward maternal tissues
  3. Villi contain fetal vascular cores at mature stages
02 / KEY STRUCTURES

Point them out.

Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.

  • Mesodermal core
03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

01How do you identify chorion and chorionic villi?
SUGGESTED ANSWER

Outer fetal membrane. Villi project toward maternal tissues. Villi contain fetal vascular cores at mature stages.

02Name the stages of chorionic villi.
SUGGESTED ANSWER

Primary villi have trophoblast cores; secondary villi acquire extraembryonic mesoderm; tertiary villi contain fetal vessels.

03Which chorionic region contributes most to placenta?
SUGGESTED ANSWER

Chorion frondosum at the embryonic pole; villi regress over the smoother chorion laeve.

04Which structures should you point out on this reference?
SUGGESTED ANSWER

Trophoblast covering; Mesodermal core; Fetal capillaries. Forms the fetal placental interface and supports exchange through villous architecture.
