Cleavage & blastocyst
Understand what you see.
Establishes the early conceptus before implantation.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Cleavage divides the conceptus into smaller blastomeres
- Morula is a compact cell cluster
- Blastocyst has a cavity, inner cell mass and outer trophoblast
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.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
01How would you identify cleavage & blastocyst?+
Cleavage divides the conceptus into smaller blastomeres. Morula is a compact cell cluster. Blastocyst has a cavity, inner cell mass and outer trophoblast.
02Which blastocyst component forms the embryo proper?+
The inner cell mass (embryoblast); trophoblast contributes to extraembryonic structures including the fetal component of the placenta.
