Sperm–oocyte interaction
Understand what you see.
Coordinated recognition and membrane events allow fertilization and help prevent polyspermy.
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.
- Corona radiata surrounds zona
- Zona surrounds oocyte membrane
- Cortical response follows fusion
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 do you identify sperm–oocyte interaction?+
Corona radiata surrounds zona. Zona surrounds oocyte membrane. Cortical response follows fusion.
02What is the cortical reaction?+
Release of cortical granules alters the zona and helps prevent additional sperm from fertilizing the oocyte.
03Is the acrosome a nucleus?+
No. It is a specialised cap-like organelle over the sperm head, distinct from its haploid nucleus.
04Which structures should you point out on this reference?+
Acrosome; Zona pellucida; Oocyte membrane. Coordinated recognition and membrane events allow fertilization and help prevent polyspermy.
