Frequently asked questions

Which model organism is asked most — earthworm, cockroach, or frog?

Cockroach anatomy (digestive and nervous system) is the most frequently tested of the three, followed by earthworm.

What tissue topic comes up most often?

Epithelial tissue classification (simple vs compound, by cell shape) and the structural differences between the three muscle types are the most recurring sub-topics.

Do I need to know internal anatomy diagrams in detail?

Yes — labelled-diagram recognition for cockroach digestive and nervous systems specifically has appeared in multiple past NEET papers.
