Is cockroach in NEET syllabus? Not as a full topic any more: the current NEET UG syllabus from the National Medical Commission describes organ systems of one animal and names the frog, and the rationalised NCERT class 11 book removed the cockroach and earthworm sections from the Structural Organisation in Animals chapter. So the detailed morphology and anatomy of the cockroach that older batches learned is no longer something you need to master.
The confusion comes from one odd phrase. The syllabus line still says "an insect" and puts Frog in brackets, so many students wonder which animal is meant. This page explains the wording, what to study instead, and how to treat cockroach questions in older papers.

The exact syllabus wording and why it confuses people
In the biology part of the NEET UG syllabus, Unit 2 covers animal tissues and then the morphology, anatomy and functions of five body systems (the gut, blood circulation, breathing, nerves and reproduction) of "an insect (Frog)", with the note "brief account only".
A frog is an amphibian, not an insect. The word insect is left over from the older syllabus, which named the cockroach at this spot. When the syllabus was revised, the animal in brackets changed to frog but the word before it did not. Coaching notes and forums then argued over which one counts. The textbook settles it: the rationalised NCERT chapter keeps the frog and no longer has the earthworm and cockroach sections.
Is cockroach in NEET syllabus after the NCERT cuts?
The older Structural Organisation in Animals chapter studied three animals in detail. After NCERT's rationalisation, the deletion list for this chapter reads as follows:
| Section | Status |
|---|---|
| Earthworm: morphology and anatomy | Removed |
| Cockroach: morphology and anatomy | Removed |
| Animal tissues | Retained |
| Frog: morphology and anatomy | Retained |
That means topics like the cockroach's 13 chambered heart, its mosaic vision, the mushroom gland and the Malpighian tubule count you may see in old guides are no longer direct syllabus points.
Frog topics you should know instead
Since the chapter now gives the frog the space the three animals used to share, expect questions on each of its systems:
- General features: the common Indian frog, Rana tigrina; cold blooded nature, colour change, aestivation in summer and hibernation in winter
- Morphology: head and trunk, no neck or tail, webbed hind limbs, sexual dimorphism (vocal sacs and copulatory pad in males)
- Digestive system: the path from buccal cavity to cloaca, bilobed tongue, liver, gall bladder and pancreas
- Respiration: through the skin in water and through skin, buccal cavity and lungs on land
- Circulation: a three chambered heart with two atria and one ventricle, hepatic and renal portal systems
- Excretion: kidneys and urea as the main waste, so the frog is ureotelic
- Nervous system and senses: brain regions, ten pairs of cranial nerves, eyes, tympanum
- Reproduction: external fertilisation in water and development through a tadpole stage
Pair this with animal tissues (epithelial, connective, muscle, neural), which sits in the same chapter and is asked often. All ten biology units are mapped on our NEET biology syllabus page.
Where a cockroach can still appear
Dropping a section does not erase the animal from the whole book. Insects, and sometimes cockroaches by name, still turn up as examples in other chapters that remain on the syllabus. A few places to watch:
- Animal Kingdom: features of Arthropoda such as jointed legs, chitinous exoskeleton and an open circulatory system
- Excretion: Malpighian tubules as the excretory organs of most insects, an example NCERT links to cockroaches
- Breathing: tracheal tubes as the insect method of gas exchange
These are one line facts inside larger chapters. Learn them as part of those chapters, not as a separate cockroach topic.
Handling cockroach questions in older NEET papers
Past papers from before the revision include direct cockroach anatomy questions, and these still circulate in question banks. Skip them when you practise, or mark them as outside the current syllabus so they do not shake your confidence. Spend the saved time on frog and animal tissue questions, which are now the core of this chapter.
Our page on NEET previous papers explains how to use old papers when parts of the syllabus have changed.
Placing this chapter inside the whole paper
NEET UG has 180 compulsory questions, and half of them, 90, are biology, split between botany and zoology. Scoring is plus 4 per correct pick, with 1 subtracted per error. Structural Organisation in Animals is a small chapter in that picture, so give it a focused few days rather than weeks: read the NCERT text twice, draw the frog's heart and digestive system from memory, and solve chapter questions on tissues.
For the full exam structure, see the NEET syllabus, and for students still in class 11, the CBSE class 11 biology syllabus follows the same NCERT chapter.
Frequently asked questions
Is cockroach completely removed from NEET?
Its detailed morphology and anatomy has dropped out of what you must study, since NCERT deleted that section and the NEET syllabus names the frog. Cockroaches may still appear as passing examples in other chapters, such as insects with Malpighian tubules.
Why does the syllabus say 'insect (Frog)'?
It is a leftover word from the older version, which studied the cockroach at this point. The animal in brackets was changed to frog while the word insect stayed. Go by the animal named and the current NCERT chapter.
Is earthworm in the NEET syllabus?
The earthworm morphology and anatomy section was removed from the NCERT chapter along with the cockroach section, and the syllabus line does not name it. You do not need to study it as a separate topic.
Which frog topics are asked most?
Questions usually test the three chambered heart, modes of respiration, the excretory product, sexual dimorphism, and the parts of the digestive tract. Read the NCERT frog section line by line, since statement based questions draw on its exact wording.
Should I study cockroach from older books just in case?
It is not needed for the current syllabus. If you have spare time at the very end, a quick read does no harm, but frog and animal tissues deserve your attention first.
Where is the NEET syllabus officially published?
The syllabus is released with the NEET UG information bulletin on the official NEET website. Look under Biology, Unit 2.
