Q1 · Histology
EasyExplanation
The trachea is lined by pseudostratified ciliated columnar epithelium with goblet cells, the classic respiratory epithelium. Every nucleus sits at a different height, which makes it look layered, but all cells reach the basement membrane. The cilia and mucus together form the mucociliary escalator that clears particles upward.
Q2 · Histology
EasyExplanation
Transitional epithelium, or urothelium, lines the urinary tract from the renal calyces to the proximal urethra. Its umbrella cells flatten as the bladder fills, letting the lining stretch without breaking, and its tight junctions keep urine from leaking into tissue. The oesophagus by contrast is stratified squamous non-keratinised.
Q3 · Histology
EasyExplanation
Type II pneumocytes are cuboidal cells that make and secrete surfactant, and they also act as the progenitor for both alveolar cell types after injury. Type I pneumocytes are thin squamous cells that cover about 95 per cent of the alveolar surface and handle gas exchange. Surfactant lowers surface tension and prevents alveolar collapse at end expiration.
Q4 · Histology
MediumExplanation
Purkinje fibres are modified cardiac myocytes that are larger and paler than working muscle, packed with glycogen and relatively sparse in myofibrils. That structure suits conduction rather than contraction and gives them the fastest conduction velocity in the heart. They remain cardiac muscle, so they keep their intercalated discs and striations.
Q5 · Histology
MediumExplanation
Adjacent Sertoli cells are joined by tight junctions that divide the seminiferous tubule into a basal and an adluminal compartment. This isolates developing germ cells from the immune system, which matters because meiotic cells express antigens the body has never seen. Leydig cells sit outside the tubule in the interstitium and secrete testosterone.
Histology sits within Anatomy, which carries the same syllabus in both exams. This set runs to 5 questions, each tagged Easy, Medium or Hard.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Histology marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Anatomy examiners keep returning to.
FAQ
Yes. Every question and explanation in this Histology set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Histology sits within Anatomy, which appears in the same form in both syllabuses. Gross anatomy, neuroanatomy, embryology and histology, the four areas NEET PG returns to every year. Nerve injuries, foramina and blood supply carry most of the marks.
