How to use these histology questions
These eight single-best-answer questions cover common ways of testing whether you can connect what you see in a tissue section with its structure and function. They are practice questions for biomedical science, not a claim about the format of any particular exam. If you are preparing for a named course or assessment, check its syllabus and guidance for the topics and question style it uses.
Choose an option in each question card, then read the explanation straight away. For every answer, name the visual clue that supports it. If you chose incorrectly, note whether the problem was identifying a structure, distinguishing similar cell types or recalling what a feature does. That tells you what to review rather than simply giving you a score.
The first card tests how epithelial structure relates to the mechanical demands of a surface. A MySummaries question card on that distinction looks like this:
A section of oesophagus shows several layers of cells. The superficial cells are flattened and retain nuclei; there is no surface keratin. Which epithelium is present?
The oesophagus is lined by non-keratinised stratified squamous epithelium, which protects against abrasion while remaining moist. Keratinised stratified squamous epithelium is the strongest distractor, but its surface layer is keratinised, as in the epidermis.
The key distinction is both the number of layers and the state of the surface cells. Stratified epithelium has multiple layers; squamous describes the flattened cells at the surface. Do not call every multilayered epithelium transitional: that term refers to the distensible lining of the urinary tract.
Gastric glands: identify the cell
This question tests whether cell appearance and secretion can be linked. In a routine stain, parietal cells tend to have abundant eosinophilic cytoplasm, while chief cells are often more basophilic because of their protein-synthesising machinery.
In a fundic gastric gland, a large cell has abundant eosinophilic cytoplasm and a central nucleus. Which cell is it, and what does it secrete?
Parietal cells secrete hydrochloric acid and intrinsic factor. Chief cells secrete pepsinogen and are the strongest distractor, but their basophilic cytoplasm reflects abundant rough endoplasmic reticulum and they are not the large eosinophilic cells described.
When distinguishing the two, keep the products paired with the cell: parietal—acid and intrinsic factor; chief—pepsinogen. A question may give function rather than colour, so learn both the identifying appearance and the secretion.
Small intestine: locate the secretory cell
The position of a cell within a tissue can be as useful as its shape. This item checks recognition of a specialised cell at the base of an intestinal crypt.
A small-intestinal section shows cells with prominent eosinophilic granules at the base of the crypts of Lieberkühn. Which cell type is present?
Paneth cells lie at the base of small-intestinal crypts and have conspicuous eosinophilic granules. Goblet cells are the strongest distractor because they are also secretory, but their pale mucin-filled cytoplasm is found among the epithelial cells rather than as granular cells at the crypt base.
Paneth cells contribute to innate defence, including through secretion of lysozyme and defensins. Keep the tissue landmarks straight: villi project into the lumen, whereas crypts are invaginations between the villi.
Cartilage: use matrix and location
This question uses the combination of a tissue location and a matrix feature. Focus on what the matrix contains, not just the fact that cells sit in lacunae; lacunae are found in more than one cartilage type.
A tracheal section contains chondrocytes in lacunae within a smooth, glassy matrix. Which cartilage type is this?
The tracheal rings are hyaline cartilage, with a smooth, glassy matrix rich in type II collagen. Elastic cartilage is the strongest distractor because it also contains chondrocytes in lacunae, but it has abundant elastic fibres and is found in structures such as the epiglottis and pinna.
Use location to narrow the possibilities, then confirm with the matrix. Fibrocartilage has prominent collagen bundles and is suited to resisting compression and tension; elastic cartilage has an elastic-fibre-rich matrix. Avoid identifying cartilage from lacunae alone.
Compact bone: read the organisation
A useful bone-section question asks you to recognise the arrangement of the tissue rather than simply name a cell. The central canal and concentric lamellae are the landmarks to find.
In a ground section of compact bone, which structure consists of concentric lamellae arranged around a central canal?
An osteon, or Haversian system, has concentric lamellae around a central canal containing vessels and nerves. A trabecula is the strongest distractor, but it is a strut of spongy bone rather than the concentric unit described.
Lacunae house osteocytes, and canaliculi are tiny channels connecting lacunae. These terms describe parts of bone organisation; they are not interchangeable names for an osteon.
Kidney: distinguish proximal from distal tubule
This question tests a common light-microscopy distinction. Compare the brush border, cytoplasm and lumen rather than relying on tubule size alone.
A renal tubule has strongly eosinophilic cells and a fuzzy, partly obscured lumen caused by a prominent apical brush border. Which segment is most likely?
The proximal convoluted tubule has abundant apical microvilli forming a brush border, giving the lumen a fuzzy appearance; its cells are often eosinophilic. The distal convoluted tubule is the strongest distractor, but it lacks a prominent brush border and usually has a clearer lumen.
A good identification combines two clues: brush border and a less distinct lumen. In a labelled or photographed section, also check where the tubule sits in relation to glomeruli and other structures, if that information is available.
Liver: recognise a portal tract
This item checks whether you can identify a group of structures by their relationship within connective tissue. The three components of the portal triad have different wall or lining features.
A connective-tissue area at the edge of a hepatic lobule contains a thin-walled vessel, a smaller thick-walled vessel and a duct lined by cuboidal cells. What is the duct?
A portal tract contains a bile duct lined by cuboidal epithelium, alongside a portal-vein branch and a hepatic-artery branch. The hepatic-artery branch is the strongest distractor because it is also present in the tract, but it is a vessel with a muscular wall, not an epithelial-lined duct.
The central vein is not part of the portal triad; it lies towards the centre of a classic lobule. A practical identification habit is to ask whether a structure has an epithelial lining or a vascular wall before naming it.
Lung: distinguish the alveolar cell types
The final question links a cell’s shape and organelle content to its role. It also separates the cell that produces surfactant from the very thin cell that forms most of the gas-exchange surface.
Which alveolar cell is cuboidal, contains lamellar bodies and secretes surfactant?
Type II pneumocytes are cuboidal cells that contain lamellar bodies and secrete surfactant. Type I pneumocytes are the strongest distractor because they line the alveoli, but they are thin squamous cells specialised for gas exchange rather than surfactant secretion.
Remember the functional pairing: type I cells provide a thin gas-exchange surface; type II cells produce surfactant and can contribute to repair of the alveolar epithelium. Macrophages are mobile phagocytic cells, not the epithelial source of surfactant.
Turn errors into a review plan
After answering, group missed questions by the kind of error. If you knew a structure but confused it with a similar one, make a comparison card. If you could not recognise the structure, return to a labelled image and practise describing its location, shape, staining and neighbouring features. If you identified it but did not know its function, connect the histological feature to the job it performs.
A review report can make the weakest topics visible across repeated practice:
Do not respond to a low percentage by rereading an entire textbook chapter automatically. First identify the precise confusion, then review a small set of relevant images and test the distinction again. A repeated error is a useful signal to turn into a focused prompt.
For example, a remediation card can isolate a distinction that has been missed more than once:
You lost this mark twice: what two features distinguish a proximal convoluted tubule from a distal convoluted tubule in routine light microscopy?
Answer in terms of visible evidence: the proximal tubule has an apical brush border and a less distinct lumen; the distal tubule lacks a prominent brush border and has a clearer lumen. Revisit the card until you can state both features without relying on a guess. Then check whether the same distinction holds when the section is rotated, crowded or less well stained.
