Directive word: Discuss
This question asks you to discuss. The directive word signals the depth of analysis expected, the structure of your answer, and the weight of evidence you must bring.
See our UPSC directive words guide for a full breakdown of how to respond to each command word.
How this answer will be evaluated
Approach
The directive 'discuss' requires a balanced exposition of facts with critical commentary across all five sub-parts. Allocate approximately 30 words (20% time) per sub-part, ensuring each response has a mini-introduction, core content with anatomical/physiological/pathological details, and a brief clinching statement. Prioritize precision over elaboration given the severe word constraint; avoid overlapping content between sub-parts.
Key points expected
- (a) Sweat glands: Structure (simple tubular, apocrine/eccrine distribution in species), thermoregulatory function, species variation (horses abundant, cattle/poorly developed), and role in electrolyte balance
- (b) Antimuscarinic agents: Atropine/glycopyrrolate mechanism (M-receptor blockade), pre-anaesthetic indications (salivary/bronchial secretion reduction, vagal blockade), side effects (tachycardia, ileus), and species-specific considerations
- (c) Hypocalcemic tetany: Parturient paresis pathophysiology (abrupt Ca demand vs. PTH response failure), clinical signs (recumbency, S-bend neck, subnormal temperature), and emergency therapy (IV calcium borogluconate with cardiac monitoring)
- (d) Thiamine deficiency: Polioencephalomalacia etiology (thiaminase in raw fish/bracken fern, amprolium antagonism), neurological signs (star-gazing, opisthotonus, blindness), and therapeutic response to thiamine HCl
- (e) Rabies neurological implications: Negri bodies pathognomonic significance, ascending paralysis progression, behavioral changes (furious vs. dumb form), zoonotic implications, and OIE/WHO One Health relevance in Indian context
Evaluation rubric
| Dimension | Weight | Max marks | Excellent | Average | Poor |
|---|---|---|---|---|---|
| Demand-directive understanding | 15% | 7.5 | Demonstrates precise grasp of 'discuss' by presenting structured, analytical exposition for each sub-part—not mere listing; for (b) evaluates both benefits and risks of antimuscarinics; for (c) integrates pathophysiology with clinical management; maintains critical stance rather than descriptive only | Provides factual coverage for all five parts but treats directive as 'describe' or 'list'; limited critical engagement; some sub-parts receive disproportionate attention | Misinterprets directive as 'define' or 'enumerate'; omits one or more sub-parts entirely; fails to distinguish between explanatory and evaluative components required |
| Content depth & accuracy | 25% | 12.5 | Displays command-level accuracy: for (a) distinguishes apocrine/eccrine distribution across livestock species; for (b) specifies glycopyrrolate's quaternary ammonium advantage over atropine; for (c) cites serum calcium thresholds (<8 mg/dL); for (d) identifies thiaminase sources relevant to Indian poultry systems; for (e) correlates limbic system involvement with behavioral rabies forms | Broadly correct information with minor errors (e.g., conflating sweat gland types, misstating antimuscarinic receptor specificity); adequate but not precise quantitative data; generic pathophysiology without species-specific nuance | Significant factual errors (e.g., stating cattle have abundant sweat glands, confusing thiamine with vitamin E deficiency, describing rabies as non-neurological); omission of core mechanistic explanations |
| Structure & flow | 20% | 10 | Each 150-word segment follows disciplined architecture: (a) anatomical foundation → functional integration → species adaptation; (b) pharmacodynamics → clinical application → cautions; (c) etiology → pathogenesis → diagnosis → treatment; (d) dietary antagonism → biochemical lesion → neurological sequelae; (e) viral neurotropism → pathological hallmarks → public health interface; seamless inter-part transitions | Clear labeling of sub-parts (a)-(e) with recognizable internal organization; some parts lack logical progression (e.g., jumping from signs to etiology without pathogenesis); occasional word-count imbalance favoring one part | Disorganized or fused sub-parts; stream-of-consciousness presentation; failure to demarcate responses; severe asymmetry (e.g., 80 words for one part, 220 for another); missing structural components like clinical signs or treatment |
| Examples / case-law / data | 20% | 10 | Integrates high-yield specifics: for (a) cites horse as model sweat gland species vs. buffalo dependence on wallowing; for (b) references atropine-induced ileus risk in horses; for (c) mentions NDRI Karnal studies on calcium metabolic profiles; for (d) notes amprolium toxicity in broiler operations; for (e) cites ARV (anti-rabies vaccine) Schedule in India post-exposure protocol | Generic species references without institutional or epidemiological anchoring; occasional mention of Indian conditions but lacking specificity; no quantitative data (incidence, prevalence, therapeutic dosages) | No examples, institutional references, or Indian context; entirely textbook reproduction; failure to connect (e) with national rabies elimination program or veterinary public health mandate |
| Conclusion & analytical edge | 20% | 10 | Each sub-part terminates with synthesizing insight: (a) sweat glands as evolutionary adaptation to domestication; (b) balanced antimuscarinic use in modern balanced anesthesia; (c) preventive dietary calcium strategies reducing economic loss; (d) feed quality assurance in intensive poultry; (e) rabies as exemplar of successful veterinary-public health integration with 'One Health' implications; demonstrates cross-cutting physiological principles | Brief concluding statements per sub-part but largely summative rather than analytical; no explicit connection between parts; misses opportunity to highlight comparative physiology or therapeutic evolution | Abrupt endings without closure; no concluding statements; failure to extract broader significance; treats five isolated facts rather than integrated physiological and clinical veterinary knowledge system |
