- A. Elie Metchnikoff
- B. Celsus
- C. Virchow
- D. None of the above
Explanation: Elie Metchnikoff discovered phagocytosis while studying the uptake of particles by mobile cells in starfish larvae.
Correct answer: Elie Metchnikoff- A. Lymphocytes
- B. Vacuolated Histocytes
- C. Plasma cells
- D. NeutrophilsConsult Online Doctors
Explanation: Lepra cells are foamy macrophages packed with Mycobacterium leprae and lipid, giving them a vacuolated appearance.
Correct answer: Vacuolated Histocytes- A. Monocytes
- B. Lymphocytes
- C. PMN's
- D. Eosinophils
Explanation: Suppuration is mainly produced by neutrophils, whose lysosomal enzymes digest tissue and form pus.
Correct answer: PMN's- A. Transudation -> exudation -> oedena
- B. Oedema -> exudation
- C. Exudation -> transudation -> oedema
- D. Only by exudation -> oedema
Explanation: In acute inflammation, increased hydrostatic pressure may first produce a protein-poor transudate; increased vascular permeability then…
Correct answer: Transudation -> exudation -> oedena- A. All of the above
- B. Leprosy
- C. Tuberculosis
- D. Sarcoidosis
Explanation: Sarcoidosis, leprosy, and tuberculosis all produce granulomatous inflammation, characterized by collections of activated macrophages…
Correct answer: All of the above- A. T cells
- B. B cells
- C. MonocyteConsult Online Doctors
- D. Plasma cells
Explanation: Epithelioid cells and multinucleated giant cells in a granuloma arise from activated macrophages, which are derived from monocytes.
Correct answer: MonocyteConsult Online Doctors- A. Arachidonic acid is metabolized to form prostaglandins and leukotrienes
- B. Leukotrienes cause bronchoconstriction
- C. COX is induced by cytokines at the site of inflammation
- D. COX-1 is inducible in many tissues
Explanation: COX-1 is generally constitutive and maintains normal gastric, renal and platelet functions, whereas inducible COX-2 is increased by…
Correct answer: COX-1 is inducible in many tissues- A. Tuberculosis
- B. Viral infections
- C. Tyhoid
- D. AmoebiasisTrack Health Symptoms
Explanation: Caseation is a cheese-like form of necrosis classically produced by Mycobacterium tuberculosis within tuberculous granulomas.
Correct answer: Tuberculosis- A. Tuberculoid leprosy
- B. Lepromatous leprosy
- C. Histoid leprosy
- D. Intermediate leprosy
Explanation: Lepra cells are foamy macrophages packed with Mycobacterium leprae and are abundant in lepromatous leprosy, where cell-mediated immunity…
Correct answer: Lepromatous leprosy- A. Exudative
- B. Granulomatous
- C. Necrotizing
- D. Cytopathic
Explanation: Granulomatous inflammation is a pattern of chronic inflammation involving persistent macrophage activation, not a typical acute…
Correct answer: Granulomatous- A. RNA template
- B. Rough endoplasmic reticulum
- C. Polyunsaturated fatty acids
- D. None of the above
Explanation: Prostaglandins are lipid mediators formed from membrane polyunsaturated fatty acids, especially arachidonic acid, through the…
Correct answer: Polyunsaturated fatty acids- A. A specific type of chronic inflammation
- B. Accumulation of modified macrophages
- C. Initiated by a number of infectious and non infectious agents
- D. A reaction of acute inflammationTrack Health Symptoms
Explanation: A granuloma is a specialised form of chronic inflammation consisting mainly of aggregated epithelioid macrophages, often with giant cells…
Correct answer: A reaction of acute inflammationTrack Health Symptoms- A. Sulfatide
- B. Surface glycolipids
- C. Hetero polysaccharide
- D. Sulfadase
Explanation: Surface glycolipids of Mycobacterium tuberculosis contribute to macrophage activation and the granulomatous response.
Correct answer: Surface glycolipids- A. Coagulase
- B. Peroxidase
- C. Hyaluronidase
- D. Bradykinin
Explanation: Hyaluronidase breaks down hyaluronic acid in connective tissue, allowing organisms and inflammatory fluid to spread through tissue, so it…
Correct answer: Hyaluronidase- A. Tuberculosis
- B. SarcoidosisTry Prep Courses
- C. Syphilis
- D. Granulation tissue
Explanation: Epithelioid cells are activated macrophages typical of granulomas in tuberculosis, syphilis and sarcoidosis.
Correct answer: Granulation tissue- A. Formation of blood cloth
- B. Organization
- C. Epithelial changes
- D. Acute inflammatory response
Explanation: The earliest event in healing of a clean wound is formation of a blood clot, which seals the defect and provides a provisional matrix.
Correct answer: Formation of blood cloth- A. Nutrition
- B. All of the aboveConsult Injury Lawyers
- C. Size and location of wound
- D. Adequate blood supply
Explanation: Healing requires adequate nutrition, especially protein, good blood supply and oxygen, and is also affected by the wound's size and…
Correct answer: All of the aboveConsult Injury Lawyers- A. Fibroblast
- B. Macrophages
- C. Polymorphs
- D. Budding blood vessels
Explanation: The essential components of granulation tissue are proliferating fibroblasts, newly formed capillaries and inflammatory cells such as…
Correct answer: Polymorphs- A. Steroids
- B. Protein
- C. Vitamin C
- D. Adequate oxygen supply
Explanation: Protein, vitamin C and adequate oxygen support collagen synthesis and tissue repair.
Correct answer: Steroids40. Regeneration by sprouting of axons takes place in which end of transaction of nerve_____________?
- A. Distal end
- B. Proximal end
- C. Both A and B
