Mercury mostly affects__________________
- A.
PCT
- B.
DCT
- C.
Collecting duct
- D.
All
Correct Answer
A. PCTExplanation
Mercury mostly affects the Proximal Convoluted Tubule (PCT). The PCT is responsible for the reabsorption of important substances such as glucose, amino acids, and electrolytes from the filtrate back into the bloodstream. Mercury can interfere with this reabsorption process, leading to impaired kidney function and potential toxicity. It can also cause damage to the tubular cells of the PCT, disrupting its normal functioning. Therefore, the PCT is particularly susceptible to the harmful effects of mercury exposure.Rate this question:

Metastatic calcifications
- B.
Dystrophic calcifications
- C.
Gangrene
- D.
All
Correct Answer
B. DystropHic calcificationsExplanation
Psammoma bodies are microscopic structures that are commonly associated with dystrophic calcifications. Dystrophic calcifications occur in areas of tissue damage or necrosis, where calcium salts are deposited in response to cell death. Psammoma bodies are often found in certain types of tumors, such as papillary thyroid carcinoma, serous ovarian carcinoma, and meningioma, where they are formed by the accumulation of calcium salts. Therefore, the correct answer is dystrophic calcifications.Rate this question:

Clear cells are seen in
- A.
Ewings sarcoma
- B.
Chondrosarcoma
- C.
Osteosarcoma
- D.
Fibrosarcoma
Correct Answer
B. ChondrosarcomaExplanation
Chondrosarcoma is a type of bone cancer that arises from cartilage cells. Clear cells are a characteristic feature seen in chondrosarcoma, where the tumor cells have a clear cytoplasm due to the accumulation of mucinous material. This feature helps in distinguishing chondrosarcoma from other types of bone tumors such as Ewing's sarcoma, osteosarcoma, and fibrosarcoma, where clear cells are not typically observed. Therefore, the presence of clear cells is a key diagnostic feature of chondrosarcoma.Rate this question:

Fibrin degradation products are diagnostic in
- A.
Disseminated intravascular coagulation
- B.
Thrombocytopenic purpura
- C.
Sickle cell anemia
- D.
Hemophilia
Correct Answer
A. Disseminated intravascular coagulationExplanation
Fibrin degradation products are diagnostic in disseminated intravascular coagulation (DIC) because DIC is a condition characterized by widespread activation of the coagulation system, leading to the formation of blood clots throughout the body. As these blood clots are broken down, fibrin degradation products are released into the bloodstream. Therefore, the presence of fibrin degradation products indicates the ongoing breakdown of blood clots, which is a hallmark of DIC. Thrombocytopenic purpura, sickle cell anemia, and hemophilia are not typically associated with the widespread activation of the coagulation system seen in DIC.Rate this question:

Beta heavy chain disease
- B.
Delta heavy chain disease
- C.
Mu heavy chain disease
- D.
Epsilon heavy chain disease
Correct Answer
C. Mu heavy chain diseaseExplanation
Mu heavy chain disease is a rare type of B-cell lymphoma characterized by the production of abnormal mu heavy chains. These abnormal proteins, known as Bence Jones proteins, are detected in the urine of affected individuals. Unlike other heavy chain diseases listed, Mu heavy chain disease specifically presents with the presence of Bence Jones proteins. This distinguishes it from the other heavy chain diseases, making it the correct answer in this scenario.Rate this question:

Red infarcts are seen in
- A.
Heart
- B.
Spleen
- C.
Kidney
- D.
Lungs
Correct Answer
D. LungsExplanation
Red infarcts are seen in the lungs. Infarcts occur when blood supply to an organ or tissue is blocked, leading to tissue death. Red infarcts typically occur in organs with dual blood supply or when reperfusion occurs after an initial ischemic event. In the lungs, red infarcts can be seen due to the presence of collateral blood supply from the bronchial arteries. This allows for reperfusion and the development of red infarcts, which are characterized by hemorrhage into the infarcted tissue.Rate this question:

Necrotic epithelium with sloughing is seen in
- A.
Trauma
- B.
Aspirin burn
- C.
Chronic atrophic stomatitis
- D.
All
Correct Answer
B. Aspirin burnExplanation
Necrotic epithelium with sloughing is a characteristic finding in an aspirin burn. When aspirin comes into contact with the skin or mucous membranes, it can cause a chemical burn. This burn leads to the death of the surface epithelial cells, resulting in necrosis. The necrotic epithelium then sloughs off, leaving behind a raw and ulcerated area. This is why an aspirin burn is associated with the presence of necrotic epithelium with sloughing.Rate this question:

TB resulting in spinal curvature is known as?
- A.
Patey's disease
- B.
Pott's disease
- C.
Pet's disease
- D.
Moon's tumor
Correct Answer
B. Pott's diseaseExplanation
Pott's disease is a term used to describe tuberculosis (TB) that affects the spine, resulting in spinal curvature. It is named after Sir Percivall Pott, an English surgeon who first described the condition in the 18th century. TB can spread to the spine through the bloodstream or from nearby infected tissues, causing destruction of the vertebral bodies and leading to spinal deformities. Pott's disease can cause symptoms such as back pain, stiffness, and neurological deficits. Prompt diagnosis and treatment with anti-TB medications are crucial to prevent further damage to the spine and complications.Rate this question:

CD 1
- B.
CD 3
- C.
CD 7
- D.
CD 19
Correct Answer
D. CD 19Explanation
CD 19 is not a T cell marker because it is a B cell marker. CD 1, CD 3, and CD 7 are all T cell markers that help identify and distinguish different types of T cells. CD 19, on the other hand, is specifically expressed on B cells and is used to identify and characterize B cell populations.Rate this question:

Classical and alternate pathways of complement activation merge on?
- A.
C 3 complement
- B.
C 5 complement
- C.
C6 complement
- D.
None
Correct Answer
A. C 3 complementExplanation
The classical and alternate pathways of complement activation merge on the C3 complement. This is a crucial step in the complement cascade, where both pathways converge to activate C3. Once C3 is activated, it leads to the formation of the C5 convertase and the subsequent activation of the terminal pathway, resulting in the formation of the membrane attack complex (MAC) and the destruction of target cells. Therefore, the C3 complement plays a central role in the complement system, serving as a point of convergence for both pathways.Rate this question:
