The epithelial cells lining striated intralobular ducts:

Correct Answer: D

Rationale: The correct answer is D because epithelial cells lining striated intralobular ducts are usually simple cuboidal or columnar cells (A), have eosinophilic cytoplasm containing numerous mitochondria for energy production (B), and have basal cell membranes extensively folded to increase the surface area for active ion pump molecules (C). Choice A describes the cell morphology, choice B relates to cytoplasm content, and choice C pertains to membrane structure, all of which are characteristics of these cells. Therefore, selecting all three choices (D) accurately describes the features of epithelial cells in striated intralobular ducts.

Correct Answer: D

Rationale: The correct answer is D: adipocyte. Adipocytes are not typical of lamina propria, which is a loose connective tissue found in mucous membranes. Adipocytes are fat cells, primarily found in adipose tissue, not in the lamina propria. Lymphocytes (A), fibroblasts (B), and macrophages (C) are all commonly found in the lamina propria. Lymphocytes are involved in the immune response, fibroblasts produce collagen and extracellular matrix, and macrophages are phagocytic cells that help in defense and tissue repair. In summary, adipocytes do not belong in the lamina propria as they are not typical connective tissue cells found in this specific tissue layer.

Correct Answer: D

Rationale: The intensely basophilic bodies in the epithelial lining of intestinal crypts represent condensed chromatin of mitotic figures. This is because during mitosis, chromatin condenses into visible bodies which are basophilic due to their high DNA content. These bodies are typically located towards the apical end of columnar cells where active cell division occurs. Explanation for the other choices: A: Mucus vesicles are typically seen as clear, not basophilic, in histological sections. B: Ribosomes are not typically visible as distinct bodies in H&E stained sections and are not basophilic. C: Chylomicrons are lipid droplets and are not basophilic bodies found in the epithelial lining.

Correct Answer: C

Rationale: The correct answer is C because a hepatic cord refers to a row of adjacent hepatocytes within a liver lobule, which are the functional units of the liver responsible for various metabolic functions. This structure is essential for liver function and is where processes like detoxification and metabolism occur. Choice A is incorrect because a hepatic cord is not another name for a branch of the portal vein. Choice B is incorrect because the tough connective tissue surrounding a portal triad is known as Glisson's capsule, not a hepatic cord. Choice D is incorrect as a hepatic cord is not a branch of the bile duct. Overall, understanding the anatomical structure and function of the liver is crucial in determining the correct answer.

Correct Answer: D

Rationale: Kupffer cells are specialized macrophages located in the liver sinusoids. They play a crucial role in immune responses and detoxification. The correct answer is D (macrophages) because Kupffer cells share similar functions, morphology, and origin with macrophages, both being phagocytic cells derived from monocytes. Lymphocytes (A) are a type of white blood cell involved in adaptive immune responses, hepatocytes (B) are liver parenchymal cells responsible for various metabolic functions, and neutrophils (C) are another type of white blood cell primarily involved in innate immune responses.
