A patient presented with acute abdominal pain. On clinical suspicion the patient underwent cholecystectomy. On histopathological examination the finding is normal. Which of the following type of cells line the gallbladder?
**Core Concept**
The question is testing the student's knowledge of the histological structure of the gallbladder. The gallbladder is a specialized organ that stores bile, and its lining is composed of a specific type of epithelial cell.
**Why the Correct Answer is Right**
The correct answer is **C. Pseudostratified columnar epithelium with goblet cells**. The gallbladder is lined by a type of epithelium that is specialized to secrete mucin and protect the underlying tissue from the alkaline bile. Pseudostratified columnar epithelium with goblet cells is the correct answer because it accurately describes the histological structure of the gallbladder lining. This type of epithelium is characterized by columnar cells with goblet cells interspersed throughout, giving it a pseudostratified appearance.
**Why Each Wrong Option is Incorrect**
**Option A:** Simple Cuboidal Epithelium is incorrect because it is found in structures such as the kidney collecting ducts and salivary glands, not the gallbladder.
**Option B:** Simple Squamous Epithelium is incorrect because it is found in structures such as the lungs and blood vessels, not the gallbladder.
**Option D:** Stratified Squamous Epithelium is incorrect because it is found in structures such as the skin and esophagus, not the gallbladder.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the histological structure of organs can sometimes be altered in disease states, and a normal histopathological examination does not always rule out a diagnosis. In this case, a normal histopathological examination may suggest that the patient's symptoms were not due to a gallbladder pathology.
**Correct Answer:** C. Pseudostratified columnar epithelium with goblet cells.
