Cells in the pancreas that produce insulin are :

Appeared in: IGNOU PB Bsc Entrance-2023

Explanation

  • The pancreas has both exocrine (digestive) and endocrine (hormonal) functions.
  • The endocrine functions are carried out by clusters of specialized cells known as the Islets of Langerhans, or islet cells.
  • Within these islets, beta (β) cells are specifically responsible for synthesizing and secreting insulin.
  • Insulin is a key hormone that lowers blood glucose levels by facilitating the uptake of glucose into body cells.

Why Other Options Were Wrong

  • Option A: Epithelial cells are primarily lining and covering cells. While they line the pancreatic ducts, they do not have an endocrine function to produce hormones like insulin.
  • Option C: Hepatic cells, or hepatocytes, are the primary functional cells of the liver, not the pancreas. Their main roles are in metabolism, detoxification, and bile production.
  • Option D: Germ cells are reproductive cells (sperm in males, ova in females) involved in creating a new organism. They have no role in metabolic regulation or insulin production.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Endocrine function of the pancreas and insulin production as background academic context rather than a clinical decision trigger.
  • Understanding the function of islet cells is fundamental to understanding Diabetes Mellitus. In Type 1 Diabetes, the body's immune system destroys the beta cells, leading to an absolute insulin deficiency.
  • In Type 2 Diabetes, the body either doesn't produce enough insulin or the body's cells become resistant to insulin's effects.
  • Nurses play a critical role in managing diabetes, which includes administering insulin, monitoring blood glucose levels, and educating patients about diet, exercise, and medication.
How to Approach the Question
  • First, identify the key terms in the question: 'pancreas' and 'produce insulin'.
  • This is a factual recall question from anatomy and physiology.
  • Recall the dual function of the pancreas: exocrine (digestion) and endocrine (hormones).
  • Remember that insulin is a hormone that regulates blood sugar.
  • Connect the endocrine function to the specific cell clusters in the pancreas, the Islets of Langerhans (islet cells).
  • Evaluate the options: eliminate cells from other organs (hepatic/liver cells) or with different functions (epithelial/lining cells, germ/reproductive cells) to arrive at the correct answer.
Concept Tested & Keywords
  • Concept Tested: Endocrine function of the pancreas and insulin production.
