Question

Identify the given structure?

• A. Lymph node
• B. Glomerulus
• C. Spleen
• D. Pancreatic islet cells

Answer 1

The Correct Option is D

The image shows a structure that can be identified as Pancreatic islet cells. These are regions of the pancreas containing endocrine (hormone-producing) cells. These cells are crucial for maintaining glucose homeostasis in the body as they produce important hormones like insulin and glucagon. Pancreatic islet cells are characterized by their distinct grouping pattern and endocrine function, differentiating them from other structures like the lymph nodes, glomerulus, or spleen.

Option	Explanation
Lymph node	Lymph nodes are small, bean-shaped structures that are part of the lymphatic system; they typically do not have the endocrine characteristics displayed by pancreatic islet cells.
Glomerulus	The glomerulus is a network of capillaries located at the beginning of a nephron in the kidney, which differs significantly in appearance and function compared to pancreatic islet cells.
Spleen	The spleen is an organ involved in the immune response and recycling of red blood cells; it lacks the distinctive groupings of cells found in pancreatic islets.
Pancreatic islet cells	Hormone-producing cells in the pancreas that play a crucial role in regulating blood sugar levels; they are responsible for producing insulin, glucagon, and other hormones.
