Illustration of islet of Langerhans in pancreas

Illustration of an islet of Langerhans, a group of specialised cells that forms the endocrine component of the human pancreas. About one million islets are scattered throughout the pancreas. Some 3, 000 cells in each islet secrete a variety of hormones. The most numerous are the insulin- producing (beta) cells (with blue cytoplasmic bodies) which secrete the hormone directly into the bloodstream. Insulins main role is in controlling the transport of glucose; insulin deficiency results in diabetes. Other hormones secreted by other cells in the islet include glucagon, pancreatic polypeptide, and somatostatin

Beta Cell Insulin Islet Of Langerhans Pancreas

EDITORS COMMENTS
This print showcases an intricate illustration of the islet of Langerhans in the pancreas, shedding light on the remarkable complexity of our body's endocrine system. Comprising a multitude of specialized cells, these islets are scattered throughout the pancreas in staggering numbers, with approximately one million present. Within each islet, around 3,000 cells work harmoniously to secrete various hormones crucial for maintaining our overall health. The dominant players within these islets are the insulin-producing (beta) cells portrayed here with their distinctive blue cytoplasmic bodies. These remarkable cells release insulin directly into the bloodstream, playing a pivotal role in regulating glucose transport throughout our bodies. Any deficiency in insulin production can lead to diabetes and its associated complications. Beyond insulin production, other vital hormones such as glucagon, pancreatic polypeptide, and somatostatin are also secreted by different cell types within these islets. Together, this symphony of hormonal activity ensures proper metabolic balance and contributes significantly to our well-being. This awe-inspiring artwork not only provides a glimpse into the inner workings of our anatomy but also serves as a testament to human ingenuity in unraveling complex biological processes. It reminds us that even at microscopic levels, there exists an intricately woven tapestry that governs our bodily functions – a true marvel worth exploring and understanding further.
