ALPHA CELL Meaning and
Definition
-
An alpha cell, also known as an A cell, is a type of specialized endocrine cell found in the pancreas, which is a large organ located in the abdomen. Alpha cells are primarily responsible for producing and secreting a hormone called glucagon. This hormone plays a crucial role in maintaining normal blood sugar levels in the body.
Alpha cells are part of the islets of Langerhans, which are clusters of endocrine cells within the pancreas. These cells are scattered throughout the pancreas and account for about 20% of the total number of cells in the islets. Alpha cells are identifiable by their unique characteristics, including a pale staining cytoplasm and irregular shape.
The main function of alpha cells is to monitor and respond to changes in blood glucose levels. When blood sugar levels decrease, alpha cells secrete glucagon into the bloodstream. Glucagon acts to counter the effects of insulin, another hormone produced by the pancreas. It signals certain cells in the liver to release stored glucose, increasing blood sugar levels.
In summary, an alpha cell is an endocrine cell found in the pancreas that produces and releases the hormone glucagon. These cells play a vital role in regulating blood sugar levels and help maintain the body's overall metabolic balance.
