Pancreatic Islet Alpha Cell

Endocrine cells located in the pancreatic islets, primarily responsible for synthesizing and secreting glucagon.

Key Functions:

• Produces and secretes glucagon in response to low blood glucose levels.
• Raises blood glucose by stimulating glycogenolysis and gluconeogenesis in the liver.
• Plays a central role in regulating glucose homeostasis.

Interacting Systems & Components:

• Pancreatic Islet (component of)
• Glucagon (produces)
• Pancreas (located in)
• Liver (targets)
• Endocrine System (component of)
