The "pancreas of Aselli" refers to a pair of small elongated glands located adjacent to the small intestines in mammals, primarily humans, dogs, and cats. They are named after the Italian physician and anatomist, Gaspare Aselli, who first discovered and described them in 1627.
The pancreas of Aselli, also known as the accessory pancreas or glandulae pancreaticae accessoriae, consists of lobules of exocrine tissue and is typically found along the superior mesenteric artery. This accessory pancreas is distinct from the main pancreas located in the upper abdomen.
Functionally, the pancreas of Aselli plays a minor role compared to the primary pancreas. It produces and secretes digestive enzymes like amylase, lipase, and proteases into the proximal small intestine, aiding in the breakdown of carbohydrates, fats, and proteins. These enzymes are essential for proper digestion and nutrient absorption.
Although the pancreas of Aselli is not vital for digestion, it may occasionally cause medical complications. For example, inflammation or infection of this accessory pancreas can lead to abdominal pain, discomfort, or gastrointestinal disturbances. In rare cases, it may be necessary to surgically remove the accessory pancreas to alleviate symptoms or prevent further complications.
In conclusion, the pancreas of Aselli is a small accessory gland found near the small intestines, initially described by Gaspare Aselli. Its chief function is to produce and release digestive enzymes that aid in the digestion and absorption of nutrients, serving a supplemental role to the main pancreas.
