SPIGELIAN LOBE Meaning and
Definition
-
The Spigelian lobe is a term used in anatomy to refer to a distinct portion of the liver. It is named after Adriaan van den Spieghel, a Flemish anatomist from the 16th century who first described it. The Spigelian lobe is also sometimes known as the caudate process or the Spiegelian process.
Located on the posterior surface of the liver, the Spigelian lobe is situated between the liver's right lobe and the gallbladder fossa. It is a small, tongue-shaped projection that extends from the main body of the liver towards the gallbladder.
The Spigelian lobe is characterized by its unique anatomical features, including its separate blood supply and bile drainage. It receives blood from both the hepatic artery and the portal vein. Bile, produced by the liver cells, also drains from this lobe into the common bile duct, which then carries it into the small intestine.
While the Spigelian lobe is smaller in size compared to the main lobes of the liver, it plays an important role in the overall function of the organ. Its distinct blood supply and bile drainage allow for efficient processing and transportation of nutrients, as well as clearance of waste products from the body.
Understanding the anatomy and function of the Spigelian lobe is crucial for medical professionals, as it can affect diagnoses and treatment plans for individuals with liver-related conditions.
