2023年8月8日 · These portal canals are composed of the portal triads, which are surrounded by loose stromal connective tissue. A periportal space ( space of Mall ), where lymph is produced, is sandwiched between the connective tissue of the portal canals and the hepatocytes.

In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of portal triads, hepatocytes arranged in linear cords between a …

Scanning electron microscopy (SEM) of a portal triad in the liver. The following three vessels are bundled together and found at the corners of the hexagonally shaped hepatic lobules. A continuous wall of hepatocytes surrounds the portal area. The term “portal triad” is a bit of a misnomer because it implies only three components.

In this LIVER virtual slide, identify the following: Lobule, roughly hexagonal in cross section. Central vein, in the center of a lobule. Hepatic triad (at each of a lobule’s corners) and its three components: A branch of the hepatic portal vein. A branch of …

Histology of the liver - lobules, central veins, hepatocytes, portal triads (hepatic arteries, portal venules, bile ductules), and bile ducts.

Scanning electron micrograph (SEM) of a portal triad in the liver. A distinctive component of a hepatic lobule found running along each of the lobule’s corners. Portal triads are composed of branches of three vessels: Red blood cells can be seen in …

With low magnification, locate a set of portal areas (triads) outlining a lobule. With higher power, identify the central venule in the center of the lobule and the triad of components in the portal area, namely branches of the hepatic portal vein (PV), hepatic artery (HA), and bile ductules (BD).

A distinct histological characteristic found within liver tissue is the presence of portal triads (hepatic triads, liver triads) at the “corners” of interlobular septa.

ITPR exists as three isoforms (displaying 70% homology), encoded each by a different gene, and assembles into the ER membrane as homo-or hetero tetramers. In the liver, ITPR1 and ITPR2 are highly...

LABORATORY 25- LIVER, GALLBLADDER AND PANCREAS OBJECTIVES: LIGHT MICROSCOPY: Liver: Recognize each component of liver lobules including hepatocytes, portal canals (tract) and the structures it contains (portal vein, hepatic artery, bile duct, lymphatics and nerve). Understand the structure of the plates of hepatocytes,
