The plexus receives pre-ganglionic parasymathetic afferents primarily [1] from the anterior vagal trunk, [1] [2] with a lesser contribution from [1] the posterior vagal trunk. [1] [2] The anterior vagal trunk issues one or more hepatic branches of anterior vagal trunk that pass in the superior portion of the lesser omentum to reach the hepatic plexus.
A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.
The hepatic branches of anterior vagal trunk are branches of the anterior vagal trunk that provide parasympathetic innervation the liver, [1] [2]: 499 and gallbladder. [2]: 266 Each anterior vagal trunk (it may be doubled or tripled) issues 1-2 hepatic branches which pass through the superior part of the omentum minus to reach and join the hepatic (nervous) plexus [2]: 250–252 before ...
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 capillary network, and a central vein .
The hepatic vein subsequently drains into the inferior vena cava. The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein .
These neurons are collected into two plexuses – the myenteric (or Auerbach's) plexus that lies between the longitudinal and the smooth muscle layers, and the submucosal (or Meissner's) plexus that lies between the circular smooth muscle layer and the mucosa. [38] [39] [40] Parasympathetic innervation to the ascending colon is supplied by the ...
Goss was the esteemed editor of the 25th edition of the seminal classic Gray’s Anatomy. Internationally lauded as the authority on all things anatomical, Gray’s Anatomy had been considered essential for any would-be physician to own since it was first published in London in 1858. It was written by Dr. Henry Gray and illustrated by Henry ...
The right lobe is functionally separated from the left lobe by the middle hepatic vein. From a functional perspective (one that takes the arterial, portal venous, and systemic venous anatomy into account) the falciform ligament separates the medial and lateral segments of the left hepatic lobe. [6] The right lobe is of a somewhat quadrilateral ...
