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 DSM-5 allows for diagnosis of the predominantly inattentive presentations of ADHD (ICD-10 code F90.0) if the individual presents six or more (five for adults) of the following symptoms of inattention for at least six months to a point that is disruptive and inappropriate for developmental level:
Congenital hepatic fibrosis is an inherited fibrocystic liver disease associated with proliferation of interlobular bile ducts within the portal areas and fibrosis that do not alter hepatic lobular architecture. The fibrosis would affect resistance in portal veins leading to portal hypertension. [citation needed]
Although Weikard mainly described a single disorder of attention resembling the combined presentation of ADHD, Crichton postulates an additional attention disorder, described as a "morbid diminution of its power or energy", and further explores possible "corporeal" and "mental" causes for the disorder (including "irregularities in diet ...
The quadrate lobe is an area of the liver situated on the undersurface of the medial segment left lobe (Couinaud segment IVb), bounded in front by the anterior margin of the liver, behind by the porta hepatis, on the right by the fossa for the gall-bladder, and on the left by the fossa for the umbilical vein.
Hyperkinetic disorder was a neuropsychiatric condition that was thought to emerge in early childhood. Its features included an enduring pattern of severe, developmentally-inappropriate symptoms of inattention, hyperactivity, and impulsivity across different settings (e.g., home and school) that significantly impair academic, social, and work performance. [1]
Inattention is a more common presentation in adult ADHD, manifesting as difficulty starting and completing tasks, forgetfulness, difficulty focusing, disorganization, and persistent tardiness. [7] [10] A combined presentation is a combination of hyperactivity, inattention, and impulsiveness. [11] ADHD can only be diagnosed by a licensed ...
The right vertical limb of the "H" defines the left and right functional lobes, while the left vertical limb of the "H" defines the right and left anatomical lobes. The horizontal line between the vertical limbs of the "H" represents the porta hepatis. The quadrate and caudate lobe lie superior and inferior to this line respectively.
