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.

Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
Kehr's sign is the occurrence of acute pain in the tip of the shoulder due to the presence of blood or other irritants in the peritoneal cavity when a person is lying down and the legs are elevated. Kehr's sign in the left shoulder is considered a classic symptom of a ruptured spleen. [1][2] May result from diaphragmatic or peridiaphragmatic ...
Fitz-Hugh–Curtis syndrome occurs almost exclusively in women, though it can be seen in males rarely. [5] It is complication of pelvic inflammatory disease (PID) caused by Chlamydia trachomatis (Chlamydia) or Neisseria gonorrhoeae (Gonorrhea) though other bacteria such as Bacteroides, Gardnerella, E. coli and Streptococcus have also been found to cause Fitz-Hugh–Curtis syndrome on occasion.

Congestive hepatopathy, is liver dysfunction due to venous congestion, usually due to congestive heart failure. The gross pathological appearance of a liver affected by chronic passive congestion is "speckled" like a grated nutmeg kernel; the dark spots represent the dilated and congested hepatic venules and small hepatic veins.
Shoulder problems including pain, are one of the more common reasons for physician visits for musculoskeletal symptoms. The shoulder is the most movable joint in the body. However, it is an unstable joint because of the range of motion allowed. This instability increases the likelihood of joint injury, often leading to a degenerative process in ...
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 a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein .
Liver sinusoidal endothelial cell. Liver sinusoidal endothelial cells (LSECs) form the lining of the smallest blood vessels in the liver, also called the hepatic sinusoids. LSECs are highly specialized endothelial cells with characteristic morphology and function. They constitute an important part of the reticuloendothelial system (RES).
