They are divided into three groups: inferior – inferior of the saphenous opening of the leg, receive drainage from lower legs; superolateral – on the side of the saphenous opening, receive drainage from the side buttocks and the lower abdominal wall.
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
The ileocolic lymph nodes, from ten to twenty in number, form a chain around the ileocolic artery, but tend to subdivide into two groups, one near the duodenum and the other on the lower part of the trunk of the artery. Where the vessel divides into its terminal branches the chain is broken up into several groups:
They receive their afferents from the stomach; their efferents pass to the celiac group of preaortic lymph nodes. The inferior gastric lymph nodes (Latin: lymphoglandulæ gastricæ inferiores ; right gastroepiploic lymph nodes), four to seven in number, lie between the two layers of the greater omentum along the pyloric half of the greater ...
Visceral nodes of the abdominal cavity. The hepatic lymph nodes consist of the following groups: (a) hepatic, on the stem of the hepatic artery, and extending upward along the common bile duct, between the two layers of the lesser omentum, as far as the porta hepatis; the cystic gland, a member of this group, is placed near the neck of the gall-bladder;
Their principal afferents are derived from the inguinal lymph nodes, the deep lymphatics of the abdominal wall below the umbilicus and of the adductor region of the thigh, and the lymphatics from the glans penis, glans clitoridis, the membranous urethra, the prostate, the fundus of the urinary bladder, the cervix uteri, and upper part of the ...
the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side) of hips; the pubic region encompassing the area above the genitals. The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen,
The periaortic lymph nodes (also known as lumbar) are a group of lymph nodes that lie in front of the lumbar vertebrae near the aorta. These lymph nodes receive drainage from the gastrointestinal tract and the abdominal organs. The periaortic lymph nodes are different from the paraaortic lymph nodes. The periaortic group is the general group ...
