The major nerves supplying sympathetic innervation to the abdomen. The greater, lesser, and lowest (or smallest) splanchnic nerves are formed by preganglionic fibers from the spinal cord which pass through the paravertebral ganglia and then to the celiac ganglia and plexuses. The lumbar splanchnic nerves carry fibers which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia.

belong to the great sympathetic, and are two in number on each side. They are distinguished into: - 1. The great splanchnic nerve, (F.) Grand surrinal (Ch.), Its roots-four or five in number-come from the 6th, 7th, 8th, 9th, and sometimes the 10th, thoracic ganglia. They descend inwards, on the sides of the vertebral column, beneath the plenra, and unite into a single trunk, which enters the abdomen through a separation of the fleshy fibres of the pillars of the diaphragm; passes behind the stomach, and divides into several branches, which pass into the semilunar ganglion. 2. The lesser splanchnic nerve, Renal nerve, (F.) Splanchnique accessoire of Walther, Petit surrenal, (Ch.,) is composed of two distinct branches, proceeding from the 10th and 11th thoracic ganglia, which unite on the 12th dorsal vertebra into a cord, that pierces the diaphragm singly; enters the abdomen, and divides into two branches, one of which anastomoses with the greater splanchnic nerve, whilst the other sends its filaments to the renal and solar plexuses.

Proto Oncogene Proteins c erbB 2
- cell surface protein-tyrosine kinase that is found to be overexpressed in significant number adenocarcinomas. It has extensive homology can heterodimerize EGF EPIDERMAL GROWTH FACTOR), 3 receptor (RECEPTOR, 3) and the 4 receptor. Activation of erbB-2 receptor occurs during heterodimer formation with a ligand-bound erbB family members. EC 2.7.11.-.
