solar plexus(redirected from Celiac branches)
Also found in: Dictionary, Thesaurus, Medical.
(also celiac plexus), in humans, the aggregate of neural elements concentrated in the abdominal cavity at the origins of the celiac and superior mesenteric arteries. The solar plexus includes the paired celiac ganglia, the unpaired superior mesenteric ganglion, and numerous nerves that run from the ganglia in various directions in a manner resembling the sun’s rays (whence the name). The ganglia of the solar plexus consist of nerve cells with many processes. The branches of the preganglionic fibers, which pass without interruption through the ganglia of the neighboring sympathetic trunk, terminate in synapses on the bodies and processes of the nerve cells. In addition to sensory and parasympathetic fibers, the nerves of the solar plexus contain many postganglionic sympathetic fibers, which are processes of the ganglion cells of the solar plexus and which innervate the glands and musculature of the vessels of the diaphragm, gastrointestinal tract, spleen, kidneys, adrenals, and other organs.
