The sympathetic trunk is a fundamental part of the sympathetic nervous system ( stimulates the body’s flight or fight response). The trunk, originating via the Vagus Nerve runs from T1L2 and affects various parts of the body from pupil dilation and sweat glands to the rapid functions of the lungs, heart, stomach and bladder. A feline diagram below best depicts the areas affected from nerves that radiate from the trunk.
As the vagosympathetic trunk affects a multitude of organs, there a many diseases associated within these pathways from seizures (vagus nerve) to hyperthyroidism and atrial arrhythmias to name a few.
