1909 edition. Excerpt: ...cranial nerves. There are three principal
plexuses formed in connection with the sympathetic, which minister
to the viscera of the chest and abdomen. These are the cardiac,
solar, and hypogastric plexuses. The great cardiac plexus is
situated opposite tho third dorsal vertebra, at the point whero the
bronchial tubes branch off from the windpipe. It is formed by the
union of the middle and inferior cardiac nerves, which, in turn,
are formed by the convergence and union of fibres from tho cervical
ganglia. The great cardiac plexus also receives fibres from the
first thoracic ganglion, the pneumogastric i Also called the
foramen lacerum postering. 1 A muscle at the posterior part of the
neck and shoulder which elevates the shoulder, depresses it, or
carries it back, according as one or other set of fibres is
contracted. and the hypoglossal nerves--tenth and twelfth pairs
cranial nerves. The fibres passing from the great cardiac plexus,
after being concerned in various complications of plexuses and
ganglions, finally proceed to the heart and the great blood
vessels, and follow the latter throughout tho system in all their
subdivisions and ramifications. From the sixth, seventh, eighth and
ninth, and sometimes the tenth, thoracic gangliai branches start
out, descending inwards and uniting into a single trunk to form
what is called the great splanchnic nervo. It enters the abdomen,
passes behind the stomach, and divides into several branches which
enter the semilunar ganglion. Thence numerous filaments emerge to
form the great solar plexus, which is situated on the vertebral
column, the aorta, and the pillars of the diaphragm. The nerves
issuing from this plexus follow the aorta and all its branches,
supply the liver, spleen, pancreas, kidneys, testes...
