2. The lowermost ganglion, winch is the least, and placed
on the last cervical vertebra. A branch goes oft' from it,
and surrounds the subclavian artery and several others, which
unite with other branches from the par vagum, and form the
cardiac plexus.
The trunk of the great intercostal then descends behind
the subclavian artery, by the fides of the transverse processes
of the dorsal vertebral, through the cavity of the chest, re-
ceiving two branches from each of the dorsal nerves coming
from the spinal marrow, as it passes along, and forming as
many small ganglions. It then quils the side of the vertebra?,
accompanies the aorla, and having reached the sacrum, it
produces several ganglions, with the spinal branches coming
from this part; and, lastly, the great intercostal is reflected
inwards, about the os coccygis, ace I joins its fellow of the op-
posite side. Having thus described the course of this nerve,
so justly termed the great sympathetic, it still remains to enu-
merate the several abdominal plexuses which arise from it,—
for the viscera of the abdomen are all supplied from the g;eai
intercostal.
The fifth dorsal ganglion of the intercostal sends off a nerre
into the thorax ; the third dorsal ganglion also sends off a
nerve ; a nerve proceeds from the seventh dorsal ganglion ;
oue also goes from the eighth ganglion ; and another nerve is
given oft" from the ninth and tenth, or sometimes from the
eleventh dorsal ganglion. These five branches, given off by
the dorsal gang Ha, descend in the thorax, in the course of the
vertebrae, and pass through the diaphragm into the abdomen,
where they all unite into one trunk on each side : and this
nerve is called the splanchnic, or little, or anterior intercostal.
The splanchnic intercostal nerve proceeds a very little way
from the diaphragm, before it produces a large ganglion on
