THE CCELIAC OR SOLAR PLEXUS 



1077 



The Phrenic Plexus (plexus phrenicus) (Fig. 785) accompanies the inferior 

 phrenic artery to the Diaphragm, some filaments passing to the suprarenal gland. 

 It arises from the upper part of the semilunar ganglion, and is larger on the right 

 than on the left side. It receives one or two branches from the phrenic nerve. 

 At the point of junction with the phrenic nerve is a small ganglion, the phrenic 

 ganglion (ganglion phrenicum) (Fig. 786), which lies on the under surface of the 

 Diaphragm, near the right suprarenal. Its branches are distributed to the 

 inferior vena cava, suprarenal, and hepatic plexus. There is no phrenic ganglion 

 on the left side.

The Suprarenal Plexus (plexus suprarenalis) (Fig. 785) is formed by branches 

 from the cceliac plexus, from the semilunar ganglion, and from the phrenic and 

 great splanchnic nerves, a ganglion being formed at the point of junction of the. 

 latter nerve. It supplies the suprarenal gland, being chiefly distributed to its 

 medullary portion. The branches of this plexus are remarkable for their large 

 size in comparison with the size of the organ they supply.
