Phrenic (n. phrenicus),Communicantes hypoglossi, The phrenic nerve,, or internal respiratory of Bell, is de-rived from the third and fourth cervical nerves, with a branchfrom the fifth. It descends into the chest between the sub-clavian artery and vein, between the pericardium and thepleura, to the diaphragm, to Avhich it is distributed (rami THE NERVOUS SYSTEM. 335.

The beachial plexus (plexus brachialis) is formed bythe anterior branches of the four lower cervical and the hrstupper dorsal nerves—the fifth, sixth and seventh forming onecord, and the eighth cervical and first dorsal another the line of the clavicle (pars infracldvicularis) boththese trunks divide, the adjacent cords of the two upper unitingto form the posterior (fasciculus posterior), and the remainingcords forming the outer (fasciculus lateralis) and inner (fascic-ulus medius) cords respectively, receiving their names fromtheir relative position to the subclavian artery.
