Such plexuses occur in all gnathostomes, and they reach their highest complexity among mammals and birds in which the cervical plexus supplies many ventral neck muscles, the brachial plexus supplies the pectoral appendage, a lumbosacral plexus supplies the pelvic appendage, and a coccygeal plexus supplies some of the pelvic muscles.[well established][VHOG] UBERON:0001814 EHDAA:3782 brachial plexus An arrangement of nerve fibers, running from the spine where it proceeds through the neck then the axilla and into the arm where it innervates skin and muscle.
