homology notes

To reach the muscles, dermatomes, and other structures of the limbs, some of the neurons in the spinal nerves come together in the plexus at the base of the limb. 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]
