As a matter of fact, lesions of the lumbar and sacralregions seem more frequent, and in all cases moreoften accompanied by nervous lesions than woundsof the anterior and internal surface of the thigh. ANATOMY The lumbar plexus is formed by the collection of anastomoticloops given off by the anterior branches of the first three lumbarnerves and a part of the fourth. The rest of the latter unites with the fifth, takes the name ofthe lumbosacral cord, and joins the sacral roots-stock-foto

The mode in which the plexus is arranged varies in different subjects.^ It differs from the brachial plexus in not forming an intricate interlacement, but the several nerves of distribution arise from one or more of the spinal nerves in the following manner: The first lumbar nerve receives a branch from the last tho- racic, gives off a larger, upper branch, which sub- divides into the iliohypo- gastric and ilioinguinal nerves; and a smaller lower branch which unites with a branch of the second lumbar, to form —--i-—:=S-^-stock-foto
