Nervous and mental diseases . Fig. 142.—Deformity of foot afterlumbar poliomyelitis acuta. Fig. 143.—Deformity of upper extremity after poliomyelitis anterior acuta. The reflexes are lessened or abolished in proportion to the implicationof the cornual cells making up a part of their arc. Bones which havenot attained their full groT\i:h are frequently retarded or entirely failto develop if their trophic centers are implicated. The seriously atrophied muscles become contracting fibrous bands,and, since they offer neither assistance nor opposition to the synergic andajitergic muscles, distortions soon develop, with joint-changes and some-times subluxations. Joints which depend upon muscular support, asthe shoulder, may allow of so much deformity by the relaxation of themuscles which have lost their tonicity that the articular surfaces Tvidelyseparate. The slin is inactive, often cold, and sometimes dry and scaly,but the atrophic conditions so usual in neuritis are practically absentand bed-sores are al
