Where the involvement is ex-tensive the limb fails to grow and remains much shorter than that ofthe opposite side (Fig. 178); the circulation is defective, the limbappearing cyanosed and feeling colder than the normal one. Whereopposing muscles to those paralyzed retain their function various defor-mities may result, due to the unopposed contraction of the normalmuscles. Sensation is not disturbed, as a rule, although in some cases theaffected muscles may be tender to pressure. The sphincters remain is no disturbance of mentality.
