Organic and functional nervous diseases; a text-book of neurology . f of the deep flexors of the flngers, the musclesof the little finger, the interossei, the inner two lumbricales, and theadductors of the thumb. The result of paralysis of the ulnar flexor of the wrist is not verymanifest, as other muscles are capable of doing the work of theflexor carpi ulnaris. A paralysis of the flexor profundus digitorummakes the patient incapable of flexing the first phalanges of the littleand ring fingers, hence there is no opposition to their extreme exten-sion, and part of the deformity of the hand resulting from ulnar nervepalsy (Figs. 98 and 99) is due to this cause. The chief disability, however, produced by ulnar nerve lesions is theparalysis of all the intrinsic muscles of the hand excepting the first and 188 INJUmES OF SPINAL NERVES AND NEVmflS. second lumbricales, which are supplied by the median nerve. As aresult of this paralysis the use of the thumb and fingers is very muchimpaired, the thenar and hypothenar eminences become flat and flabby, Fig. Fig. 97.
