A manual of diseases of the nervous system . median and ulnar nerves. Injuries to the neck sometimes cause a partial paralysis of the armof peculiar distribution, the special characters and significance ofwhich were first made known by Erb.* A similar paralysis maycome on apart from injury. The muscles affected are the ,often the supra-spinatus and infia-spinatus, the biceps and brachialisanticus, and the supinators. Erb found that there is one spot betweenthe scaleni, corresponding to the sixth cervical nerve, at which electricalstimulation puts all these muscles in action. Hoedemaker, who hasdescribed two cases of this palsy, finds the motor point in a line drawnfrom the sterno-clavicular articulation to the seventh cervical spine,15 centimetres from the edge of the trapezius. The palsy is appa-rently dependent on disease of the roots of the fifth and sixth cervicalnerves, and the fifth, it will be remembered, receives a twig fromthie Besides injuries, this group of palsies may result fromFig. 55.

There was anaesthesia of all parts suppliedby the biachial and cervical plexus. The arm was adducted, the elbow flexed, thehand in the posture shown, flexion of first, extension of second, strong flexionof last phalanges, the first phalanx of the thumb over-extended, the second extreme, and an attempt to overcome it caused great pain. Therewas also some contracture of the toot (equino-valgns). * Heidelberg Society, 1874, Ziemssens Handbucli, 1874, Bd. xii, pt. 2, p. 50J ;see also Bendiardt, Zeitsch. f. kl.
