This is regularly to befound and as a rule is easily excitable. Er^s (supra-clavicular) poi7it—a point in the cervico-brachial plexus—generally a little more than a thumbsbreadth above the upper clavicular border and a littleto the side of the sterno-cleido-mastoid. It naturallychanges its position considerably, according to the formof the upper clavicular hollow. From this point out weget contraction of the deltoid, biceps, brachialis internus,and brachio-radialis muscles; that is, a jerking abductionof the arm from the thorax and forceful bending of the m. frontal in. coiTug. siipereupper facialbranch m. orbic. ocuiimm. nasales mm. zygomat. \. n. bypoglossus m. temporal. n. facialis (trunk) m. splenius. m. sternocleidom. n. accessorlus. m. levator ,j m.
