Studies in Denervation: B.--the Circulation in Denervated Digits

“…Lewis and Landis (1929-31) showed by the pilomotor response to local faradism that the operation left intact the post-ganglionic fibres to the pilomotor muscles over the lateral aspect of the shoulder and upper part of the arm. That the negative results obtained elsewhere in the extremity can be interpreted as proving the complete absence of postganglionic fibres in general and to blood vessels in particular is doubtful and Guttmann's (1940) observations on subjects with excision of the middle and superior cervical ganglia indicate that the area described by Lewis and Landis is only the autonomous zone of supply of the upper ganglia. Foerster, who has observed vasoconstriction in the limb produced by stimulation of the middle cervical ganglion (1935), has also shown that C.6 is distributed to the skin as far as the mid-axial line of the limb (1933).…”
