Not illustrated. 1919 edition. Excerpt: … action by the visceromotor reflex as detailed above; but particularly those receiving innervation from the anterior roots of the IIIrd and IVth segments, thus: sternucleidomastoideus, scalenus anticus and medius, trapezius and rhomboidei. The muscles affected are shown in Fig. 35, page 163. Thus the viscerotrophic is much wider in the extent of tissue involved than either the visceromotor or viscerosensory reflexes. There is a condition present in most people which proves to be very confusing in determining the trophic reflex changes which arise from the lung in the soft tissues immediately below the clavicle on the side of the arm that is used more. As previously mentioned, the shoulder on the side which is used more, is lower than the other because of a lengthening of the muscles which support it. As the acromion drops, the end of the pectoralis which is attached to the arm is lowered. This lowers the entire pectoral muscle mass and accentuates the subclavicular groove. This must not be taken for the reflex degeneration of subcutaneous tissue and muscle which results from inflammation of pulmonary tissue. Careful examination will reveal the difference and show the lessening of the subcutaneous tissue as well as the changes in its texture which denote atrophy. While innervation follows the body segmentation for the most part, yet it is not exact, and extension beyond the usual limits of a given nerve may now and then be found. Roughly speaking, however, it may be said that a viscerotrophic reflex affecting the skin and subcutaneous tissue above the second rib anteriorly and the spine of the scapula posteriorly and extending up into the neck, is of pulmonary origin; while that extending from these areas downward to the lower…
