gravity of the affection are directly influenced by the proximity of the
injury to lymph plexuses. For instance, injuries causing an infectious
inflammatory involvement of the adductors of the thigh may result in a
generalization of the infection by way of the inguinal lymph glands.

Large open wounds that extend deep into muscles, render inactive such
structures, and even where division is not complete, the pain occasioned
causes the subject to favor the part in every way possible. Contraction
of muscular fibers of such parts increases pain and because of this fact
groups of muscles are at times disabled because of injury done to one
muscle. Instances of this kind are frequently seen where shoulder
injuries, which affect but one muscle, exist; yet because of such injury
a marked swinging-leg lameness is present.

Tendons, because of their inelasticity, are subjected to injuries
peculiar to themselves. In addition to being affected as are muscles,
wounds of many kinds are found to affect tendons--contusions,
interference wounds, penetrant wounds, incised wounds and lacerations.

However, the commoner form of injury done tendons, is strain or sprain.
Because of the sudden tensile strain brought to bear upon tendons in the
shocks of concussion, as well as in propulsion of the body, there
frequently occurs a rupture of fibers and this we know as sprain.

Sprains may be considered as fibrillary fractures of soft structures and
since this form of injury is subsurface, and limited to fractional
portions of tendons, the inflammation occasioned usually remains an
aseptic one. Reaction to this form of injury is characterized by
inflammation, the course of which is erratic and variable. In chronic
inflammation of tendons, where animals are continued in service, the
