In the phylogenetic changes undergone by the muscles under consideration, the innervation may have changed in some instances, although this is less likely to occur than changes in the attachment or function of the muscles.
There is no problem, however, in determining to which of these two branches he is referring when he is describing the innervation of a particular muscle, since one supplies only muscles of the shank and the other only intrinsic foot muscles.
II to be innervated by branch III (Ic of Gadow); thus the innervation of this muscle corresponds to that found in Rhea by Gadow.
If a change in innervationhas occurred, it would be more likely to be a change from one dorsal nerve to the other or from one ventral nerve to the other rather than from a dorsal nerve to a ventral one or vice versa.
The innervation was not given for the intrinsic foot musculature.
Struthio by twigs of the femoral nerve in addition to its typical innervation from branch II of the sciatic nerve; this agrees with Gadow's findings in the same genus.
The important differences in innervation between these studies and the present one are discussed below.
Gadow, on the other hand, reports a typical innervation for this muscle in Rhea.
Consequently more work needs to be done before a complete understanding can be obtained of the innervation of the leg muscles of birds.
Howell (1938) listed the innervationof the hip and thigh muscles in the chicken; he did not include the lumbosacral plexus.
Many differences in the innervation of specific muscles are reported in the literature, even in the same species (by different workers).
This strong, yet apparently alien, motor innervation corresponds in fact as closely as possible to our idea of an invasion--an invasion no longer of the room only in which the percipient is sitting, but of his own body and his own powers.
Fleck reports the case of a Dutchman who, during the last two years, by some peculiar innervation of the intestine, had only five or six bowel movements a year.

In many such cases it appeared that the suspects were harmless spectators who were simply more obvious in their innervation of the muscles involved in the assault they were eagerly witnessing.
The second important element is theinnervation of the muscles in consequence of movement merely seen.
The awakening of the muscular sense is frequently obvious whenever movement is thought of, and we may then perceive how, in the explanation or description of a movement, the innervation which follows the image in question, occurs.
