The degree of development and structure of muscles-antagonists moving the fingers and structure of their innervation apparatuses are in a direct dependence on the function which is performed by pectoral limbs of the animals. The flexors of the fingers are developed considerably greater than the extensors and the difference between them is the greater the higher is the phylogenetic position of the animals. The flexors of the fingers are also innervated better than the extensors. During the process of evolution the intramuscular structure of the antagonists perfects and complicates, permitting them to endure equally both dynamic and static loadings. Nervous and muscular tissues of the antagonists develop harmoniously and their quantitative interrelation depends on functional properties of the muscles: dynamic muscles are innervated better than statical ones. The muscles-antagonists of right and left forearms and their innervation apparatuses are developed identically.
