"A single muscle rarely or never contracts alone, but always in harmony with a number of other muscles. Even the simplest movement we can make requres the combined action of several muscles to carry it out. If the movement is at all difficult, such as playing on the piano or riding on the bicycle, the different muscles must contract in a certain order and with a certain strength and rapidity." — Blaisedell, 1904

This illustration shows a diagram of nervous and cross-striate muscular tissue, showing the mode of connection between nerve fibres and muscle fibres. A, nerve cell (g) connected with muscle fibre (mf.) by nerve fibre (n.f.). The muscle fibre (m.f.) is composed of numerous fibrils (f) which are made up lengthwise of alternating discs of ligter and darker substance. These fibrils are shown more highly magnified in B and C. In B the fibril is uncontracted; in C it is contracted. D, nerve fibre more highly magnified showing a, axis; m, medullary sheath; and s, Schwann's sheath; ax., axon; d, dendron; n, node; n.m., nerve-muscle plate.
