1884 Science 15 Feb. 210/2 Wedenskii states that he has been able to demonstrate the presence of the negative variation of the natural nerve current in a stimulated nerve by means of the telephone in a way similar to that described by Bernstein and Schönlein for the muscle. The quality of the ‘nerve-tone’ does not differ from that of the telephonic muscle-tone.

1999 Canad. Jrnl. Cardiol. 15 323 The isolated dog heart was used to determine the origin of the first heart sound, which was characterized as a muscle tone.

2. Physiology. The degree of tension in a resting muscle. Also gen.: muscular development.

1897 Science 15 Oct. 579/2 Professor Witmer..discussed the differences in muscle tone, the rôle of the mental factor in physical processes, the sexual and racial differences in quickness of movement, etc.

1917 W. A. Evans How to keep Well xxxiii. 594 A man with a heart murmur must be extra careful to keep up his general muscle tone.

1930 Lancet 19 July 127/2 The operation of ramisection, or division of the sympathetic rami to the limbs, was devised by J. I. Hunter and N. D. Royle in the course of some experimental observations upon muscle tone in animals.

1967 Brain 90 278 Lennox..first drew attention to the association of myoclonus and paroxysmal loss of muscle tone in petit mal.
