myothermic

The fundamental difficulty in myothermic observations is the smallness of the changes involved and their rapidity.

Archibald V. Hill - Nobel Lecture 1965

The resistance thermometer has not been employed successfully in myothermic observations.

Archibald V. Hill - Nobel Lecture 1965

In 1919 Hill's friend W. Hartree, mathematician and engineer, joined in the myothermic investigations - a cooperation which had rewarding results.

Archibald V. Hill - Biography 1965

We have dealt so far, for several reasons, with the simple case of the isometric contraction: firstly, because it involves us in one less variable, namely, the length of the muscle, and secondly, because myothermic experiments on the isometric contraction are so much simpler and freer from error.

Bürker (who taught him much about the technique of myothermic observations) and Paschen (who introduced the galvanometer to him, which he since used for his investigations).

Archibald V. Hill - Biography 1965

The possibilities already available of myothermic investigation are mainly due to improvements in galvanometers and thermopiles.

Archibald V. Hill - Nobel Lecture 1965

I have attempted recently to use a resistance thermometer for myothermic observations and found it completely impossible, owing to the errors produced by the heat production in the resistance thermometer itself.

Archibald V. Hill - Nobel Lecture 1965

It is possible to make a small light thermopile, suitable for myothermic observations, containing one hundred couples, each providing 50 micro-volts for a difference of temperature of 1°C.

The myothermic method, however, employing small thin muscles subjected only to very light stimulation makes it possible to follow the recovery process under conditions where the rate is quite uninfluenced by any possible lack of oxygen.

Archibald V. Hill - Nobel Lecture 1965

Owing to the heat capacity of the recording instruments and the lag in the conduction of heat and in the galvanometer deflection, the readings actually obtained with myothermic apparatus are considerably smaller than those calculated from the physical data of thermoelectromotive force, number of junctions, and galvanometer sensitivity.
