Abstract
Astbury and Dickinson1 have shown that isolated strips of myosin from unstriated muscle show thermal contraction below 40° C. It is interesting to note that living muscle also begins to show increased tone at this temperature2, 3. The effect of alkalis is to increase the contraction of myosin ; in actual muscle, tone is increased in alkaline solutions4-7.
