Abstract:
:The effect of muscle temperature on the speed of contraction and on the strength of contraction of the cat jaw muscles was studied. Muscles contracted faster when their temperatures were increased. The tetanic and twitch tension decreased significantly as the animal was heated from 30 to 40 degrees C.
