Question
Chapter 6, Problem 16SAE
Summary Introduction
To review:
The difference in the isotonic and isometric contractions.
Introduction:
The muscles contract as a result of sliding of the myosin filaments over the actin filaments. Thus, shortening of the muscle fibers brings about the contraction of the muscles. These muscles not always shorten during contraction.
