Abstract

Although all vertebrate skeletal twitch fibres share the same basic structure and operate by the same contractile mechanism, they are called upon to perform a host of different functions ranging from slow speed locomotion to high speed sound production. There are a number of important qualitative modifications (protein isoforms with different kinetic rates) as well as quantitative modifications (different densities of important structures) which permit this wide range of activities and form the comparative aspects of muscle physiology.
