Chapter 41, Problem 2FIB
Summary Introduction
Introduction: Muscle is defined as the soft tissue found in animals and humans. It is composed of actin and myosin protein filaments that slide on one another and cause contraction of the muscle. It helps to produce force and motion. There are three types of muscles such as striated muscle, non-striated muscle, and cardiac muscle.
