Summary Introduction

Introduction:

The muscular system consists of three types of muscle- cardiac muscle, smooth muscle and skeletal muscle. Cardiac and smooth muscle are involuntary muscle whereas skeletal muscle is voluntary muscle fiber. The smooth muscle is an involuntary muscle that found in the wall of hollow organs such as stomach, bladder, blood vessels and eyes. The skeletal muscles are voluntary muscle fiber activated by the central nervous system which attached to the skeleton by tendons.
