Summary Introduction

To compare: The microscopic anatomy of smooth muscle to skeletal muscle.

Concept introduction: Skeletal muscle fibers that are composed of single muscles are differentiated into three categories based on two criteria, such as the type of contraction generated and primary means used for ATP supply. Smooth muscle cells are fusiform shaped and small with the centrally located nucleus. They are located throughout the human body typically composing about $\text{2}\text{\%}$ of the total body weight.
