The similarities and differences between skeletal and smooth muscles on the basis of their cellular anatomy. Introduction: There are three different types of muscle cells found in the body namely smooth muscle cells, cardiac muscle cells, and skeletal muscle cells. The skeletal muscles are under the voluntary control of the body and smooth muscles and cardiac muscles are under the involuntary control of the body.

Summary Introduction

To determine: The similarities and differences between skeletal and smooth muscles on the basis of their neural and chemical control of contraction.

Introduction: The skeletal muscles are under the voluntary control of the body and smooth muscles and cardiac muscles are under the involuntary control of the body. The skeletal muscles are responsible for the locomotion and providing shape to the body. The smooth muscle cells line the internal organs such as esophagus bronchi, trachea, stomach as well as glands.
