Anatomy and Physiology

Introduction

Anatomy is related to the structures connected with the body of human. Physiology is the science of functions, performs by each structure. The body of human is normally considered as a typical machine (Koziol et.al, 2013). It is necessary for a machine to work, it is necessary to have all parts in working condition. If all parts of the machine do not work according to their function, the patient is described as encompass some kind of infection or disease. The muscle system is an important part of human body.

The movement of human body depends upon the muscular system. Sacromere is the most important to part of muscle cells. This element is distinctive in muscle tissue is observed on slides of microscope because of striated character of both cardiac and skeletal muscle. Coupled to muscle contraction is a process of conversion, in which electrical stimulus is transformed to some kind of mechanical reaction. It is related to the muscles of body.

Muscular System 

Muscular system of human body is responsible for the movement of human organs. Without the presence of muscles the human organs cannot move from one position to another. The half's of a person's body weight is comprises of 700 named muscles attached with skeletal system and bones. All of these 700 hindered muscles is separate organ constructed of blood vessels, nerves and skeletal muscle tissue (McLeod et.al, 2013). The tissue of muscle is also present in inner parts of digestive organs, blood vessels, and heart.

The functions of muscle tissues are movement of parts of body with the help of skeletal levers, body posture stabilizing, organ volume regulation, thermogenesisn (production of heat), and internal organ protection. It is a number of characteristics elasticity, excitability, extensibility, and contractility.

During the contraction of muscle, the myosin ...
