Anesthesia and intensive care are one of the most important and complex fields of medical sciences and requires spending attention, time, obtaining sufficient information and experience to be able to evaluate patients accurately and provide them with conditions for anesthesia as appropriate as possible in surgery. Also, the science of anesthesia is not limited to the operating room and covers a wide range. The use of scientific techniques in Miller's book is a fluent and eloquent translation of the art that is engraved in this book and its contents are written using the latest scientific texts in the field of anesthesiology, which facilitates the analysis of the contents.

Anatomy (Greek anatomē, 'dissection') is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology, and also in the study of cells.

The complexities of today's organizations make them somewhat difficult to describe. Increasing environmental turmoil has created an atmosphere of change and uncertainty, calling for new capabilities and a new plan. At present, in order to take advantage of the changes in the dynamic environment of the world, management has stepped into the arena of life with all its might and has sought new and new ways to respond to environmental and non-environmental challenges. One of the major changes that has taken shape in management is the change in attitude towards the organization. Until a few decades ago, it was thought that organizations were rational tools to create coordination and control of people in achieving goals that have vertical levels of sections, parts and units based on power relations, but our managers today pay attention to human issues and progress in the shadow of satisfaction. Employees and customers express that they all represent a great movement in the direction of establishing quality culture in organizations. Establishing your quality culture starts from consciously choosing an appropriate management philosophy with the conditions of the organization.

The dorsal region extends from the skull to the end of the tailbone (Coccyx) and includes the back of the head, the back of the neck, the back of the chest, the back of the abdomen, and the upper buttocks. The back area is important because of its low back pain and spine. When examining the superficial anatomy of the back, the hands should hang loosely along the torso and the shoes should be removed.
