Now in its Fifth Edition, Functional Anatomy and Physiology of Domestic Animals provides a basic understanding of domestic animal anatomy and physiology, taking an interconnected approach to structure and function of the horse, dog, cat, cow, sheep, goat, pig, and chicken.
Offers a readable introduction to basic knowledge in domestic animal anatomy and physiology
Covers equine, canine, feline, bovine, ovine, ruminant, swine, and poultry anatomy and physiology
Considers structure and function in relation to each other for a full understanding of the relationship between the two
Provides pedagogical tools to promote learning, including chapter outlines, study questions, self-evaluation exercises, clinical correlates, key terms, suggested readings, and a robust art program
Includes access to a companion website with video clips, review questions, and the figures from the book in PowerPoint

In general, the study of anatomy refers to the study of the structure of body parts and includes gross anatomy (identification by unaided visual means) and microscopic anatomy (identification by microscopic assistance that usually begins at the cellular level). The study of physiology is a study of the functions of the body, or as sometimes stated, “how the body works,” and includes biophysical and biochemical processes and precludes a knowledge of anatomy. Although anatomy and physiology can be taught as separate entities, overlaps are unavoidable and it follows that greater productivity is obtained by integrating the two disciplines.
The study of anatomy and physiology is assisted by prerequisite courses, which include chemistry, physics, biology, and quantitative skills in mathematics. With this in mind, we will rely not only on your previous preparation, but also on the desire to advance your knowledge with application to animal anatomy and physiology. This chapter provides basics of structure and function that should be helpful to you as you study the chapters that follow.
THE CELL, ITS STRUCTURE AND FUNCTIONS
What separates the cell cytoplasm from interstitial fluid?
What are organelles?
Define the nuclear membrane.
What does chromatin become in dividing cells?
Differentiate between granular and agranular endoplasmic reticula and their associated functions.
Are the vesicular structures of the endoplasmic reticulum separate or interconnected?
What is the function of the Golgi apparatus?
What organelle is the site of the citric acid cycle?
What is the principal substance of lysosomes?
What cellular function are the centrioles associated with? What is their location within the cell known as?
The number of cells in an animal is in the trillions and for the human has been estimated to be about 100 trillion. Each of these cells had their start beginning with fertilization of an oocyte. The appearance of cells varies with the organ of which they are a part and will be shown and described when encountered. Cells are highly organized chemical systems and share many features that are shown schematically in Figure 1-1. The basic components of a cell are the plasma membrane(cell membrane) that bounds the cell and gives it limits; the cytoplasm, which is the homogenous ground substance that forms the background in which the formed elements are suspended; and the nucleus. The nucleus is separated from the cytoplasm by a nuclear membrane and the cytoplasm is separated from the surrounding fluids (interstitial fluid) by a cell membrane. The cell membrane is usually pliable and is composed of phospholipids and proteins. The phospholipid molecules occur in two layers. The protein molecules may be associated with either the outer or inner layer and may penetrate completely or incompletely (see Chapter 2).

Because of cell specialization, no cell can be called typical. The cytoplasm is the location of diverse metabolic activities and is filled with both minute and large dispersed particles and organelles.
The Organelles
The organelles are highly organized physical structures represented in Figure 1-1 and, in addition to the cell membrane, consist of the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes, and centrioles. These structures assist the cytoplasm with its metabolic activities by receiving materials into the cell, synthesizing new substances, generating energy, packaging materials for transport to other parts of the cell or to the circulati...
