Lab 1 – Introduction Rev. 4 Bio47 - Human Anatomy 1 Name: ____________________________________________ Introduction / Terminology Objectives : 1. Obtain an understanding of anatomy and the subdivisions which comprise the major disciplines in the study of the structure of the human body 2. Obtain an understanding of the generalized body structure 3. Mastery of Anatomical terms : Body Regions, Planes of section, Directional Terms, Body Cavities 4. Understanding of serous membranes and their significance I. Anatomy : Human Anatomy is the scientific discipline concerned with the organization and structure of the human body. The term anatomy originates from its Greek roots meaning literally to “ cut up .” Anatomy was born from the discoveries of these early anatomists. Since their study was limited to observations made available through the dismemberment of unfortunate individuals, their study was confined to only those structures discernable with the naked eye; large, visible, dissectible, physical attributes. Today this aspect of anatomy is described as Macroscopic (large) or Gross Anatomy . As with all other scientific disciplines, the study of anatomy has paralleled technology. Unlike the early anatomists which were limited to structures they could see with the unaided eye, today anatomists go beyond elucidating just macroscopic structures and include the descriptions and understanding of structures visible through the use of technology. Anatomy today includes structures which are discernible through the use of highly advanced microscopic and computerized digital equipment, such as electron microscopes, CT scans (Computerized Tomography), and MRI’s (Magnetic Resonance Imaging). We will begin our understanding of the structure of the human body with the smallest structural unit of life, the cell. This study of cell and cellular function is referred to as Cytology. It will serve the same purpose in our studies as it does in the body; it will form the framework onto which we will build our understanding of Anatomy. Anatomy is more than just observing the physical structure of the body and body parts. The goal of anatomy is to be able to discern the plausible function in the structure. The beauty and the challenge of anatomy is to be able to determine the functional significance for a specific structural design. Beneath every structural design in lies the function. It is through the understanding of anatomy that we will build the foundation for our understanding the function, or the Physiology , of the human body. II. Divisions of Anatomy : Anatomy is a broad field of study consisting of several divisions or sub- disciplines. Each division of anatomy specializes on a specific aspect of the body’s arrangement. These divisions are outlined below : 1. Macroscopic (Gross) Anatomy : Study of structures which can be seen with an unaided eye. a.
