When you’re answering practice questions, pay special attention to the ones you get wrong. Write reflections about why you answered incorrectly and what you need to remember about the right answer. Gain better knowledge through mnemonics If you keep thinking “It’s all Greek to me,” congratulations on your insight! The truth of the matter is that most of it actually is Greek. So dust off your foreign language learning skills and begin with the basic vocabulary of medical terminology. Connect with concepts Additionally, the abdomen is divided into quadrants and regions. The mid-sagittal plane and a transverse plane intersect at an imaginary axis passing through the body at the navel (belly button). This axis divides the abdomen into quadrants (four sections). Putting an imaginary cross on the abdomen creates the right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadrant. Physicians take note of these areas when a patient describes symptoms of abdominal pain. Thoracic cavity: The chest; contains the trachea, bronchi, lungs, esophagus, heart and great blood vessels, thymus gland, lymph nodes, and nerve,. as well as the following smaller cavities: Studying anatomy and physiology involves remembering lists of terms, functions, and processes. You can take just the first letter or two of each word from a list to create an acronym. Occasionally, you can go one step beyond the acronym to a clever little thing called a mnemonic device.

Medical and crime shows have made body cavities all too familiar, and anatomically speaking, these spaces are very important, providing housing and protection for vital organs. The following list identifies the cavities of the human body. This is a simple idea that far too few students practice regularly. Don’t stop at underlining and highlighting important material in your textbooks and study guides: Write it down. Or type it up. Whatever you do, don’t just regurgitate it exactly as presented in the material you’re studying. In the 1970s, computer technology took off, taking medical imaging technology with it. Digital imaging techniques began to be applied to convert multiple flat-slice images into one three-dimensional image. The first technology of this sort was called computed axial tomography (commonly called a CAT or CT scan), in which multiple X-ray images are combined into cross-sectional pictures of structures inside the body. These detailed and extensive images were unlike anything that had been available to anatomists before. CT technology is still an active area of development. Major technology manufacturers maintain robust product lines of CT instruments and accoutrements for use in clinics and clinical research.

Latin and Greek roots

Scientifically speaking, human biology isn’t more or less complex, specialized, or cosmically significant than the biology of any other species, and all are interdependent. Every species of animal, plant, and fungus on the planet has both anatomy and physiology. So does each species of protist (one-celled creatures, like amoebae and the plasmodia that cause malaria). At the cellular level (see Chapter 3), all these groups are astoundingly similar. At the levels of tissues, organs, and organ systems (the provenance of anatomy and physiology), plants are very different from animals, and both plants and animals are equally dissimilar to fungi. Anatomy & Physiology For Dummies combines anatomical terminology and function so you'll learn not only names and terms but also gain an understanding of how the human body works. Whether you're a student, an aspiring medical, healthcare or fitness professional, or just someone who's curious about the human body and how it works, this book offers you a fun, easy way to get a handle on the basics of anatomy and physiology.

Not feeling terribly clever at the moment you need a useful mnemonic? Surf on over to MedicalMnemonics, which touts itself as the world’s database of these useful tools. Discover your learning styletip.eps Every time you come across an anatomical or physiological term that’s new to you, pull it apart to see whether any of its fragments are familiar. Using this knowledge, go as far as you can in guessing the meaning of the whole term. After studying Table 1-1 and the other vocabulary lists in this chapter, you should be able to make some pretty good guesses. Looking at the Body from the Proper Perspective
