Introduction • This chapter provides you with the major • external map of the human body Future chapters get into more depth for each particular area and begin to provide a detailed map of interior regions Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Introduction (cont’d) • Medical directional terms and body • locations will serve as a foundation upon which to build By the time you finish your journey through this book you will know your own body like “the back of your hand” Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Learning Objectives • • • • • • • List and describe the various body positions Define the body planes and associated directional terms Locate and describe the body cavities and their respective organs List and describe the anatomical divisions of the abdominal region Identify and locate the various body regions Relate the various diagnostic tests to view the body Describe situations in which body position can help or hinder the disease process Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Importance of Mapping • Does the statement “I have pain in my • • stomach” tell you a lot about exact location? Location of pain can be determining factor in diagnosis Questions about type of pain, exact location, and intensity of pain can help determine etiology Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Body Positions • The body can assume many positions and • • therefore can have different orientations To standardize orientation for the study of anatomy, scientists developed the anatomical position In the anatomical position, the person is standing erect, face forward, with feet parallel, arms hanging at sides, and palms facing forward Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Figure 2-1 The anatomical position. Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Other Important Body Positions • Supine position: laying face upward, on • • your back Prone position: laying face downward, on your stomach Fowler’s position: sitting in bed with head of bed elevated 45–60 degrees – This position often used in hospitals – Facilitates breathing and comfort of bedridden patient Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Figure 2-2 Common patient positions. Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Pathology Connection • Body positions relevant to certain clinical • • scenarios Patients with secretions at the base of the lungs may benefit from Trendelenburg position (which helps drain secretions) Patients with cerebral injury or bleeding should avoid Trendelenburg position (because it increases blood flow to brain, increasing intracranial pressure) Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Pathology Connection (cont’d) • Patients to be placed in Trendelenburg • position are at increased risk for aspirating vomitus, and should not eat within 2-4 hours of being placed in position Patients with orthopnea have difficult time breathing if they lie flat; propping them up with pillows assists diaphragm in working against gravity Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Pathology Connection (cont’d) • Changing from upright to supine position can help determine cause of distended neck veins (jugular venous distention) – If patient has distend neck veins due to heart failure, lying down will decrease distention (heart has to work less hard against gravity, causing less “back up” of venous blood) Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Pathology Connection (cont’d) • Dizziness when changing from seated to standing position can indicate orthostatic hypotension – Symptoms develop because heart cannot compensate for extra work against gravity standing requires; result is deficient blood flow to brain Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Body Planes and Directional Terms • Sometimes it is necessary to divide body, • • or even organ or tissue sample, into specific sections to further examine it A plane is an imaginary line drawn through body or organ to separate into specific sections Transverse or horizontal plane: divides body into superior (top) and inferior (bottom) sections, also referred to as cross-sectioning the body Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved.

Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. X-Rays (Radiograph or Roentgenogram) • Produced by passing X-ray radiation through specific area of body onto photographic film – Exposure to X-rays causes photographic film to darken – Radiolucent areas of body allow X-rays to pass through to film easily; produce dark areas on film – Radiopaque areas of body allow fewer X-rays to pass through to film; produce light areas on the film Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. X-Rays (Radiograph or Roentgenogram) (cont’d) • Each component of body has characteristic density (and characteristic appearance on X-ray) – Air: least dense; shows up black on X-ray – Tissue/Fat: density depends on thickness of tissue; thicker the tissue, lighter the appearance on X-ray Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. X-Rays (Radiograph or Roentgenogram) (cont’d) • Each component of body has characteristic density (and characteristic appearance on X-ray) – Water (blood and edema): mid-range density; appearance on X-ray is lighter than air, but not as white as bone/metal – Bone/Metal: highest density; appears white on X-ray Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved. Standard X-Ray Positions • Posteroanterior (PA) – X-ray beam passes from patient’s back to patient’s front and then onto film – Standard view for chest X-ray • Anteroposterior (AP) – X-ray beam passes from patient’s front to patient’s back and then onto film – Often used in portable chest X-rays Anatomy, Physiology, & Disease, Revised First Edition Bruce J. Colbert, Jeff E. Ankney, and Karen T. Lee Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved.
