Anatomy and physiology is a challenging course, and this laboratory manual is written to help students meet that challenge. It is written for students interested in allied health fields, such as nursing; physical, respiratory, cardiovascular, or occupational therapy; radiology; and den- tal hygiene. This manual may be used with any two-semester anatomy and physiology textbook.
The design of this laboratory manual is based on the au- thors’ experience as anatomy and physiology instructors and uses three learning styles: visual, auditory, and kinesthetic. When students label diagrams, they focus on the structure rather than just the dot at the end of a line. Writing out the structure’s name and pronouncing it reinforces learning. Also, having students become subjects of laboratory exer- cises personalizes the learning process. Animal dissections give students an opportunity to physically manipulate struc- tures, comparing location and texture, and to observe how structures are supported, protected, and attached by connec- tive tissue.
Special features incorporated in this laboratory manual include:
• This lab manual can be used for online anatomy and physi- ology classes. New lab activities have been added that can be performed by students at home or used in the labora- tory. Online students can also use the Real Anatomy Virtual Dissection program and PowerPhys physiology activities to enhance their learning.
• Just enough text is provided to introduce concepts in each section and to set up and support the laboratory section. The exercises are written so students do not need their textbooks to complete the laboratory activities.
• New material is divided into small segments, starting with simple diagrams, illustrating the basic concepts and build- ing up to more complex diagrams. Subsequent activities add to the students’ knowledge in a stepwise fashion. This is especially noticed in the skeletal and muscular exercises.
• Each exercise contains a list of objectives, materials needed for the exercise, and easily identifiable laboratory activity sections.
• Unlabeled four-color drawings, photographs, and photomi- crographs are included for students to label either at home or in the laboratory. Students first write out the name of the structure to help learn it. Then the completed diagrams will be used to identify structures on models.
• Word derivatives for bolded terms are given in the text. • Phonetic pronunciation is included as new words are intro-
• Physiology experiments use students as subjects and can be completed with either simple, inexpensive equipment and materials or more complex lab setups.
• Experimental report sections after physiology experiments where students are asked to make predictions, collect and analyze data, and write simple lab reports.
• Discussion Questions are within the activities to make the students think about the material presented.
• An Answer Key is provided at the end of the laboratory manual for the activities in each exercise. Students receive immediate feedback, and they are not dependent on the in- structor for the correct answers.
• “Reviewing Your Knowledge” and “Using Your Knowl- edge” sections follow the activities at the end of each ex- ercise. “Reviewing Your Knowledge” provides a thorough review of the material in the exercise, whereas “Using Your Knowledge” requires students to apply information learned. Either or both of these sections may be handed in to the instructors for a grade, because neither section has answers in the back of the laboratory manual. Answers to these two sections are provided on the Instructor Companion site.
New Features to the Fifth Edition • Exercises are now organized into Before Going to Lab and
Lab Activities. Before Going to Lab sections are to be com- pleted at home or outside of class.
• Completely revised Exercise 15: Surface Anatomy and Exercise 26: Blood Components and Blood Tests.
• Suggested Real Anatomy activities are included throughout the lab manual.
• PowerPhys 3.0 is now tablet enabled and includes three new modules.
• New Biopac Laboratory Guide Experiments are available online for several Exercises. Activities include: ~ Recruitment and Fatigue ~ Isometric and Isotonic Contractions ~ Effect of Physical and Mental Distractions on Patellar
Reflex (Knee Jerk) Response ~ The Effect of Mental and Sensory Stimulations on Brain
Wave Patterns ~ Observing ANS Responses to Lying ~ Observing ANS Responses Following Meditation ~ Effect of Body Position and Exercise on ECG ~ Heart Sounds and Events of the Cardiac Cycle ~ Effect of Body Position on Resting Blood Pressure ~ Effect of Exercise on Blood Pressure ~ Effect of Exercise on Lung Volumes and Capacities ~ Comparison of Predicted and Measured FVC and FEV1
vi P R E F A C E
PowerPhys 3.0 is Tablet Enabled and Fully Integrated with The New Edition
Each Lab Manual contains online access to Power- Phys 3.0 for students. PowerPhys 3.0 is physiologi- cal simulation software for the A & P laboratory that allows students to explore physiology principles through 14 self-contained activities. Each activity follows the scientific method containing objectives with illustrated and animated review material, pre- lab quizzes, pre-lab reports (including predictions and variables), data collection and analysis, and a full lab report with discussion and application questions. Experiments contain real data that is randomly gener- ated, allowing users to experiment multiple times, but still arrive at the same conclusions. These activities focus on core physiological concepts and reinforce techniques experienced in the laboratory. www.wiley. com/go/powerphys • Three New Activities: Hematocrit and Hemoglobin Concentration and
Effect of Dietary Fiber on Transit Time and Bile • Now available on mobile devices
Dissection Manuals • Depending on your needs, a Cat Dissection Man-
ual or Fetal Pig Dissection Manual is available to accompany the main Lab Manual. Both dissection manuals contain dissection activities for use in the lab accompanied by full color photos and figures.
• All cat and pig photographs have been updated in the new editions.
• New cat and pig dissection videos accompany this edition, available in WileyPLUS. Dissections per- formed by Shawn Miller and photographs taken by Mark Nielsen of the University of Utah.
Resources That Power Success

Anatomical terms describe body positions, body regions, specific body areas, and land-marks. Most of these words are derived from Latin or Greek and are often part of the names of muscles, bones, nerves, and blood vessels. Learning these terms at this time will help you throughout the course.
A. Anatomical Terms
The anatomical position is the reference position anato- mists and people in medical fi elds use to describe the loca- tion of body parts or regions. In the anatomical position, the body is erect (vertical) and facing forward; the arms are straight and at the sides of the body with the palms facing forward; the legs are straight with the feet facing forward and fl at (Figure 1.1). In the supine position, the body is horizontal and lying on the back. In the prone position, the body is horizontal and lying on the stomach. Body regions refer to specifi c areas of the body. There are common misperceptions about the boundaries of a few body regions. Two common misconceptions are that the arm is the area between the shoulder and wrist and that the leg includes the
thigh. Actually, the arm is located between the shoulder and elbow, and the forearm is located from the elbow to wrist. The thigh is located between the groin and knee, and the leg is located between the knee and ankle. The chest is the area of the trunk between the neck and diaphragm and contains the heart and lungs. The abdomen is the area of the trunk between the diaphragm and hip bones and contains the digestive organs. The pelvis is the area of the trunk below the hip bones and contains internal reproductive organs and the urinary bladder. The groin is the area on the anterior (front) surface marked by a crease where the lower limb attaches to the pelvis. Many anatomical terms have one or more word roots with a prefi x and/or a suffi x added. For example, in the word antecubital, ante- is a prefi x meaning before or in front of, the word root cubit- means elbow, -al is a suffi x meaning pertaining to. Table 1.1 contains anatomical terms with four different suffi xes, all of which mean pertaining to. These suffi xes are -al, -ic, -ar, and -ary. When suffi xes like these are added to word roots they form adjectives, whereas nouns have different endings such as -um, -us, -is, and -a. For example, stern- is a word root meaning chest; sternum is the noun and sternal is the adjective. Anatomi- cal terms and their defi nitions are found in Table 1.1. Word roots and their defi nitions are found in Appendix A, as well as nouns and adjectives formed from the word roots.
