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

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”

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

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

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

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)

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

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)

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

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

Directional Terms
• Used to describe areas divided by
•
•
transverse plane
Superior (cranial or cephalic) means
toward head or upper body
Inferior (caudal) means away from head or
toward lower part of body
– Any body part can be either superior or
inferior, depending upon point of reference
– Example: knee is superior to ankle and inferior
to pelvis

wrist would be proximal and your shoulder
would be distal

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

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

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

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

Standard X-Ray Positions (cont’d)
• Lateral
– X-ray beam passes from one side of patient to
other, and then onto film
– Often used as compliment to PA views, to get
better 3-D perspective

Computerized Tomography
(CT or CAT Scan)
• Produces series of cross-sectional
•
•
“slices” through body
Generates high-resolution images with
more information about 3-D orientation of
structures
Exposes body to much higher levels of
radiation than traditional X-ray

Magnetic Resonance Imaging (MRI)
• Uses magnetic energy to image body
• Produces cross-sectional images
• Images have much better clarity than CT

Magnetic Resonance Imaging (MRI)
(cont’d)
• Cannot be used by all patients
–Patients with certain metallic components in
body (like metallic aneurysm clips or heart
valves) cannot be exposed to magnetic field of
MRI; would make metal components shift in
body
–Patients who are claustrophobic may not be
able to tolerate entering small tunnel of
traditional (closed) MRI; open MRIs are
alternative for these patients

anatomical position facing forward with
arms at side and palms facing forward
Other positions include prone, supine,

Body can be divided into planes, including
transverse and median plane
