Transcript the language of anatomy

THE LANGUAGE OF ANATOMY
1. Visible describe or demonstrate anatomical position
2. Use proper anatomical terminology to describe body
directions, surfaces, and body planes.
3. Locate the major body cavities, list the chief organs in each
cavity
ANATOMICAL
POSITION
•
•
•
•
•
•
An initial reference point
The body is erect
Feet parallel
Arms hanging at sides
Palms facing forward
Uncomfortable
Directional Terms
 Allow medical personnel and anatomist to explain
exactly where one body structure is in relation to
another.
 Describe the location of the ears in relation to the nose
 The ears are to the right and left of the nose
 The ears are lateral to the nose
Directional Terms
Superior/ Inferior
Term
Definition
Example
Superior
(cranial or
cephalad)
Toward the
head end or
upper part of
the body;
above
The forehead
is superior to
the nose
Inferior
(caudal)
Away from the The naval is
head end or
inferior to the
toward the
breastbone
lower part of a
structure of
the body:
below
Directional Terms
Ventral (anterior)/
Dorsal (posterior)
Term
Definition
Example
Ventral
(anterior)
Toward or at
the front of the
body; in front
of
The breastbone
(sternum) is
anterior to the
spine
Dorsal
(posterior)
Toward or at
the backside of
the body;
behind
The heart is
posterior to
the breast
bone
Directional Terms
Medial/ Lateral
Term
Definition
Example
Medial
Toward or at
The heart is
the midline of
medial to the
the body; on
arm
the inner side of
Lateral
Away from the
midline of the
body; on the
outer side of
The arms are
lateral to the
chest
Intermediate
Between a
more medial
and a more
lateral structure
The collarbone
is intermediate
between the
breastbone and
the shoulder
Directional Terms
Proximal/ Distal
Term
Definition
Example
Proximal
Close to the origin
of the body part or
the point of
attachment of a
limb to the body
trunk
The elbow is
proximal to the
wrist (meaning
that the elbow is
closer to the
shoulder or
attachment point
of the arm than
the wrist)
Distal
Farther from the
The knee is distal
origin of a body
to the thigh
part or the point of
attachment of a
limb to the body
trunk
Directional Terms
Superficial (external)/
Deep (internal)
Term
Definition
Example
Superficial
(external)
Toward or at
the body
surface
The skin is
superficial to
the skeleton
Deep
(internal)
Away from the
body surface;
more internal
The lungs are
deep to the rib
cage

BODY PLANES
AND SECTIONS
• A plane is an imaginary line on the body.
• Sections
•
•
•
•
Sagittal – a cut a long the lengthwise or longitudinal, dividing the body into right and left parts (parasagittal)
Median, or Midsagittal – a cut down the median of the body that spits the body into equal right and left halves
Frontal/ Coronal – a cut along a lengthwise plane that divides the body or organ into anterior or posterior parts
Transverse / Cross– a cut along a horizontal plane, dividing the body into superior and inferior parts
