Kyle Black M.S. C.E.S.

2. Objectives ◊ Define Anatomy and Physiology
◊List and discuss in order of increasing complexity the levels of the human body
◊Define the term anatomical position
◊List and define the principle directional terms and sections (planes) used in
describing the body and the relationship of body parts to one another
◊List the nine abdominiopelvic regions and the abdominopelvic quadrants
◊List the major cavities of the body and the subdivisions of each.
◊Discuss and contrast the axial and the appendicular subdivisions of the body.
Identify a number of specific anatomical regions in each area.
◊Explain the meaning of the term Homeostasis.

3. The study of the structure of an organism
◊ Define Anatomy and Physiology
Anatomy
The study of the structure of an organism
and the relationships of its parts. Derived
from two Greek words that mean
“a cutting up”
Physiology
The study of the functions of living
organisms and their parts

4. ~These three can only be seen with
◊List and discuss in order of
increasing complexity the levels
of the human body
~Know these in order~
Atoms – smallest,
Molecule – chem. level of organization
Cells – smallest living things, not simple
~These three can only be seen with
a microscope~
Tissue – an organization of many
similar cells that act together to
perform a common function
Organ - Larger more complex than
tissues, a group of several different
kinds of tissues arranged so that they
can act as a unit of perform a special
function.

5. ◊Define the term anatomical position
The body is in an erect or standing
posture with the arms at the side and
palms turned forward. The head and
feet also point forward.
Why do you need to know this?
positioning patients
know where body parts are to follow
directions
Anatomical directions
Superior vs. Inferior
Anterior vs. posterior
Medial vs. lateral
Proximal vs. distal
Superficial vs. deep

6. ◊List and define the principle
directional terms and sections
(planes) used in describing the body
and the relationship of body parts
to one another
Sagittal – running front to back
dividing the body into left and
right sides
Frontal (coronal) – running left to
right dividing the body into
anterior (front) and
posterior (back) portions
Transverse – horizontal plane or
crosswise plane dividing the body
into upper and lower portions
