Human Body
Objectives
At the end of this unit you should be able to:
– name the cavities of the body and their organs
– locate and identify the anatomical and clinical
divisions of the abdomen
– locate and name the anatomical divisions of the
back
– pronounce and define terms used to describe the
body positions, directions, and planes
– use the new words to understand medical terms

Body Planes
• Sagittal Plane
– divides the body into
right and left sides
• Coronal Plane
– divides the body into
a front and back

Celery Surgery

After you have
placed your patient
in the supine
position, assume
you are the surgeon
performing the
following 4 surgical
procedures on your
patient (celery).
1.
At the umbilicus, make a SUPERFICIAL
MIDSAGITTAL INCISION on the ventral surface of
your patient. Extend the incision inferiorly to the feet
(base of the stalk of celery).
2.
At the Superior end (head of patient), Make a DEEP
TRANSVERSE INCISION on the dorsal surface of
your patient. Do not transect your (cut into two
halves) patient.\
3.
Enter at the LATERAL surface at the umbilical level
and make a complete FRONTAL (CORONAL) incision
and proceed inferiorly (all the way to the feet).
4.
Make a COMPLETE MEDIAL NOTCH * on the inferior
end of your patient (celery). *a notch is a 3-D triangle
similar to the wedge made in the side of a tree as you
are chopping it down
