Seven Organizational Approaches
July 24, 2012
The seven organizational approaches when studying the human body is
body planes and body direction, body cavities, quadrants and regions, anatomy and
physiology, microscopic and macroscopic, body systems and medical specialties.
When studying the human body planes and direction you are dividing the body into
planes. The planes are divided into front and back, right and left, top and bottom. We
use body planes to help describe sections of the body. Anterior is the front of the body.
Distal means away from the body. Proximal toward the body. Dorsal is upper part of
the body. Ventral is the bottom of the body. When you are able to understand
anatomical directional term and body planes it will help you navigate from one area to
Body cavities are the internal organs of the human body. There are five body
cavities; cranial, spinal, thoracic, abdominal and pelvic. The cranial cavity stores the
brain, cranial nerves and other structures. Spinal cavity is the bones of the spinal
column, and contains spinal cord, nerves and other structures. Thoracic cavity contains
the lungs. Abdominal cavity is the muscles of the abdomen and bones of the spinal
column. Pelvic cavity is surrounded by the pelvic bones. Pelvic and abdominal cavity is
often referred as abdominopelvic cavity. This contains many organs. Some of the
organs are gastrointestinal, reproductive and urinary systems.
There are four quadrants; left upper (LUQ), right upper (RUQ), left lower (LLQ),
right lower (RLQ). You would make a horizontal line and a vertical line crossing the
navel. With regions of the abdominopelvic area it would be two horizontal lines and two
vertical lines, which would form a square around the navel. The nine regions are; right
