Chapter 1
Organization of the Body
A large part of beginning the study of anatomy and physiology is learning the specialised words that are used. This new terminology may seem daunting but the challenge lies in its unfamiliarity rather than its difficulty of comprehension. You must
expect to encounter a lot of new words and be prepared to learn them over the
course of your study. Many of the words contain information as the words are constructed with a prefix and a suffix or a stem that identifies the word as referring to a
specific part of anatomy or physiology. This sometimes makes the words rather long
or unusual.
You should know what the anatomical position of the body is and in what direction the transverse, sagittal & coronal planes of the body lie. Directional terms such
as: proximal/distal; deep/superficial; superior/inferior; lateral/medial; anterior/posterior; caudal/cephalic allow the location of one anatomical feature to be placed
relative to another. The dorsal and ventral body cavities are located on different
sides of the body and contain different organs. For ease of communication, the
abdomen is divided into nine regions: right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right inguinal, hypogastric (or
pubic), left inguinal regions. You should know the difference between physiology
and anatomy and the definitions of metabolism, anabolism and catabolism.
1. Which of the listed terms is described by: “All the chemical processes that take
place in the organelles and cytoplasm the cells of the body”?

2. Which major organ lies deep to the right hypochondriac region?
A. The stomach
B. The spleen
C. The liver
D. The duodenum
Answer is C: hypochondriac = below the rib cartilage; liver is located mostly
on the right side.
3. Which plane of the body divides it into dorsal and ventral regions?
A. Transverse
B. Axial
C. Coronal
D. Sagittal
Answer is C: dorsal and ventral = front and back – a coronal section so divides
the body into these sections.
