Organisation of the Body
A large part of beginning the study of anatomy and physiology is learning the spe-
cialised words that are used. This new terminology may seem daunting but the chal-
lenge 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 con-
structed 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 direc-
tion the transverse, sagittal & coronal planes of the body lie. Directional terms such
as: proximal/distal; deep/superficial; superior/inferior; lateral/medial; anterior/pos-
terior; 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 hypo-
chondriac, 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”?
A. Metabolism
B. Cellular respiration
C. Homeostasis
D. Physiology
Answer is A: The quoted statement is a definition of metabolism

, 2 1 Organisation 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.
4. To which of the following does the “tissue level” of structural organisation
refer?
A. atoms, ions, molecules and electrolytes
B. mitochondria, ribosomes, nucleus, endoplasmic reticulum
C. nephron, alveolus, villus, lobule
D. muscle, nervous, connective, epithelial
Answer is D: the listed structures are the four major tissue types.
5. The directional term “superior” in anatomy means which of the following?
A. cephalic
B. ventral
C. caudal
D. dorsal
Answer is A: cephalic refers to the head region. While superior refers to being
closer to the head than is the other anatomical structure in question.
6. Which of the following is the best definition of physiology?
A. The microscopic study of tissues and cells
B. The study of how the body works.
C. All the chemical processes that take place in the organelles of the body’s
cells.
D. The body’s automatic tendency to maintain a relatively constant internal
environment.
Answer is B: physiology is indeed the study of how the (healthy) body
functions.
