5. ‘Anatomy is destiny.’
Sigmund Freud (1856–1939)
During most of the history of medicine, anatomy was
not only the destiny of those who ventured to practice
medicine but also the science of medicine. Even at the
turn of the 20th century, when Sigmund Freud used
the above quote to illustrate his claim that gender
determined one’s main personality traits, anatomy
was the major component of any medical curriculum.
With the development of technology and growth of
medical knowledge, anatomy—the scientific empire
and a foundation stone of medicine—has shrivelled to a
marginal and unattractive discipline, and a small part of
a medical curriculum with less and less direct dissection
on cadavers. Unjustly so, because at the same time
there has been an enormous development of imaging
methods to show and analyse the anatomy of a living
body, as well as microsurgical procedures where
anatomical details determine clinical practice.
As a student, you have to keep in mind that without
comprehensive morphological education and knowledge,
you will not be able to interpret the images you will
see daily on ultrasound, CT or MRI scans. Don’t be
overconfident in the power of technology, because it is
still you, a human being with knowledge of morphology,
who will have to interpret the morphology you see and
make the best clinical decision for your patient. To do this
you need to have a sound knowledge of anatomy, so that
you don’t see too much or too little.
With such new and ‘live’ anatomy in practice, teaching
anatomy must also change, not by just restructuring
the old content, but by introducing a completely new
concept. an@tomedia is indeed a new approach to
medical education: a single tool to replace different
didactic tools for transmission of three-dimensional
notion, it is at the same time a photographic atlas,
a gross anatomy dissector, a radiology overview, a set
of coloured overlays and an anatomy textbook.
General Anatomy, the first book in a series to follow
the nine an@tomedia interactive CD modules, is a most
valuable introduction to modern anatomy. It will show you
the human body from four perspectives: systems and
regions as the principles of body construction, and
dissection and imaging as the principles of body
deconstruction.
I’ll finish with another quote from a physician
and a famous novelist, W. Somerset Maugham
(1874–1965), who gave the following advice to first-year
medical students: ‘You will have to learn many tedious
things which you will forget the moment you have passed
your final examination, but in anatomy it is better to have
learned and lost than never to have learned at all.’ Don’t
be afraid of learning anatomy—you really need to know
it. And by mastering the principles and applications of
general anatomy, you will become not only a collector
of important facts but their master, too.

8. General Anatomy
This book is about the human body. Anatomy (from the
Greek: ‘apart + cut’ ) is the study of the structure of
the (human) body. The subject known as gross or
topographic anatomy includes the study of normal
structures (that can be seen with the naked eye) and
their arrangement into systems and regions. It is the
focus of this book. This is complemented by histology
(microscopic anatomy), embryology (developmental
anatomy) and the study of evolution (incorporating
comparative anatomy). Anatomy also interfaces with
physiology (through the correlation of structure with
function) and pathology (by the recognition of abnormal
structure), together with many clinical disciplines (by
applying knowledge of normal and abnormal structure).
The new vista of general anatomy introduces the
foundations of organ structure (before launching into
the detailed study of a particular body system) and the
general rules governing arrangement of organs within
regions (before launching into detailed descriptions of
relationships).
As well as being the foundation of systemic, regional
and practical perspectives, general anatomy is the glue
that holds the specifics together, as shown in Figure 1.
This book is primarily designed for medical, dental,
physiotherapy and health science students. It is equally
applicable for integrated (problem-based) courses or for
traditional (discipline-based) courses, as both require a
foundation of anatomical literacy coupled with an
understanding of the fundamentals.
Students will be equipped with the necessary
intellectual tools to then master specific subject matter
met in any sequence (see Figure 2).
The book is also designed for medical and allied health
practitioners to fill gaps left by a lack of emphasis on
principles in their own training (including associated
books), creating a bridge for new concepts and advances
in anatomy.
General Anatomy: Principles and Applications is
complemented by the (A New Approach
TO Medical Education Developments In Anatomy):
General Anatomy CD-ROM. However, either may be
used independently. This book has a linear (sequential)
organisation and provides a road map for the CD-ROM.
In contrast, the CD-ROM has a non-linear (hierarchical)
organisation with freedom for the user to choose the
order, rate and depth of study. It is also interactive, with
instant feedback to questions requiring identification of
objects on images and explanations of events (particularly
their associated clinical phenomena).
Principles and applications
This book is conceptual, a concept being the idea of an
object or an event. A principle is a recurring pattern of
linked concepts. Principles provide general rules relating

objects and events to each other. This enables deductive
(from the Latin: ‘from + lead’ ) reasoning where the
specifics are examples derived from a generalisation.
In contrast, inductive (Latin: ‘to + lead’ ) reasoning allows
patterns to emerge after gathering all the detailed
information and reflecting on them, the specifics lead
to generalisations. Versatile learners require both forms
of reasoning.
Essential (core) factual information is trapped between
the pincers of a principle and its application. The
challenge for any curriculum is to extract this from
extraneous descriptive detail (see Figure 3). The
application of anatomical principles is primarily to clinical
contexts. The prime goal of this book is to help the
learner competently (and confidently) meet new situations
in future practice, armed with the capacity to reason
from first principles.
Understanding anatomical principles is the basis
for recognising clinical manifestations of disease
processes.
Anatomical principles are comprehensively
constructed, organised and explained in this book.
They are missing or receive only scant reference in
introductory sections of most anatomy textbooks.
A goal of this book is neither to replace nor to attempt
to cover the entire scope of large descriptive books, but
to complement these books, helping to make them more
meaningful and easier to learn from.
New directions
This book incorporates both theoretical and practical
perspectives. The former enables the body to be
constructed from its components, systemically and
regionally, while the latter enables an intact body to
be deconstructed, with the hands, e.g. dissection or
clinical procedures, or with the eyes, e.g. imaging,
endoscopy.
Looking forward
Even if the human body may not seem to change, ways
of viewing it, conceptualising it and intervening on it
certainly do.
New developments in viewing the body are occurring
through special imaging techniques, e.g. three-
dimensional reconstructions.
New concepts are being developed, e.g. angiosomes,
venosomes and neurosomes, and new terms will be
required to replace outmoded terms.
New advances are continually evolving in surgical
techniques, such as endoscopic or reconstructive
surgery, and in interventional radiology, such as balloon
angioplasty.
Looking back
With new discoveries, there is also a need to be aware
of anatomical variants that may impact on them. This
requires accessing past documentation of such variants,
which have been described in great detail although not
in the context of surgical interventions previously
unimaginable. Furthermore, it is increasingly important
that investigators of anatomy obtain access to cadavers
to verify surgical techniques (ideally) prior to them being
performed on living patients.
Complications resulting from a new procedure can be
due to the presence of an unexpected anatomical variant.
The dissecting room may be used to refine the technique
to take this possibility into account rather than abandon
an otherwise valid surgical advance.
Thirty years ago, who would have thought that cardiac
surgeons would now be contemplating variance of radial
and ulnar arterial supply to the hand when grafting
coronary arteries?

DESIGN FEATURES OF THIS BOOK
Evolutionary history of the human body
All animals evolved from a common ancestor. Humans (Homo sapiens) share
many features with other animals on our family tree but may be categorised via
a hierarchy of progressively more specific characteristics.
THE HUMAN ‘IDENTITY CARD’ IS:
Kingdom: Animal
Superphylum: Coelomate
Phylum: Chordate
Subphylum: Vertebrate
Class: Mammal
Order: Primate
Family: Hominid
Genus: Homo
Species: Homo sapiens
Developmental history of the human body
During development from a single cell (itself the product of fertilisation of an
ovum by a sperm) to an adult human (male or female), features from each of the
above categories appear, at least transiently. For example, all developing verte-
brates acquire precursors of gills and a tail, even though they may subsequently
disappear or become modified beyond recognition.
It is also no accident that this reflects the evolution from unicellular organism
to Homo sapiens, as at the earliest stages of their development embryos of differ-
ent animals tend to resemble each other (a human embryo even up to six weeks
is almost indistinguishable from one of other mammals). However, from then
on they progressively diverge, both in form (external appearance) and in struc-
ture (internal construction). The respective genetic blueprint (modified by
mutations) predetermines this. According to Haeckel’s Biogenetic Law:
Ontogeny recapitulates phylogeny.

INTRODUCTION
‘ANATOMY ACCOMMODATES ANCESTRY’
Visceral systems
Viscera (L. ‘sticky’) have a variety of structures and func-
tions. Collectively they are responsible for regulating the
internal environment of the body. Viscera occupy cavities
within the body framework and are involved with secre-
tion, excretion, digestion and absorption.
Viscera are either hollow or solid. They are typically
organised into systems composed of a tract of hollow
tubes and associated solid glands.
Respiratory system
The respiratory system consists of the respiratory tract
and lungs (Fig. 8.1). The tract is made up of the nasal
cavity, pharynx (nasal and oral parts), larynx, trachea and
bronchial tree. It is shared with the digestive tract where
the pathways for air and for food intersect.
Digestive system
The digestive system consists of hollow tubes—the diges-
tive (alimentary) tract—together with solid viscera (the
associated glands). The tract extends from the mouth to
the anus. It is made up of the pharynx (oral and laryngeal
parts), oesophagus, stomach, small intestine and large
intestine. The associated glands are the (paired) salivary
glands and the (unpaired) pancreas. The digestive system
also includes the biliary system, made up of the liver, gall
bladder and biliary tree (Fig. 8.2).

numerous folds to increase their surface area for absorp-
tion, e.g. in the small intestine (Fig. 8.6).
Sites of normal constrictions
The lumen of a tubular viscus may have a dilatation termed
an ampulla (L. ‘flask’) or constrictions at particular sites.
Normal constrictions of the lumen tend to occur at
the beginning and end of a tubular viscus.
These are often associated with orifices, mucosal folds
or thickenings of the muscle wall to control passage
through the lumen.
The beginnings and ends of the ureters and the urethra
have normal constrictions of the lumen (Fig. 8.7).
Normal constrictions may also occur where adjacent
structures compress a tubular viscus at particular sites
along its course. Such normal constrictions occur where
the ureter crosses the pelvic brim and where the urethra
(in the male) passes through the urogenital diaphragm.

OBSTRUCTION OF A TUBULAR VISCUS
Impairment of propulsion through a tubular viscus is termed
visceral obstruction. This may occur directly by mechanical
factors or indirectly by interference with its neurovascular supply
(affecting wall function and/or vitality). Obstruction of a tubular
viscus may be classified anatomically into three types (according
to its relationship with the wall) (Fig. 8.8).
Extramural (external) obstruction comes from outside
compression of a tubular viscus, e.g. by a tight hernial orifice or
fibrous adhesions.
Intramural obstruction arises from within the wall, e.g. by a
mucosal tumour, spasm of smooth muscle or occlusion of arteries
supplying the wall.
Intraluminal (internal) obstruction is from a blockage within
the lumen, e.g. by a foreign body.
Obstruction of a tubular viscus causes impaired passage of
luminal contents.This, in turn, tends to produce distension (prox-
imal to the obstruction), pain (due to stretching of the distended
viscus) and, initially, increased peristalsis (to overcome the
obstruction). As an example, intestinal obstruction typically
produces the triad of constipation (reduced passage of faeces
and flatus), abdominal distension and pain. These symptoms
may be accompanied by altered bowel sounds (from peristalsis),
detected on auscultation.

■ Anatomical principles highlighted
(also collated in a review section
for easy access)
The photographs show concrete reality;
some reveal the body in all its complexity.
Certain photographs display the naked
exterior of the body, others the exposed interior,
which by their very nature is graphic (particularly
those at autopsy). Images of embalmed and
dissected human remains are provided to
be educational, rather than sensational. In
particular, they provide access to anatomical
material that is not readily available, e.g. fetal
dissections.
■ Diagrams (of events)
The complementary diagrams are abstract
conceptualisations either showing what cannot
be made visible or helping provide a way to see
what is otherwise obscured by complexity. All of
the images (both photographs and diagrams)
have been made as simple as possible but not
simpler.
