Included in the text are simple, nontechnical descriptions of pathological conditions, medical instruments and clinical procedures. The medical terms are introduced within the context of a body system or medical specialty and each set of exercises provides the student with the opportunity to learn, review and assess new words. Each unit includes a case history exercise that outlines the presentation, diagnosis and treatment of a specific medical condition. Once complete, the exercises will form a valuable reference text. No previous knowledge of medicine is required to follow the text and, to ensure ease of use, the more complex details of word origins and analysis have been omitted. The book will be of great value to anyone who needs to learn medical terms quickly and efficiently.

Once you have understood the elementary rules of medical word building, complete Units 1-21, which are based on different medical topics. The units can be studied in sequence or independently. For ease of use each unit has the same basic plan and is arranged into: WORD EXERCISES AN ANATOMY EXERCISE A CASE HISTORY A WORD CHECK A SELF-ASSESSMENT The different parts of each unit are indicated by icons. The word exercise icon indicates a written exercise that can be completed using the Exercise Guide at the beginning of each unit or knowledge acquired during this course of study. The answers to the word exercises are on p. 275. The anatomy exercise icon indicates you should complete the anatomy exercise relating to a body system. In this exercise you relate combining forms of medical roots to their position in the body. Check the meanings of the root words using the Quick Reference box. The case history icon indicates an account of a medical case history. The purpose of this exercise is to understand the medical terms associated with disease presentation, investigation and treatment. Some of the case histories may seem difficult to follow because of the terminology used when doctors write formal reports. To assist your understanding, a Word Help box is included with each case listing the meanings of difficult or unfamiliar words. In each case history, try to gain an overall picture of the health care required for successful treatment of the patient. Answers to the exercise that accompanies each case can be found with the answers to the word exercises on p. 275. viii AN INTRODUCTION TO MEDICAL TERMINOLOGY The word check icon indicates you should complete the Word Check that lists all prefixes, combining forms and suffixes used in a unit. Try to do this from memory and then correct any errors you have made. Errors can be corrected using the Exercise Guide or the Quick Reference box that follows each Case History. The glossary on p. 319 can also be used. The self-assessment icon indicates a series of self-assessment tests. Aim to complete the tests using knowledge gained from studying each unit and record your score in the boxes provided with each test. Check your answers on p. 299. Introduction Example 1 GASTROTOMY Objectives First we can split the word and examine its individual components: Once the introduction is complete you should be able to: name and identify components of medical words split medical words into their components build medical words using word components. The word root Students beginning any kind of medical or paramedical Roots are the basic medical words. Most are derived course are faced with a bewildering number of complex from Greek and Roman (Latin) words. Others have their medical terms. Surprisingly it is possible to understand origins in Arabic, Anglo-Saxon and German. Some early many medical terms and build new ones by learning Greek words have been retained in their original form relatively few words that can be combined in a variety whilst others have been latinized. In their migrations of ways.

In our first example we have added the combining Precise medical terms are used when medical records vowel o to the root gastr. and letters are completed. They are also used when doctors discuss a patient and when medical material is published. Jhe suffix The terms you will use in this book describe common The suffix follows the word root and is found at the end diseases and disorders, instruments, diagnostic tech- of the word. It also adds to or modifies the meaning of niques and therapies. the word root. In our first example we have used the suffix -tomy which always means to form an incision. The components of medical words We can now fully understand the meaning of our first medical word: In this introduction you will learn how to split medical terms into their components and deduce their mean- ings. Skills developed here will enable you to derive the meanings of unfamiliar medical words and improve your ability to understand medical literature. Let us begin by using a medical word associated with an organ with which you are familiar, the stomach:  2 AN INTRODUCTION TO MEDICAL TERMINOLOGY FOR HEALTH CARE The meaning of gastrotomy is - incision into the stom- Key Point ach. Gastrotomy is a name used by surgeons to describe The components of medical words are: an operation in which a cut is made into the wall of the stomach. Jhe combining form In our first example the root gastr can be combined with the vowel o to make gastro. This word component is called a combining form of a word root, i.e. The use of prefixes, combining Word root + combining vowel = combining forms and suffixes form There are certain simple 'rules' which need to be gastr + o = gastro applied when building and analysing medical words. Most combining forms end in o and we will be using To practise using these rules, some new combining many of them in the exercises that follow. forms are introduced. Don't worry about their mean- ings at the moment, we will study them in a later unit. Now we have learnt the meaning of our first root we can use it again with a new word component: Example 2 EPIGASTRIC Rule /: Joining a combining form to a suffix If we add the suffixes -logy, meaning study of, and -algia, meaning condition of pain, to the combining form gastr/o we can make two new words: gastr/o + -logy = gastrology (study of the stomach) Here we have split the word into its components and gastr/o + -algia = gastralgia (condition of we can see it begins with a prefix that appears before pain in the the root gastr. stomach) Notice that in gastrology the combining vowel o has been left in place whilst in gastralgia it has been The prefix dropped. The o has been dropped in gastralgia because -algia begins with a, a vowel. Gastroalgia is not used The prefix precedes the word root and changes its and it would be more difficult to pronounce. meaning. The prefix epi- means upon and so it modifies the word to mean upon or above the stomach. Prefixes, like roots and suffixes, are also derived from Greek and Key Point Latin words. When a combining form of a root is joined to a suffix, the combining vowel is left in place if the suffix begins with a The suffix -ic meaning pertaining to was also used in letter other than a vowel. our second example so we can now write the full mean- ing of epigastric: Here are some more examples where the vowel is left in place because the suffix begins with a letter other than a vowel: gastr/o + -tomy = gastrotomy (incision into This is a word root This is a suffix meaning the stomach) upon/above meaning stomach pertaining to gastr/o 4- -scope = gastroscope (instrument to view the stomach) Here are some examples where the vowel is dropped: The full meaning of epigastric is - pertaining to above or upon the stomach. gastr/o + -itis = gastritis (inflammation of the stomach) gastr/o + -ectomy = gastrectomy (removal of the stomach)  INTRODUCTION 3 Example 3 GASTROENTEROLOGY WORD EXERCISE I GASTR/O ENTER/0 LOGY Use Rule 1 to join the combining forms of word roots and suffixes to make medical words.

(d) hepat/o + -megaly = (e) hepat/o + -oma = Here are some more examples: pylor/o + gastr/o + ectomy = pylorogastrec- Rule 2: Joining the combining forms of tomy duoden/o + enter/o + stomy = duodeno- two word roots enterostomy Some medical words contain two or more combining forms of roots, as in Example 3. WORD EXERCISE 2 Use Rules 1 and 2 to join the combining forms of two roots with suffixes to make medical words. The meanings of the words will be studied in following units. The first has been completed for you.

There are a few exceptions to this rule which are hyphenated e.g. pharyngo-oral.  4 AN INTRODUCTION TO MEDICAL TERMINOLOGY FOR HEALTH CARE Rule 3: Joining a prefix to a root Reading and understanding medical When a prefix that ends in a vowel is added to a root words that begins with a vowel or 'h', the vowel of the prefix is Now you have learnt the basic principle of building dropped. medical words, you should be able to deduce the mean- If we examine our second example, epigastric, again, ing of an unfamiliar word from the meaning of its com- here the vowel Y of epi- was retained because the root ponents.
