  5. 5. 1267-00 FM 07/07/03 14:22 Page v Preface E very career in health care begins with learning the vast and challenging language of medical terminology. Without adequate learning and teaching resources, it can be an overwhelming challenge for students and faculty. This new edition of Medical Terminology: An Illustrated Guide meets that challenge with a clear organizational scheme, full-color illustrations with a strong clinical focus, a wide array of effective pedagogical features, a variety of activities, and useful ancillaries to make teaching and learning more effective. Because the content is so accessible and logically organized, the text can be used as part of classroom instruction, for independent study, or for distance learning. Organization and Approach Medical Terminology: An Illustrated Guide takes a stepwise approach to learning the language of medical terminology. Part 1 describes how medical terms are built, and Part 2 introduces body structure, disease, and treatment. These chapters should be studied before proceeding to Part 3, which describes each of the body systems. Individual chapters also build on knowledge in stages, with Key Terms sections listing those terms most commonly used and specialized terms included in a later section entitled Supplementary Terms. The latter terms may be studied according to time available and student needs. Each chapter opens with a chapter outline and a list of student objectives—goals to be accomplished by the completion of the chapter. In Part 3, the chapters begin with an overview of the normal structure and function of the system under study, followed by a list of key terms with definitions (the roots used in the accompanying chapter exercises are included in these definitions). Word parts related to each topic are then presented and illustrated, along with exercises on the new material. Next, there is an overview of clinical information pertaining to the system, also followed by a list of key terms with definitions. Many chapters contain displays that unify and simplify material on specific topics. New to this edition is information on complementary and alternative medicine and special interest boxes with information on word derivations and usage. v

  16. 16. 1267-01 CH01 07/07/03 14:28 Page 5 CHAPTER 1 • CONCEPTS OF MEDICAL TERMINOLOGY 5 M edical terminology is a special vocabulary used by health care professionals for effective and accurate communication. Because it is based mainly on Greek and Latin words, medical terminology is consistent and uniform throughout the world. It is also efficient; although some of the terms are long, they often reduce an entire phrase to a single word. The one word gastroduodenostomy, for example, stands for “a communication between the stomach and the first part of the small intestine” (Fig. 1-1). The medical vocabulary is vast, and learning it may seem like learning the entire vocabulary of a foreign language. Moreover, like the jargon that arises in all changing fields, it is always expanding. Think of the terms that have been added to our vocabulary with the development of computers, such as software, megabyte, search engine, e-mail, chat room. The task seems overwhelming, but there are methods that can aid in learning and remembering words and can even help in making informed guesses regarding the meanings of unfamiliar words. Most medical terms can be divided into component parts—roots, prefixes, and suffixes—that maintain the same meaning whenever they appear. By learning these meanings, you can analyze and remember many words. Word Parts The fundamental unit of each medical word is the root. This establishes the basic meaning of the word and is the part to which modifying prefixes and suffixes are added. A suffix is a short word part or series of parts added at the end of a root to modify its meaning. In this book suffixes are indicated by a dash before the suffix, such as -itis. A prefix is a short word part added before a root to modify its meaning. In this book prefixes are indicated by a dash after the prefix, such as pre-. Shown diagrammatically: Prefix Prefix Root Word Words are formed from roots, prefixes, and suffixes. Stomach Duodenum Root Duodenal anastomosis FIGURE 1-1. Gastroduodenostomy Suffix Suffix
  17. 17. 1267-01 CH01 07/07/03 14:28 Page 6 6 PART 1 • INTRODUCTION TO MEDICAL TERMINOLOGY Kidney Ureter Bladder Urethra FIGURE 1-2. The Greek root nephr and the Latin root ren are used to refer to the kidney, an organ of the urinary system. The simple word learn can be used as a root to illustrate. If we add the suffix -er to form learner, we have “one who learns.” If we add the prefix re- to form relearn, we have “to learn again.” Not all roots are complete words. In fact, most medical roots are derived from other languages and are meant to be used in combinations. The Greek word kardia, for example, meaning “heart,” gives us the root cardi. The Latin word pulmo, meaning “lung,” gives us the root pulm. In a few instances, both the Greek and Latin roots are used. We find both the Greek root nephr and the Latin root ren used in words pertaining to the kidney (Fig. 1-2). Note that the same root may have different meanings in different fields of study. The root myel means “marrow” and may apply to either the bone marrow or the spinal cord. The root scler means “hard” but may also apply to the white of the eye. Cyst means “a filled sac or pouch” but also refers specifically to the urinary bladder. You will sometimes have to consider the context of a word before assigning its meaning. Compound words contain more than one root. The words eyeball, bedpan, frostbite, and wheelchair are examples. Some compound medical words are cardiovascular (pertaining to the heart and blood vessels), urogenital (pertaining to the urinary and reproductive systems), and lymphocyte (a white blood cell found in the lymphatic system). Combining Forms When a suffix beginning with a consonant is added to a root, a vowel (usually an o) is inserted between the root and the suffix to aid in pronunciation.
  18. 18. 1267-01 CH01 07/07/03 14:28 Page 7 CHAPTER 1 • CONCEPTS OF MEDICAL TERMINOLOGY Root O Root A combining vowel may be added between a root and a suffix. O 7 Suffix Suffix Word Thus, when the suffix -logy, meaning “study of,” is added to the root neur, meaning “nerve or nervous system,” a combining vowel is added: neur + o + logy = neurology (study of the nervous system) Roots shown with a combining vowel are called combining forms. Root Root A root with a combining vowel is often called a combining form. O O Combining form In this text, roots are given with their most common combining vowels added after a slash and are referred to simply as roots, as in neur/o. A combining vowel usually is not used if the ending begins with a vowel. The root neur is combined with the suffix -itis, meaning “inflammation of,” in this way: neur + itis = neuritis (inflammation of a nerve) There are some exceptions to this rule, particularly when pronunciation or meaning is affected, but you will observe these as you work. Word Derivations As mentioned, most medical word parts come from Greek (G) and Latin (L). The original words and their meanings are included in this text only occasionally. They are interesting, however, and may aid in learning. For example, muscle comes from a Latin word that means “mouse” because the movement of a muscle under the skin was thought to resemble the scampering of a mouse. The coccyx, the tail end of the spine, is named for the cuckoo because it was thought to resemble the cuckoo’s bill (Fig. 1-3). For those interested in the derivations of medical words, a good medical dictionary will provide this information. Several such books are listed in the bibliography at the end of this text. Pronunciation Phonetic pronunciations are provided in the text at every opportunity, even in the answer keys. Take advantage of these aids. Repeat the word aloud as you learn to recognize it in print. Be aware that word parts may change in pronunciation when they are combined in different ways. The following pronunciation guidelines apply throughout the text.

The coccyx of the spine looks like the bill of a cuckoo. (Reprinted with permission from Cohen BJ, Wood DL. Memmler’s The Human Body in Health and Disease. 9th Ed. Philadelphia: Lippincott Williams & Wilkins, 2000.) A vowel (a, e, i, o, u) gets a short pronunciation if it has no pronunciation mark over it, such as: a as in hat e as in met i as in bin o as in some u as in run A short line over the vowel gives it a long pronunciation: _ a _ as in say e as in tea _ i as in lie _ o as in hose _ u as in sue The accented syllable in each word is shown with capital letters. Note that pronunciations may vary from place to place. Only one pronunciation for each word is given here, but be prepared for differences.

Pronunciations may vary from country to country, even in different regions of the same country. Think how easy it is to distinguish a southern accent and one from the midwest or northeastern United States. The general rule is to include the most common pronunciation. The word gynecology is usually pronounced with a hard g in the United States, but in many – – areas a soft g is used, as in jin-e-KOL-o -je . Words pertaining to the cerebrum (largest part of the brain) may have an accent on different syllables. The adjective is usually pronounced with the accent on the second syllable (se-REbral), but in cerebrum (SER-e-brum) and cere– – brospinal (ser-e-bro -SPI -nal), the accented syllable differs. The name for the first part of the small intestine (duodenum) is often pronounced – – – du -o -DE -num, although the pronunciation – du -O-de-num is also acceptable. When extreme, some alternate pronunciations can sound like a foreign language. The word we pronounce as SKEL-e-tal is pronounced in some other English-speaking countries as ske-LE-tal. Soft and Hard c and g _ _ A soft c, as in racer, will be written_ s (RA-ser). A hard c, as in candy, will be written as k (KAN-d e ). A soft as _ g, as in page, will be written as j (pa j). A hard g, as in grow, will be written as g (gro ). Silent Letters and Unusual Pronunciations A silent letter or unusual pronunciation can be a problem, especially if it appears at the start of a word that you are trying to look up in the dictionary. See Table 1-1 for some examples. The combinations in Table 1-1 may be pronounced differently when they appear within a word, as in apnea _ _ (AP-ne -a), meaning cessation of breathing; nephroptosis (nef-rop-TO -sis), meaning dropping of the kidney; _ prognosis (prog-NO-sis), meaning prediction of the outcome of disease. Symbols Symbols are commonly used in case histories as a form of shorthand. Some examples are L and R for left and right; ↑ and ↓ for increase and decrease. A list of common symbols appears in Chapter 7 and in Appendix 1. Abbreviations Like symbols, abbreviations can save time, but they can also cause confusion if they are not universally understood. Usage varies in different institutions, and the same abbreviation may have different meanings in different fields. An acronym is an abbreviation formed from the first letter of each word in a phrase. Some

In computerese, RAM stands for “random access memory.” Acronyms have become popular for saving time and space in naming objects, organizations, and procedures. Only the most commonly used abbreviations are given. These are listed at the end of each chapter, but a complete alphabetical list appears in Appendix 2. An abbreviation dictionary also is helpful. Words Ending In x When a word ending in x has a suffix added, the x is changed to a g or a c. For example, pharynx (throat) be_ comes pharyngeal (fa-RIN-je -al), to mean_“pertaining to the throat”; coccyx (terminal portion of the vertebral column) becomes coccygeal (kok-SIJ-e -al), to mean “pertaining to the coccyx”; thorax (chest) becomes _ _ thoracotomy (thor-a-KOT-o-me) to mean “an incision into the chest.” Suffixes Beginning With rh When a suffix beginning with rh is added to a root, the r is doubled: hem/o (blood) + -rhage (bursting forth) = hemorrhage (a bursting forth of blood) men/o (menses) + -rhea (flow, discharge) = menorrhea (menstrual flow)

During the course of her treatment, she was seen by several specialists. For pain in her knee and hip joints, she was referred to an orthopedist. For migraine headaches and blurry vision, she consulted a neurologist. For pain on urination and occasional bloody urine, she saw a urologist. Later, for a persistent dry cough and problems resulting from a fractured nose, she was referred to an otorhinolaryngologist. During her initial course of treatment, she had a CT scan of her abdomen and brain and an MRI of her hip and knee. Both imaging studies required her to lie motionless on her back for 45 minutes. Several months after the accident, D.S. was still experiencing some discomfort, and she decided to investigate alternative therapies. She made an appointment with a naturist practitioner who specialized in homeopathy and herbal medicine. Before her appointment, she browsed in the Nutra-Medica Shop, which carried nutritional supplements, vitamin and mineral products, homeopathic remedies, and herbal formulas. She planned to ask the therapist about some of the products that she saw there, which included remedies with the trade names Pneumogen, Arthogesia-Plus, Renovite, Nephrostat, and Hematone.

A suffix may indicate that the word is a noun or an adjective and often determines how the definition of the word will begin. For example, using the root myel/o, meaning “bone marrow,” the adjective ending -oid forms the word myeloid, which means “like or pertaining to bone marrow.” The ending -oma produces myeloma, which is a tumor of the bone marrow. Adding another root, gen, which represents genesis or origin, and the adjective ending -ous forms the word myelogenous, meaning “originating in bone marrow.” The suffixes given in this chapter are general ones that are used throughout medical terminology. Additional suffixes will be presented in later chapters, as they pertain to disease states, medical treatment, or specific body systems. Noun Suffixes TABLE 2-1 Suffixes That Mean “Condition Of” SUFFIX -ia -ism -sis* -y EXAMPLE phobia – – FO -be -a alcoholism – AL-ko -hol-izm acidosis – as-i-DO -sis tetany – TET-a-ne DEFINITION OF EXAMPLE persistent and exaggerated fear impaired control of alcohol use acid condition of body fluids sustained muscle contraction *The ending -sis may appear with a combining vowel, as -osis, -iasis, -esis, or -asis. The first two of these denote an abnormal condition. Exercise 2-1 Write the suffix that means “condition of” in each of the following words: 1. egotism (exaggerated self-importance) – – E -go-tizm 2. dysentery (intestinal disorder) _ DIS-en-ter-e 3. insomnia_ (inability to sleep) in-SOM-ne-a 4. parasitism (infection with parasites or behaving as a parasite) PAR-a-sit-izm 5. thrombosis (having a blood clot in a vessel) (Fig. 2-1) _ throm-BO-sis -ism

The suffix -thon is taken from the name of the Greek town Marathon, from which news of a battle victory was carried by a long-distance runner. It has been attached to various words to mean a contest of great endurance. We have bike-athons, dance-athons, telethons, even major charity fund-raisers called thona-thons. The adjective ending -ish, as in Scottish, can be added to imply that something is not right on target, as in largish, softish, oldish. In science and medicine, the ending -tech is used to imply high technology, and -pure may be added to inspire confidence, as in the company name Genentech and the Multi-Pure water filter. The ending -mate suggests a helping device, as in HeartMate, a pump used to assist a damaged heart Adjective Suffixes The suffixes below are all adjective endings that mean “pertaining to” or “resembling” (Table 2-3). There are no rules for which ending to use for a given noun. Familiarity comes with practice. When necessary, tips on proper usage are given in the text. TABLE 2-3 Suffixes That Mean “Pertaining to” or “Resembling” SUFFIX -ac -al -ar -ary -form -ic* -ical (ic + al) -ile -oid -ory -ous EXAMPLE cardiac _ CAR-de-ak skeletal SKEL-e-tal muscular _ MUS-ku-lar dietary _ _ di -e-tar-e muciform _ MU-si-form metric ME-trik anatomical an-a-TOM-i-kl febrile _ FEB-ri l toxoid TOK-soyd respiratory _ RES-pi-ra-tor-e venous _ VE -nus DEFINITION OF EXAMPLE pertaining to the heart pertaining to the skeleton pertaining to muscles pertaining to the diet like or resembling mucus pertaining to a meter (unit of measurement) (Fig. 2-3) pertaining to anatomy pertaining to fever resembling toxin (poison) pertaining to respiration pertaining to a vein *For words ending with the suffix -sis, the first s in the ending is changed to t before adding -ic to form the adjective, as in psychotic, pertaining to psychosis (a mental disorder), or diuretic, pertaining to diuresis (increased urination).

Exercise 2-3 Identify the suffix meaning “pertaining to” or “resembling” in each of the following words: 1. salivary (pertaining to saliva) _ SAL-i-var-e 2. pelvic (pertaining to the pelvis) PEL-vik 3. neurotic (pertaining to neurosis) _ nu-ROT-ik 4. fibrous (pertaining to fibers) _ FI -brus 5. epileptiform (resembling epilepsy) ep-i-LEP-ti-form 6. ovoid (resembling an egg) OV-oyd 7. topical (pertaining to a surface) TOP-i-kal 8. virile (masculine) VIR-il 9. vocal (pertaining to the voice) _ VO-kal 10. surgical (pertaining to surgery) SUR-ji-kal 11. nuclear (pertaining to a nucleus) _ _ NU-kle-ar -ary

Table 2-4 gives some general rules for the formation of plurals along with examples. The plural endings listed in column 2 are substituted for the word endings in column 1. Some Exceptions to the Rules There are exceptions to the rules above for forming plurals, some of which will appear in later chapters. For example, the plural of virus is viruses, and serums is sometimes used instead of sera. An -es ending may be added to words ending in -ex or -ix to form a plural, as in appendixes, apexes, and indexes. Some people, in error, use phalange as the singular of phalanges. Words ending in -oma, meaning “tumor,” should be changed to -omata, but most people just add an s to form the plural. For example, the plural of carcinoma (a type of cancer) should be carcinomata, but carcinomas is commonly used.

He was fatigued, yet unable to sleep through the night. He also had a mild fever, night sweats, occasional dizziness, double vision, and mild crampy abdominal pain accompanied by intermittent diarrhea. In addition, he had a nonhealing wound on his ankle from an insect bite. He made an appointment with his family doctor, an internist. On examination, E.G. was febrile (feverish) with a temperature of 101°F. His heart and lungs were normal, with a slightly elevated heart rate. His abdomen was tender to palpation (touch), and his bowel sounds were active and gurgling to auscultation (listening with a stethoscope). His skin was dry and warm. He had symmetrical areas of edema (swelling) around both knees and tenderness over both patellae (kneecaps). The ulceration on his left lateral ankle had a ring of necrosis (tissue death) surrounding an area of granulation tissue. There was a small amount of purulent (pus-containing) drainage. E.G.’s doctor ordered a series of hematology lab studies and stool cultures for ova and parasites. The doctor suspected a viral disease, possibly carried by mosquitoes, indigenous to tropical rain forests. He also suspected a form of dysentery typically caused by protozoa. E.G. was also possibly anemic, dehydrated, and septic (infected). The doctor was confident that after definitive diagnosis and treatment, E.G. would gain relief from his insomnia, diplopia (double vision), and dizziness.

Define a prefix and explain how prefixes are used. 2. Identify and define some of the prefixes used in medical terminology. 3. Use prefixes to form words used in medical terminology. 28 3
  40. 40. 1267-03 CH03 07/07/03 14:30 Page 29 CHAPTER 3 • PREFIXES 29 A prefix is a short word part added before a word or word root to modify its meaning. For example, the word lateral means “side.” Adding the prefix uni-, meaning “one,” forms unilateral, which means “affecting or involving one side.” Adding the prefix contra-, meaning “against or opposite,” forms contralateral, which refers to an opposite side. The term equilateral means “having equal sides.” Prefixes in this book will be followed by a hyphen to show that other parts will be added to the prefix to form a word. This chapter introduces most of the prefixes used in medical terminology. Although the list is long, almost all of the prefixes you will need to work through this book are presented here. There is just one short additional chart of prefixes related to position in Chapter 5 on body structure. The meanings of many of these prefixes will be familiar to you from words that are already in your vocabulary. The words in the charts are given as examples of usage. Almost all of them will reappear in later chapters. If you forget a prefix as you work, you may refer to this chapter or to the alphabetical lists of word parts and meanings in the glossary.

In everyday life, the prefix efor electronic has spread to words such as e-mail, e-commerce, e-Bay, and many more. X- for extreme appears in X-games and other X-sports. The prefix endo- in the names of many surgical instruments signifies new endoscopic instruments that are longer and thinner and have smaller working tips to be used in areas where there is minimal access. Some examples are endoscissors, endosuture, endocautery, endograsper, and endosnare. Health care products designed for specific age groups are also encoded by prefixes. Geri-, pertaining to old age, as in geriatrics, appears in geri-chair, geri-pads, geri-jacket, and the patent medicine Geritol, among others. Pedi- or pedia-, meaning “child,” is found in the names pedicath, pedi-dose, pedi-set (instruments), and Pedialyte, a product used for children to replace fluid and electrolytes.

Intraoperatively, she was given spinal anesthesia and positioned on an operating room table, with her left hip elevated on a small pillow. Intravenous antibiotics were given before the incision. Her left hip was repaired with a bipolar hemiarthroplasty. Postoperative care included maintaining the left hip in abduction, blood and fluid replacement, physical therapy, and vigilance for development of avascular necrosis and possible dislocation. Case Study 3-2: Intertrochanteric Fracture A.R., age 88, slipped on the wet grass and fell while gardening in his back yard. His neighbor was unable to help him to a standing position and called for an ambulance. A.R. had excruciating pain in his right leg, which was externally rotated, slightly shorter than his left leg, and adducted. Preoperative radiographs showed a non-displaced right intertrochanteric fracture. Intraoperatively, Mr. R. was given spinal anesthesia and positioned on an orthopedic table with his right hip abducted and secured in traction. He had an open reduction and internal fixation with a compression screw and side plate with screws. His postoperative recovery was unremarkable, although he was at risk for deep vein thrombosis, that is, blood clots in his legs. He was discharged to a rehabilitation facility for several weeks of physical therapy and assistance with activities of daily living, such as personal hygiene, dressing, eating, ambulating, and toileting.
