Medical terminology is the language used in the field of medicine and healthcare to describe and communicate information about the human body, diseases, procedures, and treatments. It is essential for healthcare professionals, including doctors, nurses, and medical assistants, to understand and use medical terminology accurately to ensure clear and precise communication. Medical terminology is typically made up of a combination of roots, prefixes, and suffixes. Here are some key components and examples: 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: 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. 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 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 Asuffix is a word ending that modifies a root. 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.” 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. Aprefix 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 will be followed by a hyphen to show that other parts will be added to the prefix to form a word. Medical terminology is the language used in the field of medicine and healthcare to describe and communicate information about the human body, diseases, procedures, and treatments. It is essential for healthcare professionals, including doctors, nurses, and medical assistants, to understand and use medical terminology accurately to ensure clear and precise communication. Medical terminology is typically made up of a combination of roots, prefixes, and suffixes. Here are some key components and examples: 1.Root Words: These are the basic building blocks of medical terms and often indicate the part of the body involved. For example: 1."Cardi-" refers to the heart, as in "cardiology" (the study of the heart). 2.Prefixes: These are added at the beginning of a word to modify its meaning. For example: 1."Sub-" means below or under, as in "subcutaneous" (beneath the skin). 3.Suffixes: These are added at the end of a word to modify its meaning or indicate a condition. For example: 1."-itis" means inflammation, as in "tonsillitis" (inflammation of the tonsils). 4.Combining Vowels: These are often used to make pronunciation easier and to join the root word with a prefix or suffix. For example: 1."Gastro-" (stomach) combines with "enteritis" (inflammation of the intestines) to create "gastroenteritis." 5.Abbreviations and Acronyms: The medical field often uses abbreviations and acronyms for common medical terms. For example, "CPR" stands for "Cardiopulmonary Resuscitation." medical terminology is essential for healthcare providers to effectively communicate and understand various aspects of patient care.
