Healthcare professionals: MedicalTerminology. In this video, we will learn about the origin of medical terminology,the three word parts used to create medical terms, and how medical terms areformed and how to understand them. We will briefly look at the standardizedlanguage of medicine. Medical terms are made up of mostly Greek or Latin wordparts. If you understand the word parts separately, you will be able tounderstand more complex medical terms. It's impossible to memorize everydefinition in the medical dictionary, so a better method is to learn thedifferent parts that make up these complex medical terms. The word partsinclude a prefix, a root, and a suffix. The prefix comes at the beginning of aword, and it's used to add more information about the description, suchas the size, location, color, etc. Not all words have a prefix. The root is thebasic meaning of a term. It often describes the body part. The suffix comesat the end of a word, and describes the condition, procedure, disorder, or disease.Not all medical terms have a prefix, but they all have a root and a suffix. Whenyou see these word parts alone, in a dictionary, for example, you can identifythem by a hyphen or forward slash. A hyphen is used after a prefix, and it isused before a suffix. And a root word is followed by a forward slash. Now let'slook at roots. One root we will focus on in this lecture is the root tonsill/o, andthis is used for anything related to your tonsils. Another root is gastr/o and this is used for anything related to the stomach.We also will look at the root nat and this is related to birth, being born,babies. And another root is cardi/o and this is related to the heart. So let's work on adding suffixes toroots to create medical terms. We will look at the roots tonsill/o and gastr/o.The first suffix is -itis. -itis means inflammation. So if we add this suffix tothe root tonsill/o we get tonsillitis which means inflammation of the tonsils. We canalso add this suffix to the root gastr/o and we get gastritis, which meansinflammation of the stomach. Another suffix is -ectomy. -ectomy meanssurgical removal. If we add this to the root tonsill/o, we have tonsillectomy whichmeans that you have a surgical removal of your tonsils. Another suffix is -algia. Add this suffixto the root gastric/o, this suffix means pain, and if we add it to gastr/o or wegastralgia and this means stomach pain. Another common term for this isstomachache, but the medical term is gastralgia. Now let's look at some prefixes. And wewill use the roots nat/o and cardi/o. The first prefix is pre- and this meansbefore. If we add this to the root nat/o we get prenatal which means anythingrelated to the time before a baby is born. The opposite meaning of pre- is post-and this means after. If we add this to the root nat/o we get postnatal whichmeans anything related to the time after birth. Anotherprefix is tachy-. Tachy- means fast so we can add this prefix to the root cardi/o andwe get tachycardia which means fast heart action.The opposite meaning is Brady-. Brady- means slow, so we can also add this tothe root cardi/o and we get bradycardia which means slow heart action. Theprefixes in these words are pre-, post-, tachy-, and brady-, and we use these withroots to create medical terms. This is the end of the lecture. Afterlistening to this lecture, you should know the origin of medical terminology,the three word parts used to create medical terms, and how medical terms areformed and how to understand them.
