常用的词根、前后缀和常见疾病病名Why Do We Study Medical Terminology? The number of Medical words are enormous. How many medical words are there in a medium-sized medical dictionary? The answer is around 100,000, which is only a conservative estimate. Moreover, like the jargon（行话）in all forward-moving fields, the number is expanding so constantly and quickly that it defies 藐视any memorization!Most medical terms are based on Greek and Latinwords, which are consistent 一致的and uniform 统一的throughout manydifferent areas. These Greek and Latin parts of words are called the root, prefix, suffix, combing vowels and combining forms.The root, prefix, suffix can aid in learning and remembering medical terms and even help in making informed guesses as to the meaning of unfamiliar words.Furthermore, their numbers are limited, about 400 to 500 or so (the most active ones), but the combinations derived from them are enormous. From what has been discussed above, we may reasonablyreach the conclusion that to learn the root, prefix, suffix is much more efficient and meaningful than to try to memorize every medical term.•• adeno-腺• angio- 血管• arterio－动脉• arthro-关节• atrio-心房;
