A prefix usually appears at the beginning of a term, a root provides the central meaning, and a suffix usually appears at the end.\n\n### A. Prefixes \u2014 beginning of a word\n\n| Prefix | Meaning | Example |\n| --- | --- | --- |\n| 1. `hyper-` | Excessive, high | Hypertension |\n| 2. `hypo-` | Below normal, low | Hypoglycemia |\n| 3. `brady-` | Slow | Bradycardia |\n| 4. `tachy-` | Fast | Tachycardia |\n| 5. `a-` / `an-` | Without, not | Apnea |\n\n### B. Roots \u2014 central meaning of a word\n\n| Root | Meaning | Example |\n| --- | --- | --- |\n| 6. `cardi` | Heart | Cardiology |\n| 7. `neur` | Nerve | Neurology |\n| 8. `dermat` | Skin | Dermatology |\n| 9. `gastr` | Stomach | Gastritis |\n| 10. `oste` | Bone | Osteoporosis |\n\n### C. Suffixes \u2014 ending of a word\n\n| Suffix | Meaning | Example |\n| --- | --- | --- |\n| 11. `-itis` | Inflammation | Arthritis |\n| 12. `-ectomy` | Surgical removal | Appendectomy |\n| 13. `-algia` | Pain | Neuralgia |\n| 14. `-logy` | Study of | Cardiology |\n| 15. `-emia` | Blood condition | Anemia |\n\nStudy tip: A combining vowel, usually `o`, often connects a root to another word part. For example, `cardi/o/logy` means the study of the heart.\n\n## Part 2: Practice \u2014 break down and define 10 medical terms\n\nDirections: For each term, identify its prefix, root or combining form, and suffix where applicable. Then write the meaning of the complete term in your own words.\n\n### 1. Hypertension\n\nWord-part guide: hyper- / tens / -ion\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 2. Hypoglycemia\n\nWord-part guide: hypo- / glyc / -emia\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 3. Bradycardia\n\nWord-part guide: brady- / cardi / -ia\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 4. Tachycardia\n\nWord-part guide: tachy- / cardi / -ia\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 5. Apnea\n\nWord-part guide: a- / -pnea\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 6. Neurology\n\nWord-part guide: neur / -logy\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 7. Dermatitis\n\nWord-part guide: dermat / -itis\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 8. Gastralgia\n\nWord-part guide: gastr / -algia\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 9. Osteoporosis\n\nWord-part guide: oste / por / -osis\n\nWord-part breakdown\n\nDefinition in your own words\n\n### 10. Appendectomy\n\nWord-part guide: append / -ectomy\n\nWord-part breakdown\n\nDefinition in your own words\n\nShow hints  Copy responses\n\n## Part 3: Answer key\n\nUse this section after completing the practice activity to check your work.\n\n| # | Word-part breakdown | Definition |\n| --- | --- | --- |\n| 1 | `hyper-` = high; `tens` = pressure; `-ion` = condition | Hypertension: Abnormally high blood pressure. |\n| 2 | `hypo-` = low; `glyc` = sugar; `-emia` = blood condition | Hypoglycemia: Abnormally low blood glucose (blood sugar). |\n| 3 | `brady-` = slow; `cardi` = heart; `-ia` = condition | Bradycardia: A slower-than-normal heart rate. |\n| 4 | `tachy-` = fast; `cardi` = heart; `-ia` = condition | Tachycardia: A faster-than-normal heart rate. |\n| 5 | `a-` = without; `-pnea` = breathing | Apnea: Temporary cessation of breathing. |\n| 6 | `neur` = nerve; `-logy` = study of | Neurology: The medical specialty concerned with the nervous system. |\n| 7 | `dermat` = skin; `-itis` = inflammation | Dermatitis: Inflammation of the skin. |\n| 8 | `gastr` = stomach; `-algia` = pain | Gastralgia: Stomach pain. |\n| 9 | `oste` = bone; `por` = pore or porous; `-osis` = condition | Osteoporosis: A condition in which bones become less dense and more prone to fracture. |\n| 10 | `append` = appendix; `-ectomy` = surgical removal | Appendectomy: Surgical removal of the appendix. |\n\nNote: Some medical terms have historical or modified word forms, so not every part matches a modern English word exactly. For example, `hypertension` is conventionally understood as high blood pressure, and `apnea` uses the breathing element `-pnea`.\n\n## Part 4: Exit ticket\n\nAnswer in one or two sentences.\n\n1. How can knowing word parts help you understand an unfamiliar medical term?\n\n2. What is the difference between the prefixes `hyper-` and `hypo-`?\n\n3. Break down the term arthritis and define it.\n\n### Teacher grading guide\n\n- Part 2: 20 points (1 point for the word-part breakdown and 1 point for the definition per term).\n- Part 4: 6 points (2 points per question).\n- Total: 26 points, plus optional participation credit for using the vocabulary reference."}
