Overview of Medical Terminology
Medical terminology is a specialized language used by healthcare providers to describe the human body, its functions, conditions, procedures, and treatments precisely and efficiently. Its structure often involves roots, prefixes, and suffixes that combine to form meaningful terms.
Importance of Learning Medical Terminology
- Facilitates clear communication among healthcare professionals
- Ensures accurate documentation and billing
- Aids in understanding patient diagnoses and treatment plans
- Enhances your professional credibility and confidence
Components of Medical Terminology
- Root Words: Basic meaning of the term (e.g., cardi- refers to the heart)
- Prefixes: Added to the beginning to modify meaning (e.g., hyper- means excessive)
- Suffixes: Added to the end to specify condition, procedure, or anatomy (e.g., -itis indicates inflammation)

- Hepatitis: Liver inflammation
- Gastritis: Stomach inflammation
- Dysphagia: Difficulty swallowing
- Enteritis: Intestinal inflammation
Prefixes/Suffixes:
- Gastro- (stomach), -itis (inflammation)
4. The Nervous System
Includes the brain, spinal cord, and nerves.
Common Terms:
- Neurology: Study of the nervous system
- Encephalitis: Brain inflammation
- Neuralgia: Nerve pain
- Stroke: Disruption of blood flow to the brain
- Seizure: Sudden abnormal electrical activity in the brain
Prefixes/Suffixes:
- Neur- (nerve), -algia (pain)
5. The Musculoskeletal System
Consists of bones, muscles, joints, and connective tissue.
Common Terms:
- Orthopedics: Study of bones and muscles
- Arthritis: Joint inflammation
- Osteoporosis: Bone loss
- Myalgia: Muscle pain
- Fracture: Broken bone
Prefixes/Suffixes:
- Osteo- (bone), -itis (inflammation)

Understanding Prefixes, Suffixes, and Roots
A solid grasp of common prefixes, suffixes, and roots is crucial for decoding unfamiliar medical terms.
Common Prefixes
- a- / an-: Without, not (e.g., anemia — lack of blood)
- Brady-: Slow (e.g., bradycardia — slow heart rate)
- Tachy-: Fast (e.g., tachypnea — rapid breathing)
- Hyper-: Excessive (e.g., hypertension — high blood pressure)
- Hypo-: Deficient, below normal (e.g., hypoglycemia — low blood sugar)
Common Suffixes
- -itis: Inflammation (e.g., gastritis)
- -osis: Condition, usually abnormal or diseased (e.g., neurosis)
- -ectomy: Surgical removal (e.g., appendectomy)
- -algia: Pain (e.g., neuralgia)
- -cyte: Cell (e.g., erythrocyte)
Common Roots
- Cardi-: Heart
- Pulmon-: Lung
- Gastr-: Stomach
- Neur-: Nerve
- Oste-: Bone

Practice and Application of Medical Terms
Applying knowledge through practice is vital for mastery. Here are some strategies:
Techniques for Learning Medical Terminology
- Flashcards: Create flashcards for prefixes, suffixes, and roots
- Word Breakdown: Practice dissecting complex terms into parts
- Use in Context: Write sentences or case scenarios using new terms
- Quizzes and Tests: Regular self-assessment to reinforce memory
Sample Exercises
1. Break down the term osteomyelitis:
- Osteo- (bone) + -myel- (marrow/spinal cord) + -itis (inflammation)
2. Identify the body system related to neurosurgery:
- Nervous system
3. Define hyperglycemia:
- Excessive blood sugar
