2. Prefixes: Modifying the Meaning

Prefixes are added to the beginning of a root word to modify its meaning. They can indicate location, number, time, or status. Lesson 1 commonly includes prefixes such as:

• a- or an-: Without, absence of (e.g., apnea - without breathing; anemia - lack of red blood cells)
• hyper-: Excessive, above normal (e.g., hypertension - high blood pressure)
• hypo-: Deficient, below normal (e.g., hypoglycemia - low blood sugar)
• intra-: Within, inside (e.g., intravenous - within a vein)
• inter-: Between (e.g., intercostal - between the ribs)
• sub-: Below, under (e.g., subcutaneous - under the skin)
• super- or supra-: Above, excessive (e.g., superior - above; suprapubic - above the pubic bone)
• peri-: Around (e.g., pericardium - the sac around the heart)
• pre-: Before (e.g., prenatal - before birth)
• post-: After (e.g., postoperative - after surgery)
• bi-: Two (e.g., bilateral - two sides)
• uni- or mono-: One (e.g., unilateral - one side; monocyte - one type of white blood cell)

• tachy-: Fast, rapid (e.g., tachycardia - rapid heart rate)
• brady-: Slow (e.g., bradycardia - slow heart rate)

3. Suffixes: Adding Specificity

Suffixes are attached to the end of a root word to indicate a procedure, condition, or disease. Common suffixes introduced in Lesson 1 include:

• -itis: Inflammation (e.g., appendicitis - inflammation of the appendix)
• -algia: Pain (e.g., neuralgia - nerve pain)
• -oma: Tumor, mass (e.g., carcinoma - cancerous tumor)
• -ectomy: Surgical removal (e.g., appendectomy - surgical removal of the appendix)
• -otomy: Incision, cutting into (e.g., tracheotomy - incision into the trachea)
• -ostomy: Creating an opening (e.g., colostomy - creating an opening in the colon)
• -scopy: Visual examination with an instrument (e.g., endoscopy - visual examination of the inside of the body)
• -graphy: Process of recording (e.g., cardiography - recording of the heart's electrical activity)
• -gram: Record or image (e.g., electrocardiogram - ECG - a recording of the heart's electrical activity)
• -logy: Study of (e.g., cardiology - the study of the heart)
• -ologist: Specialist in the study of (e.g., cardiologist - a heart specialist)

• -uria: Condition of urine (e.g., hematuria - condition of blood in the urine)

4. Combining Forms: Linking Roots and Suffixes

A combining form is a root word with a vowel (usually "o") added to the end. This vowel facilitates the connection between the root word and a suffix or another root word, making the term easier to pronounce. For example, in cardi/o/logy, the "o" in cardi/o is the combining vowel.

5. Anatomical Terms: Directional and Regional

Lesson 1 may also introduce basic anatomical terms related to body directions and regions:

• Superior: Above
• Inferior: Below
