Med test
We’re going to get you ready for your MED101 Medical Terminology test! ❤ Since your test is tomorrow at St. Clair College, I’ve organized a study guide for Chapters 1, 2, 3, 4, 6, and 10, including the abdominal quadrants (RUQ, LUQ, RLQ, LLQ) and the diagrams you need to practise.
This guide covers the important introductory material for these topics. Your professor’s review slides are the best source for the exact terms and diagrams that will be tested.
MED101 — Test 1 complete study guide
Chapter 1: Word roots and combining forms
Medical words are built from smaller parts.
Prefix + Word root + Suffix
A medical word can contain any combination of these parts.
Prefix
Beginning of a word
hyper-
Word root
Main meaning
cardi
Suffix
End of a word
-ia
Example: hyper/therm/ia refers to a condition of excessive heat or high temperature.
The three terms you must understand
Word root: the main part of a word that gives its basic meaning. Example: cardi = heart.
Combining vowel: usually o, used to make medical words easier to pronounce.
Combining form: a word root plus a combining vowel. Example: cardi/o = heart.
Important word roots
Word root or combining form | Meaning |
cardi/o | Heart |
neur/o | Nerve |
oste/o | Bone |
my/o | Muscle |
arthr/o | Joint |
gastr/o | Stomach |
enter/o | Intestine |
hepat/o | Liver |
hemat/o | Blood |
derm/o | Skin |
pneum/o | Lung or air |
cephal/o | Head |
rhin/o | Nose |
ot/o | Ear |
ophthalm/o | Eye |
nephr/o | Kidney |
cyst/o | Bladder or sac |
cyt/o | Cell |
hist/o | Tissue |
path/o | Disease |
Combining rules
A combining vowel is often used when joining two word roots: oste/o/arthr/itis.
The combining vowel is usually kept between a root and a suffix that starts with a consonant: cardi/o/logy.
The combining vowel is usually dropped before a suffix that starts with a vowel: gastr/itis.
These are common patterns; your course’s specific examples should take priority.
Chapters 2 and 3: Prefixes and suffixes
A prefix goes at the beginning of a word. A suffix goes at the end.
Prefixes to memorize
Prefix | Meaning | Example |
a-, an- | Without, not | Aseptic = without contamination by disease-causing microorganisms |
hyper- | High, excessive | Hypertension = high blood pressure |
hypo- | Low, below normal | Hypoglycemia = low blood sugar |
brady- | Slow | Bradycardia = slow heart rate |
tachy- | Fast | Tachycardia = fast heart rate |
peri- | Around | Pericardium = membrane around the heart |
endo- | Within | Endoscopy = examination inside the body |
epi- | Upon, on | Epidermis = outer layer of skin |
intra- | Within | Intravenous = within a vein |
inter- | Between | Intercostal = between the ribs |
sub- | Under, below | Subcutaneous = under the skin |
pre- | Before | Prenatal = before birth |
post- | After | Postoperative = after surgery |
uni- | One | Unilateral = one-sided |
bi- | Two | Bilateral = two-sided |
poly- | Many, much | Polyuria = excessive urination |
Suffixes to memorize
Suffix | Meaning | Example |
-itis | Inflammation | Arthritis |
-algia | Pain | Myalgia |
-ectomy | Surgical removal | Appendectomy |
-ology | Study of | Hematology |
-ologist | Specialist who studies or treats | Cardiologist |
-oma | Tumour or mass | Hematoma |
-pathy | Disease | Neuropathy |
-emia | Blood condition | Anemia |
-megaly | Enlargement | Cardiomegaly |
-scopy | Visual examination | Endoscopy |
-gram | Record or image | Electrocardiogram |
-graphy | Process of recording or imaging | Angiography |
-plasty | Surgical repair | Rhinoplasty |
-rrhea | Flow or discharge | Diarrhea |
-uria | Urine condition | Hematuria |
-penia | Deficiency or decrease | Leukopenia |
-cyte | Cell | Erythrocyte |
-osis | Condition, often abnormal | Cyanosis |
Test tip: If you see -itis, think inflammation. If you see -ectomy, think surgical removal. If you see -algia, think pain.
Chapter 4: Human body orientation
This is especially important because you mentioned diagrams.
1. Directional terms
Term | Meaning |
Superior | Above; toward the head |
Inferior | Below; toward the feet |
Anterior | Front |
Posterior | Back |
Medial | Toward the body’s midline |
Lateral | Away from the midline |
Proximal | Closer to the limb’s point of attachment |
Distal | Farther from the limb’s point of attachment |
Superficial | Near the surface |
Deep | Farther inside the body |
Ipsilateral | Same side |
Contralateral | Opposite sides |
Examples:
The head is superior to the chest.
The stomach is inferior to the heart.
The nose is medial to the eyes.
The ears are lateral to the eyes.
The elbow is proximal to the wrist.
The skin is superficial to the muscles.
2. Anatomical position
Know the standard anatomical position:
Standing upright.
Head and eyes facing forward.
Arms at the sides.
Palms facing forward.
Feet pointing forward.
Body directions are described using this position as the reference, even when a person is sitting or lying down.
3. Body planes
Plane | What it divides |
Sagittal | Left and right |
Midsagittal | Equal left and right halves |
Frontal (coronal) | Front and back |
Transverse (horizontal) | Upper and lower |
Oblique | At an angle |
Remember: sagittal = sides, frontal = front/back, transverse = top/bottom.
4. Body cavities
Cavity | What it contains or protects |
Cranial | Brain |
Vertebral (spinal) | Spinal cord |
Thoracic | Heart and lungs |
Abdominal | Many digestive organs |
Pelvic | Bladder, internal reproductive organs, and rectum |
The dorsal cavity includes the cranial and vertebral cavities. The ventral cavity includes the thoracic and abdominopelvic cavities.
5. The four abdominal quadrants
Abbreviation | Full name | Examples of organs found there |
RUQ | Right Upper Quadrant | Liver, gallbladder, part of right kidney |
LUQ | Left Upper Quadrant | Stomach, spleen, part of left kidney |
RLQ | Right Lower Quadrant | Appendix, parts of the intestines |
LLQ | Left Lower Quadrant | Parts of the large intestine |
Very important: The patient’s right and left are opposite yours when you face the patient.
RUQ = patient’s upper right.
LUQ = patient’s upper left.
RLQ = patient’s lower right.
LLQ = patient’s lower left.
You should be able to label all four on a blank diagram.
Chapter 6: Musculoskeletal system

Chapter 10: Blood system
1. The four main blood components
Component | Main job |
Red blood cells (erythrocytes) | Carry oxygen using hemoglobin |
White blood cells (leukocytes) | Help defend against infections |
Platelets (thrombocytes) | Help blood clot |
Plasma | Liquid that transports blood cells and dissolved substances |
2. Blood-related word roots
Word part | Meaning |
hemat/o | Blood |
hem/o | Blood |
erythr/o | Red |
leuk/o | White |
thromb/o | Clot or platelet |
cyt/o | Cell |
phleb/o | Vein |
ven/o | Vein |
arteri/o | Artery |
coagul/o | Clotting |
3. Important blood terminology
Term | Meaning |
Hematology | Study of blood |
Erythrocyte | Red blood cell |
Leukocyte | White blood cell |
Thrombocyte | Platelet |
Anemia | Reduced oxygen-carrying capacity of blood, often due to low hemoglobin or red blood cells |
Leukocytosis | Increased white blood cell count |
Leukopenia | Decreased white blood cell count |
Hematoma | Collection of blood outside blood vessels |
Hemostasis | Process of stopping bleeding |
Coagulation | Blood-clotting process |
Hematuria | Blood in the urine |
4. Blood vessels
Arteries: carry blood away from the heart.
Veins: carry blood toward the heart.
Capillaries: tiny vessels where substances are exchanged between blood and tissues.
Remember: arteries and veins are named by the direction blood travels, not simply by whether the blood contains oxygen.

Final test tips
Memorize the meaning of the prefixes and suffixes, not just the examples.
Practise labeling diagrams without looking at the answers.
Learn the difference between similar terms, especially tendon vs. ligament, proximal vs. distal, and anterior vs. posterior.
Practise spelling medical terms correctly.
Review your professor’s slides because they may include specific terms that aren’t in this general guide.
