Free Medical Terminology Questions and Answers — Questions and Answers
Question 1: Which of the following best describes the overall meaning of "corpus"?
- Body (Correct answer)
- Chest
- Head
- Abdomen
Correct answer: Body
The Latin root 'corpus' directly translates to 'body.' In medical terminology, it is frequently used to refer to the main part or body of an organ or structure. Examples include the corpus callosum (body of the callosum) or corpus luteum (yellow body), consistently denoting the principal mass or structure.
Question 2: Which of the following describes a white blood cell count that is abnormally low?
- Leukocytosis
- Leukopenia (Correct answer)
- Anemia
- Leukemia
Correct answer: Leukopenia
Leukopenia is the correct medical term for an abnormally low white blood cell (leukocyte) count. The prefix 'leuko-' refers to white, and the suffix '-penia' means deficiency or abnormally low. In contrast, leukocytosis indicates an abnormally high white blood cell count, anemia is a deficiency of red blood cells, and leukemia is a type of cancer affecting blood and bone marrow.
Question 3: Which of the following best describes a region of dead cardiac tissue?
- Hypertrophy
- An induration
- An infarct (Correct answer)
- Angina pectoris
Correct answer: An infarct
An infarct is a localized area of dead tissue that results from a lack of blood supply, a condition known as ischemia. In the context of cardiac tissue, a myocardial infarct (heart attack) specifically refers to an area of heart muscle that has died due to blocked blood flow. Other options describe different conditions: hypertrophy is enlargement, induration is hardening, and angina pectoris is chest pain due to reduced blood flow, not dead tissue.
Question 4: Which of the following best describes the term "lithiasis"?
- Penetrating a cavity
- Constriction of tissue
- Dissolving
- Abnormal condition of stones (Correct answer)
Correct answer: Abnormal condition of stones
The suffix '-lithiasis' in medical terminology consistently refers to the formation or presence of stones (calculi) within the body. This term describes an abnormal condition where these concretions are present, such as in cholelithiasis (gallstones) or nephrolithiasis (kidney stones). It specifically denotes the pathological presence of stones.
Question 5: Which of the following is the menarche?
- End of childhood
- End of pregnancy
- Beginning of menstruation (Correct answer)
- Development of female characteristics
Correct answer: Beginning of menstruation
Menarche specifically refers to the first menstrual period a female experiences, marking the onset of puberty and reproductive capability. It is a key physiological milestone in female development, distinct from the broader development of secondary sexual characteristics or the end of childhood. This term precisely defines the beginning of menstruation.
Question 6: Which substance makes up adipose tissue?
- Skin
- Fat cells (Correct answer)
- Lymph nodes
- Muscles
Correct answer: Fat cells
Adipose tissue is a specialized connective tissue primarily composed of adipocytes, which are fat cells. These cells are designed to store energy in the form of lipids, provide insulation, and cushion organs. While other tissues may contain some fat, adipose tissue is defined by its predominant cellular component being fat cells.
Question 7: Which of the following expressions describes the restriction of comfortable breathing to upright postures?
- Orthopnea (Correct answer)
- Apnea
- Dyspnea
- Eupnea
Correct answer: Orthopnea
Orthopnea is a specific type of dyspnea (shortness of breath) that occurs when lying flat, forcing the person to sit or stand up to breathe comfortably. This symptom is often associated with conditions like congestive heart failure, where fluid accumulates in the lungs more easily in a supine position. Apnea is the cessation of breathing, dyspnea is general difficulty breathing, and eupnea is normal breathing.
