MT Medical Terminology & Anatomy 1 — Questions and Answers
Question 1: What does the prefix 'brady-' mean in medical terminology?
- Fast
- Slow (Correct answer)
- Normal
- Irregular
Correct answer: Slow
In medical terminology, the prefix 'brady-' consistently indicates slowness or a slow rate. For example, 'bradycardia' refers to a slow heart rate, and 'bradypnea' means slow breathing. Understanding this prefix is crucial for interpreting many medical terms.
Question 2: What is the term for inflammation of the liver?
- Nephritis
- Hepatitis (Correct answer)
- Arthritis
- Dermatitis
Correct answer: Hepatitis
The term 'hepatitis' is derived from the Greek word 'hepar' meaning liver, and the suffix '-itis' which denotes inflammation. Therefore, 'hepatitis' specifically refers to the inflammation of the liver. This condition can be caused by various factors, including viral infections, alcohol, and certain medications.
Question 3: Which body system includes the heart and blood vessels?
- Digestive system
- Cardiovascular system (Correct answer)
- Respiratory system
- Muscular system
Correct answer: Cardiovascular system
The cardiovascular system, also known as the circulatory system, is responsible for circulating blood throughout the body. It consists of the heart, which pumps blood, and a network of blood vessels (arteries, veins, and capillaries) that transport oxygen, nutrients, hormones, and waste products. This system is vital for maintaining overall bodily functions.
Question 4: What does 'osteoporosis' refer to?
- Muscle growth
- Bone weakening (Correct answer)
- Joint inflammation
- Skin infection
Correct answer: Bone weakening
Osteoporosis is a medical condition characterized by the weakening and thinning of bones, making them fragile and more susceptible to fractures. The term literally means "porous bone," reflecting the loss of bone density. This condition often develops silently over many years and is common in older adults, particularly postmenopausal women.
Question 5: Which of the following terms means 'surgical removal of the stomach'?
- Cholecystectomy
- Gastrectomy (Correct answer)
- Appendectomy
- Nephrectomy
Correct answer: Gastrectomy
In medical terminology, the suffix '-ectomy' means surgical removal. The prefix 'gastr-' refers to the stomach. Therefore, 'gastrectomy' precisely means the surgical removal of all or part of the stomach.
Question 6: What is the meaning of the term 'cyanosis'?
- Red skin
- Bluish skin (Correct answer)
- Yellow skin
- Pale skin
Correct answer: Bluish skin
Cyanosis is a medical sign characterized by a bluish discoloration of the skin and mucous membranes. This occurs due to a lack of oxygen in the blood, specifically an increased concentration of deoxygenated hemoglobin. It often indicates an underlying issue with the circulatory or respiratory system.
Question 7: Which anatomical term refers to the back side of the body?
- Ventral
- Dorsal (Correct answer)
- Superior
- Inferior
Correct answer: Dorsal
In anatomical terms, 'dorsal' refers to the back or posterior side of the body or a body part. For instance, the dorsal fin of a fish is on its back, and the dorsal surface of the hand is the back of the hand. Conversely, 'ventral' refers to the front or anterior side.
Question 8: What is the primary function of red blood cells?
- Fight infection
- Carry oxygen (Correct answer)
- Form blood clots
- Regulate body temperature
Correct answer: Carry oxygen
The primary function of red blood cells (erythrocytes) is to transport oxygen from the lungs to the body's tissues and to carry carbon dioxide back to the lungs to be exhaled. They contain a protein called hemoglobin, which binds to oxygen, enabling this vital gas exchange. This process is essential for cellular respiration and overall bodily function.
Question 9: Which term refers to the windpipe?
- Bronchi
- Esophagus
- Trachea (Correct answer)
- Alveoli
Correct answer: Trachea
The trachea, commonly known as the windpipe, is a cartilaginous tube that connects the larynx (voice box) to the bronchi of the lungs. Its main function is to provide a clear airway for air to enter and exit the lungs. It is a crucial component of the respiratory system.
