Questions & Answers from this book
Questions and answers are connected to the referenced book and its available source material.
Chapter 1: Introduction to Medical Terminology
What is the difference between a sign and a symptom in medical terminology?
A sign is an objective indication of a medical condition that can be observed by a healthcare professional, while a symptom is a subjective experience reported by the patient, indicating how they feel.
What does the suffix '-rrhagia' refer to in medical terminology?
The suffix '-rrhagia' refers to excessive bleeding or hemorrhage in medical terminology.
Chapter 2: The Human Body in Health and Disease
What is the difference between adenoma and adenocarcinoma as described in the chapter?
Adenoma is a benign tumor that arises in or resembles glandular tissue, while adenocarcinoma is a malignant tumor that originates in glandular tissue. The key difference lies in their nature, with adenomas being non-cancerous and adenocarcinomas being cancerous and potentially life-threatening.
What are some examples of genetic disorders mentioned in the chapter, and how do they manifest?
Examples of genetic disorders include cystic fibrosis, Down syndrome, hemophilia, Huntington's disease, muscular dystrophy, and phenylketonuria (PKU). These disorders can manifest in various ways, such as respiratory and digestive issues in cystic fibrosis, characteristic facial features and developmental delays in Down syndrome, and nerve degeneration in Huntington's disease.
What is the difference between the parietal peritoneum and the visceral peritoneum?
The parietal peritoneum is the outer layer that lines the interior of the abdominal wall, while the visceral peritoneum is the inner layer that surrounds the organs within the abdominal cavity.
Chapter 3: The Skeletal System
What is the primary function of red bone marrow as described in the chapter on the skeletal system?
The primary function of red bone marrow is to help form red blood cells.
How do ligaments function in the skeletal system according to the text?
Ligaments function in the skeletal system by connecting one bone to another, forming joints. They are made of fibrous tissue and allow for movement in various directions, particularly in complex joints like the knee.
What are the major structures of the skeletal system as outlined in the chapter?
The major structures of the skeletal system include bones, bone marrow, cartilage, joints, ligaments, synovial membranes, synovial fluid, and bursae.
Chapter 4: The Muscular System
What is a Colles’ fracture and how does it occur according to the chapter?
A Colles’ fracture, also known as a fractured wrist, occurs at the lower end of the radius when a person tries to stop a fall by landing on their hands. This type of fracture is commonly associated with the impact of a fall, particularly in individuals with weakened bones due to osteoporosis.
What is the difference between osteoporosis and osteopenia as described in the chapter?
Osteoporosis is characterized by a significant loss of bone density and increased bone porosity, often associated with aging. Osteopenia, on the other hand, indicates thinner-than-average bone density and serves as a warning sign for potential future development of osteoporosis.
What is the difference between arthrodesis and arthrolysis in joint surgery?
Arthrodesis is the surgical fusion of two bones to stiffen a joint, while arthrolysis is the surgical loosening of an ankylosed joint. Arthrodesis is typically used to treat severe arthritis or a damaged joint, whereas arthrolysis aims to restore movement to a joint that has become stiff due to fusion.
Chapter 10: The Nervous System and Mental Health
How do osteopenia and osteoporosis differ based on their word parts?
Osteopenia and osteoporosis differ in their word parts primarily through the prefixes used. 'Osteopenia' includes 'penia,' which means deficiency, indicating a lower than normal bone density. In contrast, 'osteoporosis' uses 'porosis,' meaning porous, which refers to a condition where bones become more porous and fragile due to significant loss of bone density.
Why might Dr. Johnstone consider internal fixation over total hip replacement for Mrs. Gwynn's treatment?
Dr. Johnstone might consider internal fixation over total hip replacement for Mrs. Gwynn because she is a frail 85-year-old with severe osteoporosis. Internal fixation would repair her femoral neck fracture but not improve her mobility, which is less critical given her condition. Additionally, this option has a shorter recovery time, is less expensive, and involves a less strenuous recovery period compared to total hip replacement.
