Anatomy and Pathophysiology for Coding Flashcards

The prefix 'hepato-' refers to which organ?

Answer: Liver

The prefix 'hepato-' derives from the Greek 'hepar,' meaning liver, and is used in terms such as hepatomegaly (enlarged liver) and hepatitis (liver inflammation).

A myocardial infarction (MI) occurs when:

Answer: Blood supply to part of the heart muscle is blocked, causing ischemic necrosis

An MI occurs when a coronary artery is blocked (usually by a thrombus), cutting off blood supply to a region of myocardium, causing ischemia and ultimately tissue necrosis.

The suffix '-ectomy' means:

Answer: Surgical removal

The suffix '-ectomy' denotes surgical excision or removal of a structure (e.g., appendectomy = removal of the appendix).

Septicemia involves:

Answer: Pathogenic microorganisms or their toxins in the bloodstream causing systemic infection

The peritoneum is the serous membrane that:

Answer: Lines the abdominal cavity and covers abdominal organs

The peritoneum is the serous membrane lining the abdominal and pelvic cavities and covering most of the abdominal organs; peritonitis is inflammation of this membrane.

In the context of musculoskeletal coding, what is the difference between a sprain and a strain?

Answer: Sprain = ligament injury; strain = muscle/tendon injury

A sprain involves stretching or tearing of a ligament (connecting bone to bone), while a strain involves injury to a muscle or tendon (connecting muscle to bone).
