Question

question 7
the surgical technique that brings a new blood supply to heart muscles by detouring around blocked atherosclerotic coronary arteries is called a(n):
coronary artery bypass
cardiac tuning
venal bypass
mitral commissurotomy

question 8
the surgical term phalang/ectomy means:
excision of a finger or toe bone
excision of the patella
surgical repair of the tendon and muscle
excision of the meniscus

question 9
cerebrum means:
nerve
axon
skull
brain

Explanation:

• Question 7: Coronary artery bypass is a well - known surgical procedure where a new path (bypass) is created around blocked coronary arteries to supply blood to the heart muscles. Cardiac tuning is not a standard surgical term in this context. Venal bypass is not relevant to the coronary arteries of the heart. Mitral commissurotomy is a procedure related to the mitral valve, not the coronary arteries.
• Question 8: The root word "phalang" refers to the bones of the fingers or toes (phalanges). "Ectomy" means excision. So, phalang/ectomy means excision of a finger or toe bone. The patella is the kneecap (the root for patella is "patell - "), tendon and muscle repair would have roots related to tendon (e.g., "tendin - ") and muscle (e.g., "myo - "), and the meniscus has the root "menisc - ".
• Question 9: Cerebrum is a part of the brain. A nerve is a different structure (root words like "neur - " are related to nerves). An axon is a part of a nerve cell. The skull is the bony structure that houses the brain (root words like "cranio - " are related to the skull).

Answer:

• Question 7: coronary artery bypass
• Question 8: excision of a finger or toe bone
• Question 9: brain
