What diameter range is typical of a muscular artery?
AFrom 0.01 mm to 1 mm
BFrom 0.1 mm to 10 mm
CFrom 1 mm to 100 mm
DFrom 10 mm to 100 mm
Answer & Solution
Correct answer: B. From 0.1 mm to 10 mm
1. Further from the heart the elastic fiber content of an artery falls and its smooth muscle rises.
2. Such a vessel is a muscular artery, and its diameter typically runs from 0.1 mm to 10 mm.
3. The upper bound of 10 mm is the same figure that marks the start of the elastic artery range.
4. Values in the 100 mm range exceed the diameter of any systemic artery, so those options fail on scale alone.
