What is the typical diameter range for muscular arteries?

• A. 0-0.1 mm
• B. 0.1-10 mm
• C. 10-100 mm
• D. 100-1000 mm

Answer: (B)

Muscular arteries are medium-sized vessels with a thick tunica media full of smooth muscle, enabling them to actively regulate blood flow to organs. Their diameter typically falls between 0.1 and 10 millimeters, which places them smaller than elastic arteries like the aorta and larger than arterioles. So the range 0.1–10 mm best fits muscular arteries.
