The coronal veins form what plexuses along the side of the collateral cartilages?

• A. Arterial arches
• B. Venous plexeses
• C. Circumflex arteries
• D. Paracuneal arteries

Answer: (C)

The key idea here is that veins can form networks called venous plexuses along cartilaginous structures. The coronal (or coronary) veins run along the sides of the collateral nasal cartilages and organize into a venous plexus to collect blood from the nose and nearby tissues, draining into the facial venous system. This is about a venous network, not arteries, so terms describing arterial structures—such as circumflex arteries or arterial arches—don’t fit. The correct concept is the formation of venous plexuses along the collateral cartilages.
