CMI Visual Communication & Design Principles 2

Question 1

In medical illustration, which Gestalt principle explains why viewers perceive a series of dashed lines as a continuous contour?

Accepted Answer

Continuity

Answer

The Gestalt principle of continuity causes the eye to follow a path even when interrupted, perceiving dashes as a single flowing line.

Question 2

A medical illustrator uses a cool blue background with a warm orange organ highlighted at center. This technique primarily exploits which design concept?

Accepted Answer

Simultaneous contrast

Answer

Simultaneous contrast intensifies the perceived difference between complementary hues placed adjacent to each other, making the orange organ pop against blue.

Question 3

When depicting a cross-sectional view of the spinal cord, which line weight convention best distinguishes the outermost boundary from internal structures?

Accepted Answer

Heaviest line on the outer contour, progressively lighter lines internally

Answer

A hierarchy of line weights with the heaviest on the outer silhouette and lighter lines inside creates depth and readable layering in cross-sections.

Question 4

Which typography rule is most critical when labeling anatomical structures on a complex surgical illustration?

Accepted Answer

Maintain consistent type size and weight to avoid creating unintended visual hierarchy

Answer

Consistent label type size and weight prevents accidental emphasis on less-important structures and preserves the intended visual hierarchy of the image.

Question 5

A two-page spread in a medical atlas uses a full bleed illustration on the left and text on the right. What design principle governs the gutter margin to prevent content loss during binding?

Accepted Answer

Safe zone / gutter margin compensation

Answer

A safe zone or increased gutter margin ensures critical visual content is not swallowed by the binding when the pages are folded and trimmed.
