Why Does the Golgi Apparatus Have Two Faces?
The Golgi apparatus receives cargo at its cis side and helps sort processed cargo at its trans side. The stacked sacs have membranes surrounding internal spaces called lumens.

What the illustration shows
English navy-and-gold poster titled Why Does the Golgi Apparatus Have Two Faces? A dimensional gold-peach stack of flattened membrane sacs has an incoming blue ER-derived carrier at upper left, with a cyan arrow toward the cis face. Purple arrows leave the lower trans face toward two outgoing carriers. Labels identify Golgi cisternae and both faces. A lower inset cuts one cisterna open to distinguish its enclosing membrane from the lumen. Text presents a directional overview and states that not all cargo is secreted. Gold AllHumanBody.com and full slogan sit on plain navy.
How to interpret this poster
- Directional overview, not a literal conveyor, fixed cisterna count or universal cell orientation; not all cargo is secreted.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
