Notes for the graphics build
- No molecular structure (PDB) was needed for this page; the molecular-cascade graphic uses a real SEM plus a clearly labeled schematic of proposed signalling routes.
- The small-intestine figure mixes a labeled diagram (panel a) with real micrographs (panels b–d); the on-graphic caption says so explicitly.
