Figures 4-7 in The adductor pectoral fin muscle of Micropogonias furnieri (Perciformes: Sciaenidae): a morphological and histochemical study

Figures 4-7. Histochemical staining of red, pink and white fibers from the adductor fin muscle of Micropogonias furnieri. (4). Red fibers showing strong staining (SDH technique); pink fibers showing weak reaction to SDH (lp: large pink, lr: large red, mp: medium pink, mr: medium red, sp: small pink, sr: small red), (bar = 100 µm). (5). Periodic acid-Schiff (PAS) showing small red fibers (sr) with very strong stain intensity, and small pink (sp) fibers with moderate activity; medium and large fibers react weakly to PAS (lp: large pink, lr: large red, mp: medium pink, mr: medium red), (bar = 50 µm). (6). The small (swp) and medium (mwp) white fibers of the proximal zone show a weak reaction to SDH; large fibers (lwp) have no reaction, (bar = 100 µm). (7). White fibers of the proximal zone react weakly to PAS; white fibers of the distal zone have no reaction (lwd: large white distal, lwp: large white proximal, mwd: medium white distal, mwp: medium white proximal, swd: small white distal, swp: small white proximal), (bar = 150 µm).
