Figures 8-11 in The adductor pectoral fin muscle of Micropogonias furnieri (Perciformes: Sciaenidae): a morphological and histochemical study

Figures 8-11. Histochemical staining of mATPase activity in the adductor fin muscle of Micropogonias furnieri. (8). mATPase activity with pre-incubation at pH 10.4 showing red and pink fibers; small and medium fibers lose their activity; large fibers show a strong reaction (lp: large pink, lr: large red, mp: medium pink, mr: medium red, sp: small pink, sr: small red), (bar = 100 µm). (9). mATPase activity with pre-incubation at pH 10.4. A homogeneous staining of white fibers of the proximal zone is shown (lp: large pink, lwp: large white proximal, mp: medium pink, mwp: medium white proximal, sp: small pink, swp: small white proximal), (bar = 120 µm). (10). mATPase activity with pre-incubation at pH 4.3; white fibers of the proximal zone showing a mosaic pattern of staining (lwp: large white proximal, mwp: medium white proximal, p: pink, swp: small white proximal), (bar = 120 µm). (11). mATPase with pre-incubation at pH 4.3 showing white fibers of distal zone; small white fibers (swd) exhibit a strong reaction; medium (mwd) and large (lwd) fibers show a moderate reaction, (bar = 80 µm).
