The Evolution of the Mitochondria-to-Calcium Release Units Relationship in Vertebrate Skeletal Muscles
Figure 6
Cross-sections of small fibers in zebrafish. These images illustrate two characteristics of mitochondria (m) disposition in fish muscles. There is a tendency for clustering of the organelles in small groups that are mostly segregated to the fibers’ edges. In this manner, proximity of the mitochondrion’ surface to CRUs is quite limited.
