The Evolution of the Mitochondria-to-Calcium Release Units Relationship in Vertebrate Skeletal Muscles

<table>Higher magnifications highlighting association of mitochondria and SR (a)–(c). Tethering connections anchor mitochondria to the jSR of the triads (CRUs) in images of mouse EDL ((a) and (c), white arrows). Similar tethers (white arrows) anchor mitochondria to the longitudinal SR, not necessarily to CRUs, in the leg muscle from a finch (b).</table>
