Description

Transmission electron micrograph of rat sartorius striated muscle showing the regular arrangement of the actin-myosin myofilaments and abundant mitochondria. This 1956 TEM image has historical value as one of the earliest views of muscle ultrastructure. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.
