title: Fine structure of single fibres of human skeletal muscle.
abstract: Individual muscle fibres were separated from freeze-dried needle biopsies and classed as type I or type II fibres according to their myofibrillar ATP-ase. Portions of the same fibres were processed for electron microscopy and their fine structure examined. Type I fibres were found to have thicker Z-bands and more mitochondria and lipid droplets than the type II fibres.
