title: [Ultrastructural changes of human skeletal muscle after tendon and nerve injuries. II. Fine-structural alterations of the hand muscles after injuries of the motor nerve (author's transl)].
abstract: The authors examined the fine structural alterations of the muscles after traumatic neurotomy. The most important changes were forro found on the contractile elements, especially atrophy, and fragmentation. The number of mitochondria and sarcoplasmatic reticulum decreased both the glycogen content of sarcoplasma increased. The motor end plates were complete destroyed. On the motor motor-neurons typical Wallerian degeneration could be seen.
