Neuromuscular junctions and alpha-bungarotoxin-binding sites in denervated and contralateral cat skeletal muscles.

1. The distributions of cholinesterase (ChE) activity and acetylcholine (ACh) receptors were studied in normal and denervated cat hind-limb fast-twitch skeletal muscles and in muscles contralateral to denervated muscles. 2. On normal muscle fibres almost all receptors were confined to the immediately post-junctional membrane, although a perijunctional… CONTINUE READING
