Abstract

As is known, the skeletal musculature of the frog consists of two types of muscle fibres differing both functionally and morphologically; they are: rapid ‘non-tonic’ fibres which are innervated by thick nerve fibres and slow ‘tonic’ fibres which are innervated by thin nerve fibres. The basic functional destruction of the tonic muscle fibres from the ‘non-tonic’ muscles is their capacity to produce contractures.
