Quantitative studies on the contiguity of muscle fibre types in normal and hypertrophic skeletal muscles.
Skeletal muscles consist of an heterogeneous population of muscle fibres. A method for deriving an index of contiguity for any of the fibre types is proposed. This term is defined as the proportion of the total boundary length (interface) of a fibre type which is in contact with fibres of the same type. It can be measured on any type of skeletal muscle independently of its composition. Values for the index of contiguity for the two major types of fibre in normal and hypertrophic extensor digitorum longus muscles of the mouse do not seem to differ.
