Abstract

A direct correlation of the histochemical and ultrastructural properties of intrafusal muscle fibres has been achieved by cutting frozen serial sections for histochemical applications (15 micron thick sections) and for electron microscopy (60 micron thick sections) in a repeating sequence. Three types of intrafusal fibre were recognized, including two types of nuclear-bag fibre, designated bag1 and bag2. In addition to histochemical and ultrastructural differences, the three types of fibre differed in length and diameter. Regional variations of histochemical and ultrastructural properties were found. The results are compared with previous attempts to correlate histochemical and ultrastructural properties of intrafusal muscle fibres based on indirect methods.
