✦ Synopsis

Serial transverse paraffin sections of intrafusal muscle fibers of spindles from the extensor pollicis and the extensor digitorum communis of ducks show that only one type of intrafusal muscle fiber exists, based on the mid-equatorial nucleation pattern, diameter, and length. Although the overall range in fiber diameter at the mid-equatorial region is between 4.2-20.0 pm, the average caliber is 10.4 f 3.18 pm (S.D.) for spindles of the extensor pollicis and 9.3 f 2.11 pm (S.D.) for spindles of the extensor digitorum communis muscles. The range in spindle length for the extensor pollicis is 290-2,090 pm, average 1,120 f 569 pm (S.D.), and for the extensor digitorum communis 1,160-2,500 pm, average 1,745 367 pm (S.D.). The range in number of fibers

Distributions of motor axons to different types of intrafusal fiber were reconstructed from serial 1-micron thick transverse sections of six poles of muscle spindle in the rat soleus. Motor axons innervated (dynamic) bag1 fibers, or (static) bag2 fibers in conjunction with chain fibers. However, app

A cat tenuissimus muscle spindle that contained two long chain intrafusal fibers in its distal pole is described. One of the fibers (lc1) had a histochemical profile (ATPase, NADH-TR, ChE reactions) of the kind which is characteristic for long chain fibers. The other fiber (lc2) consisted of two sep
