Examples of semi-thin (1-μm-thick) transverse sections through the polar (left) and equatorial (right) regions of a cat tenuissimus spindle, serially sectioned throughout its length. The polar-region section passes through a motor ending on a chain fibre, and the equatorial-region section passes through the primary ending, which is reconstructed in Figs1 and 2. Toluidine blue; width of each image is 85 μm.
