These little knobsform the line of dots which has long been described as existing in themiddle of each bright stripe. When the fibre is somewhat extended this lineappears double, owing to the separation of the heads of the two successive seriesof muscle-rods which meet in the middle of the bright substance. In the state ofabsolute rest (r, Fig. 288) the rods are uniformly cylindrical without terminalenlargements, and in this case only a longitudinal fibrillation is to be seen in thefibre, all trace of transverse striping having disappeared. In the normal stateof slight tension however (p), the rod-heads make their appearance, and with J*.;.
