When recovery takes place the affected fibre is believed to be regenerated by a cell-growth within the sarcolemma.
They have no sarcolemma, stripes, or cross markings like those of the voluntary muscles.
The muscular fibrils were friable and granular, and there was multiplication of the nuclei of the sarcolemma.
Each fiber is enclosed within a delicate, transparent sheath, known as the sarcolemma.
In the first variety the transverse stri disappear and the sarcolemma appears filled with finely granular matter.
sarcolemma: the elastic covering of the striated muscular fibres.
