Fig. 2. Transmission electron micrographs of longitudinal sections of the transverse muscle fibres of the tentacle (A) and arm (B) of Loligo pealei. The extensive sarcoplasmic reticulum (SR) of the cross-striated tentacle fibres is visible. Note the short sarcomeres and short thick filaments of the tentacle fibres compared with the much longer thick filaments apparent in the obliquely striated arm fibres. Scale bar, 1 µm.
