Abstract: 
Cytological differentiations of the cephalic aorta of Sepia officinalis L. were analysed by LM and TEM. The origin and ultrastructure of the elastic fibres are demonstrated. The highly specialised cross striated muscle cells of the T. media with their particular Z-patch system and close interdigitations with extended areas of gap junctions represent a functional syncytium. Only the peripheral layer of muscle cells of the T.m. is innervated. The histo- und immunhistochemical findings confirm earlier pharmacological results suggesting that the vessel tonus is under a multiple, i.e. cholin-, catecholamin- and peptidergic neurocontrol. The role of 5-HT as a putative neurotransmitter in this mechanism is not yet clarified.
