Abstract: 
The pericaryal area of the neurosecretory system of the vena cava (NSV) system of Sepia officinalis is located with serial sections outside the cephalic cartilage approximate 1 mm anteriad of the visceral lobe. It consists of small pericarya with nuclei measuring 3 - 6 mum in diameter. The axons of the visceral nerves are 1 - 8 mum wide, those of the NSV system are 10 - 1600 nm diameter. Surrounded by endoneuria they run side by side up to the vena cava. By staining for neurosecretion Light Green Cells and Yellow Cells could be proved in the NSV system. Acetylcholinesterase is missing in the NSV system but catecholamines were found. Two types of vesicles occur in the pericaryal area: Light dense-cored vesicles with aminergic contents and dark dense-cored vesicles. This type of vesicles indicates the presence of neuropeptides.
