Summary

The authors studied the innervation of the caecum in cats. Acetylcholinesterase (AChE)- and butyrylcholinesterase (BuChE)-positive nerve profiles were visualized by the direct tiocholine method. AChE- and BuChE-positive nerve components enter the caecum "from outside" in a common bundle with arteries and line these vessels in the form of plexiform bundles of nerve profiles as far as their terminal ramification in the organ wall. Nerve fibres, supplying both the longitudinal and circular layer of the wall of musculature, branch away from the periarterial AChE- and BuChE-positive nerve plexuses as well as nerve profiles entering the neuropil between neurocytes of myenteric and submucous plexuses. Moreover, they form loose nerve fibres in the lamina muscularis mucosae and penetrate also the lamina propria mucosae and the mucous crypts. AChE- and BuChE-positive nerve fibres run around lymphoid follicles or between them, and do not penetrate into the follicles, or B-dependent parts.
