[Submicroscopic localization acetylcholinesterase in synapses of the caudal mesenteric ganglion in cats].
The existence of two types of synapses in the cat caudal mesenteric ganglion was studied using Karnovsky's electron microscopic method. Synapses of the first type contain light agranular synaptic vesicles and show acetylcholinesterase-positive response, which implies their cholinergic nature. Synapses of the second type show weak positive or negative AChE-responses. These synapses most of which contain also granular vesicles are considered to be noncholinergic. AChE-positive and AChE-negative synapses were found also in predecentralized ganglia. The origin of the two types of synapses is discussed.
