Abstrakt: Differences in the location of putative inhibitory (F-type) synapses were revealed during research into the ultrastructural organization of the chemically sensitive cat ventrolateral medulla (VLM). These synapses are made up of axonal terminals filled with flattened synaptic vesicles with the long axis measuring 60–80 nm. They are mainly located in the caudal portion of the test area, while S-type synapses with spherical electron-transparent synaptic vesicals, with a mean diameter of 50 nm, are distributed fairly evenly within the confines of the test area. It is postulated that neuronal structure of the chemically sensitive cat VLM have a different functional significance in the exerting of central neurogenous control over circulatory function.
