Synapses in the Central Nervous System
A number of different synapses have been described in the medulla, cerebellar cortex, and cerebral cortex of the rat. All of these possess the same fundamental fine structure as follows: 1. Close apposition of the limiting membranes of presynaptic and postsynaptic cells without any protoplasmic continuity across the synapse. The two apposed membranes are separated by a cleft about 200 A wide, a...
متن کاملADENOSINE IN THE CENTRAL NERVOUS SYSTEM
Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...
متن کاملP124: Listeriosis in Central Nervous System
Listeriosis is one of the CNS inflammatory diseases which is happened majority in the form of sporadic. Listeriosis is ingested with the food. Infection occurrence in an exposed person depends on the number of organisms ingested, the virulence of the organisms strain and the individual condition. It is known that Listeriosis has decisive importance as an infection which the cellular immunodefen...
متن کاملSynapses in the Central Nervous System* by Sanford
The cytological problems presented by the synapse were carefully considered by Bodian (6) in his review of 1942. He indicated that it is desirable to know more about "the ultrastructure of the membranes concerned, the quantitative relations existing between surfaces of axon terminals and the surfaces Of cells of termination, the intimate relationships of myelin and of glia to synaptic surfaces,...
