gap junctions(redirected from neuronal gap junctions)
gap junctionsaligned protein membrane channels of two adjacent cells, allowing passage of low-molecular-weight solutes (ions, chemical messengers, amino acids and glucose) directly between cells
regions of high and special ionic permeability between closely apposed cells. They are places at which cells exchange molecules of large size and provide an avenue by which developing cells can influence each other. Called also nexus.
neuronal gap junctions
very tight contacts between some neurons permitting the almost instant transmission of impulses from one neuron to the other; structural elements extend across the gap conferring a continuity of cytoplasm between the cells.
