Witryna11 kwi 2024 · Remarkably, astrocytes exhibit the highest expression level of connexins (Cxs), the gap junction channel–forming proteins. When aligned between adjacent cells, these proteins connect their cytoplasm, enabling direct intercellular communication by diffusion and redistribution of small molecules [ 4 – 7 ], with a molecular weight up to … WitrynaSynapses Where two neurons meet there is a small gap called a synapse. An electrical impulse cannot directly cross the gap so a different mechanism has to be used. An …

The neurotransmitter may initiate an electrical response or a secondary messenger pathway that may either excite or …
