READ: They key to large-scale communication in the entire nervous system is the ability to pass nerve impulses on a small scale from one neuron to the next so that signals can be transmitted throughout the entire body. The junction between two neurons is called a synapse, and is the critical space that mediates the transfer of a signal from the presynaptic neuron (the sender) to the postsynaptic neuron (the receiver) or even an effector cell (like a gland or muscle cell.) You circled a synapse in Model 1. Synapses can be electrical or chemical. Electrical synapses transmit electrical signals via gap junctions. A channel protein connects the cytoplasm of two adjacent neurons so that ions can flow directly from one cell to another to pass on the signal. However, the most common type of synapse is a chemical synapse. These utilize chemical signals, called neurotransmitters, to transmit the signal across the synaptic cleft. This is a slower process, but allows for much greater precision…
