Synapses

Synapses are the junctions where two nerve cells, or neurons, communicate with each other. When a nerve signal, or impulse, reaches the end of one neuron, it releases chemicals called neurotransmitters. These chemicals cross the synapse, the small gap between neurons, and attach to specific receptors on the receiving neuron. This interaction can initiate a new nerve impulse in the second neuron, allowing signals to be passed along the nervous system. Synapses play a crucial role in transmitting information throughout the brain and body, influencing everything from reflexes to complex thoughts and emotions.
