synaptic vesicles

Synaptic vesicles are tiny, bubble-like structures found in nerve cells. They store and transport neurotransmitters, which are chemical messengers that facilitate communication between neurons. When a nerve signal reaches the end of a neuron, these vesicles fuse with the cell membrane and release their contents into the synapse, the small gap between neurons. This release enables the transmission of signals to the next neuron, playing a crucial role in processes like movement, mood, and many other functions in the brain and body. Essentially, synaptic vesicles are essential for the communication that underpins our nervous system.
