What is the function of the bouton?

Answer 1

The bouton, often referred to as the nerve terminal or synaptic bouton, is a specialized structure at the end of a neuron that facilitates communication with other neurons or target cells. Its primary function is to release neurotransmitters into the synaptic cleft, enabling the transmission of signals across synapses. This process is crucial for neuronal communication, influencing various physiological processes including muscle contraction, reflexes, and emotional responses. Additionally, boutons play a role in the modulation of synaptic strength, which is important for learning and memory.
