_{<h2>Definition of Axon Terminal</h2>}

An axon terminal, also referred to as a terminal bouton or synaptic bouton, is a specialized structure found at the end of an axon in a neuron. It plays a crucial role in transmitting signals to target neurons or effectors, such as muscles or glands, within the nervous system.

_{<h3>Structure and Function of Axon Terminals</h3>}

Axon terminals are responsible for the transfer of information between neurons, facilitating intercellular communication. They exhibit unique structural features that allow them to efficiently transmit nerve impulses. The terminal ends of an axon contain small swellings called synaptic knobs. These knobs house numerous vesicles filled with neurotransmitters, which are chemical messengers responsible for transmitting signals across the synaptic cleft. The presence of a large number of synaptic knobs enables the axon terminal to establish multiple connections, or synapses, with other neurons or target cells.

_{<h3>Synaptic Transmission</h3>}

When an action potential reaches the axon terminals, it stimulates the release of neurotransmitters from the synaptic vesicles. These neurotransmitters are then released into the synaptic cleft, the narrow space between the axon terminal and the target cell. They traverse this gap and bind to specific receptor molecules on the membrane of the target neuron, initiating a response in the receiving cell. This process is known as synaptic transmission and forms the basis of communication within the nervous system.
