Where is the terminal button located?

The terminal button, also known as the synaptic bouton, is found at the end of the axon. This structure plays a crucial role in neuronal communication. When an electrical signal, or action potential, travels down the axon, it reaches the terminal button, where neurotransmitters are stored and released into the synapse—the gap between neurons. This release is essential for transmitting signals to other neurons, muscles, or glands.

Understanding the location of the terminal button is key to grasping how neurons communicate and how information is processed in the nervous system. Each neuroanatomical structure serves a specific function, and the terminal button's position at the end of the axon allows it to effectively release neurotransmitters to initiate communication with adjacent cells.
