May 22, 2020 · The axon terminal, also known as the synaptic bouton and terminal bouton, is the most distal portion of a neuron’s axon and is critical for neural communication. When action potentials reach the axon terminal, calcium floods the neuron, allowing synaptic vesicles to fuse with the membrane and release stored neurotransmitters to target cells.

Aug 12, 2022 · The axon terminal is the "end-part" of the axon, which lies adjacent to a synapse, the gap between two consecutive neurons. Axon terminals play a fundamental role in facilitating intercellular communication through neurotransmitters.

May 29, 2023 · An axon terminal is any of the button-like endings of axons through which axons make synaptic contacts with other nerve cells or with effector cells. At the axon terminal, synaptic vesicles containing neurotransmitters are docked.

Functionally, the axon terminal converts an electrical signal into a chemical signal. When an action potential arrives at an axon terminal (A), the neurotransmitter is released and diffuses across the synaptic cleft.

Apr 29, 2025 · Axon terminals are essential components of the nervous system, serving as the final destination for electrical signals traveling along neurons. These structures play a role in …

Feb 14, 2024 · Axons are thin fibers that enable communications between neurons (nerve cells). The function of axons is to transmit information in the form of electrical impulses between neurons. From the broadest perspective, axons act like transmission cables.

May 19, 2025 · The terminal of the axon, generally speaking, allows the axon to make connections to other brain cells, in which neurotransmitters, such as dopamine or serotonin, flow through.

The primary function of axon terminals revolves around neurotransmission. When an electrical signal travels down an axon—an action potential—it reaches the axon terminal and prompts a series of biochemical events leading to neurotransmitter release.

Aug 1, 2024 · Axon terminals play a crucial role in neuronal communication by transmitting signals to other neurons or effector cells. One key aspect of axon terminal function is the transport mechanisms that ensure the timely delivery and recycling of essential molecules.

Axons in the CNS often end in fine branches known as terminal arbors (Fig. 2.5C). In most neurons, each axon terminal is capped with small terminal boutons (boutons terminaux, terminal buttons) (Figs. 2.1 and 2.3C, E). These correspond to functional points of contact (synapses) between nerve cells.
