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.
Axon terminals (also called synaptic boutons, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those impulses to other neurons ...
An axon typically develops side branches called axon collaterals, so that one neuron can send information to several others. These collaterals, just like the roots of a tree, split into smaller extensions called terminal branches. Each of these has a synaptic terminal on the tip.
Apr 5, 2023 · Terminal buttons are found at the end of the axon, below the myelin sheath, and are responsible for sending the signal on to other neurons. At the end of the terminal button is a gap known as a synapse.
Nov 21, 2023 · What do terminal branches do? The terminal branches of an axon change electrical impulses or action potentials within a neuron into chemical messages in the form of 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.
