What is an axon terminal and what does it do?
The axon terminal is located on one end of a neuron or nerve cell. It is the final part of a neuron to receive an electrical impulse and is also the area where the impulse is converted to a chemical signal. It transfers information from its neuron into another neuron, though it does not come into physical contact with the other neuron.
What does the axon terminal connect with?
Axon terminals are that part of a nerve cell that make synaptic connections with another nerve cell or with an effector cell (e.g. muscle cell or gland cell). Likewise, what is inside axon terminals? At the end of an axon, there is a so-called axon terminal that is button-like and is responsible for providing synapse between neurons.
What releases neurotransmitters from axon terminals?
- Neurotransmitter release is dependent on the influx of calcium into the terminal
- SNARE proteins are important for vesicle docking at active zones and exocytosis
- Synaptotagmin is a calcium sensor
Do axon terminals and dendrites form neurons?
Neurons, or nerve cells that carry nerve impulses, are made up of the cell body, the axon, and several dendrites. Signals move across the synapse, the place where the axon of one neuron meets the dendrite of another, using chemicals called neurotransmitters.

Conclusion
- Axon terminals make up the most distal portion of the axon within a neuron and contain structures that are critical for neural communication. Because neurons are separated by synapses, communication is achieved by converting the electrical signals created within the neurons into chemical signals by use of neurotransmitters. The neurotransmitters ar...
Overview
Axon terminals (also called synaptic boutons, terminal boutons, or end-feet) are distal terminations of the telodendria (branches) of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses called action potentials away from the neuron's cell body, or soma, in order to transmit those impulses to other neurons, muscle cells or gla…

Structure
Function
- Axons help with the cable transmission between neurons. They form side branches called axon collaterals so they can send messages to several neurons at once.2 These branches split into smaller extensions known as axon terminal branches, or nerve terminals. Each terminal holds a synapse where neurotransmitters send their messages and where messages ...
