An axon can divide into many branches called telodendria (Greek for 'end of tree'). At the end of each telodendron is an axon terminal (also called a terminal bouton or synaptic bouton, or end-foot). [20] Axon terminals contain synaptic vesicles that store the neurotransmitter for release at the synapse. This makes multiple synaptic connections ...
Axon terminals (also called terminal boutons, synaptic boutons, end-feet, 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 ...
Schaffer collaterals are axon collaterals given off by CA3 pyramidal cells in the hippocampus.These collaterals project to area CA1 of the hippocampus [1] and are an integral part of memory formation and the emotional network of the Papez circuit, and of the hippocampal trisynaptic loop.
Established collateral branches, like the main axon, exhibit a growth cone and develop independently of the main axon tip. Overall, axon elongation is the product of a process known as tip growth. In this process, new material is added at the growth cone while the remainder of the axonal cytoskeleton remains stationary.
The unmyelinated, preterminal axons with very long varicose branches are present in small axon bundles and varicose terminal axons are present as single isolated axons. The small axon bundles run parallel to and between muscle bundles and the "en passage" varicose axons are the main sources of innervations to the gut smooth muscle bundles.
An autapse is a synapse in which the axon of one neuron transmits signals to its own dendrite. The general structure of the dendrite is used to classify neurons into multipolar, bipolar and unipolar types. Multipolar neurons are composed of one axon and many dendritic trees.

Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [ 1 ] In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers , and commissural fibers . [ 1 ]
