What is "telodendron"

n. a telodendrion

Telodendron (plural: telodendria; from meaning "tree + end") is a distal branch of a neuronal axon that can further branch into axon terminals. While each neuron only has one axon, it can branch into several telodendria and form presynaptic vesicles for neurotransmission at each branch.

Many telodendria may also receive synaptic input, making them part of the dendritic zone as well.
