Where are terminal buttons located

A)  at the end of dendrites
B)  at the end of axons 
C)  on the soma
D)  in the synaptic cleft

Terminal Buttons

Terminal buttons are the small nodules at the end of axons that release chemical neurotransmitters, which facilitate the transmission of signals from one neuron to another.

Axons

Long, threadlike parts of a nerve cell along which impulses are conducted from the cell body to other cells.

Dendrites

Branch-like extensions of neurons that receive signals from other neurons and transmit them toward the cell body.
