An axon is a highly branched structure with each branch terminating as a swollen or enlarged button, which is a synaptic knob. It is known by different names like synaptic terminal, axon terminal, synaptic bouton, and terminal bouton. Overview of Synaptic Knob
Axon - Wikipedia
WebNeurons are usually described as having one, and only one, axon—a fiber that emerges from the cell body and projects to target cells. That single axon can branch repeatedly to communicate with many target cells. It is the axon that propagates the nerve impulse, which is communicated to one or more cells. WebThe cell body contains a specialized structure, the axon hillock that “integrates” signals from multiple synapses and serves as a junction between the cell body and an axon. Axon: An axon is a tube-like structure that propagates the integrated signal to specialized endings called axon terminals. rays on the run
