WebAug 13, 2024 · An axon is a tube-like structure that propagates the integrated signal to specialized endings called axon terminals. These terminals in turn synapse on other neurons, muscle, or target organs. Chemicals released at axon terminals allow signals to be communicated to these other cells. WebThe outer membrane of the axon is called axolemma and the cytoplasm is known as axoplasm. Telodendria, end branches of axons, have a swollen end known as axon terminal. Axon terminals are specialized structures that connect the axon to a dendron or the cell body of another neuron. Web60.
