Both axon and dendrite are branched structures.Both axon and dendrite transmit nerve impulses.Both axon and dendrite are projections of the cell body of a nerve cell.Since dendrites are short projections, they are not myelinated. A cross-section of an axon is shown in figure 1.ĭendrites possess tapering ends. The axon hillock is the initial segment of an axon. Vesicles that contain neurotransmitters are present in the axon terminals to transmit the nerve impulses by means of chemical signals through the synaptic gap. The membrane of the axon terminal is linked to the membrane of the target cell. The axon terminals form the synaptic connection with a dendron of another neuron or with an effector organ. The axon terminals are the swollen ends of the telodendria. The tips of the branched ends are formed by telodendria. Axons are branched at their terminal ends. The membrane that covers the axon is called the axolemma. Axons carry nerve impulses away from the cell body. Key Terms: Axon, Axon Hillock, Cell Body, Dendrites, Myelin, Myelinated Nerve Fibers, Nerve Cells, Non-Myelinated Nerve FibersĪn axon is single, long projection of a nerve cell. What is the Difference Between Axon and Dendrite What are the Similarities Between Axon and DendriteĤ. The main difference between axon and dendrite is that axon carries nerve impulses away from the cell body whereas dendrites carry nerve impulses from synapses to the cell body. The short structures that extend from the cell body are called dendrites. An axon is a long conical prolongation of the cell body of the nerve cell. They transmit nerve impulses to the brain, spinal cord, and to the body to coordinate the functions of the body. Nerve cells are the structural and functional units of the nervous system of animals.
Axon and dendrite are two components of nerve cells.
