![]() The diameter of dendrites decreases over time because of their tapering ends. ![]() ![]() Īxons are quite lengthy (several meters) 0.25- over10mmĭendrites are very short strands of tissue (generally below 1.5 mm). The term “axon” refers to the long, thread-like component of a nerve cell that transports nerve impulses away from the cell body.ĭendrites are the small branched extensions of nerve cells that transport nerve impulses from synapses to the cell body. NERVE IMPULSE CONDUCTION Difference between Axon and Dendrite Parameter The axon is located at the distal end of a neuron and relay output message.Ī myelin sheath, a fatty tissue commonly seen on axons which acts as an insulator and significantly increases the conductance of the electrical impulse or message along the axon. An axon can be thinner than the width of the human hair. The length of an axon can range from 1 millimeter in the brain to over 1 meter in the spinal cord. It is possible for certain big axons to transfer impulses up to 90 meters (300 feet) per second. For example, from the spinal cord down to toe.Vertebrate axons are protected by a myelin coating, which speeds up impulse transmission. Axons are extremely small neural fibers that transfer nerve impulses from one neuron to another neuron. A neuron is in charge of processing and relaying the electrical signals involved in receiving sensory information, providing motor instructions to your muscles, and controlling movement. Each neuron contains one axon that connects it to other neurons, muscle cells, or glandular cells. Some axons may be quite long, reaching.
