The single process divides into two branches that function as a single axon with a peripheral process and central process. A neuron has many dendrites originated from the cell body. Neurons that have one single process are called neurons. Number (in a single neuron) A neuron has just one axon ( sometimes arising directly from a dendrite, but generally originated from the soma or cell body). Length It is the longest part of a neuron. So this neuron as the name suggests, only has one process. The axon sends impulses away from the nerve body, and the dendrite receives impulses from other nerves. We look at unipolar, bipolar, multipolar, and anaxonic axons in this video. In many cases, the axon is coated by a specialised membrane called a. Comparison Table Between Axons and Dendrites Parameters of Comparison Axons Dendrites Shape Elongated fibre like Usually from the axon of one nerve to the dendrite of another. All neurones have finger-like projections called dendrites and a long fibre called an axon. Unipolar- cell body with one axon only found usually in the embryonic stage. There are small branch-like projections at its terminal which establish a connection with other dendrites and pass the electrical signal to communicate with other neurons. Bipolar- with one axon and one dendrite, found in the retina of the eye.
