Dendrites possess receptors but axons do not. An axon or nerve fiber is a long slender projection of a nerve cell or neuron that conducts electrical impulses away from the neuron’s body or soma. A dendrite has spines on its surface to get attached to axons of other neurons but axon does not. Rather than mere quirk or curiousity the axon carrying dendrite, or AcD as the authors call it, is found on most neuronsat least among pyramidal cells in the CA1 area of the mouse hippocampus. An axon forms a synaptic knot at the end but a dendrite does not. The axon is an extension from the body of a nerve cell. A dendrite is a continuous structure while an axon has small gaps between its outer Schwann cells. Each different type of nerve cell has a unique pattern of dendrite growth and any one neuron can receive multiple connections from many other nerve cells. The dendrites branch and terminate in the vicinity of the cell body. The dendritic spines receive the majority of axon terminals synapsing with dendrites of pyramidal and spiny stellate neurons, but electron microscopic. These axons can be a few millimetres to more than one metre long. Nerve cells communicate by electro-chemical signals that are transmitted into the dendrites. A neuron typically has many dendrites and one axon. The axons and dendrites are seen as the signal-carrying and. Here we review the evidence that axon/dendrite formation during neuronal. Dendrite receives the electric signalĪn axon passes the information from the cell body (Soma) to the dendrite of another neuron in the form of an electrical impulse through the synaptic gap. The cell body, home to the nucleus, has long been considered the control center of the neuron. Differentiation of axons and dendrites is a critical step in neuronal development. Function It transmits the electrical signal from the soma or cell body A neuron has many dendrites originated from the cell body.
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. Parameters of Comparison Axons Dendrites Shape Elongated fibre like
