It is also part of the normal learning process.After axon severing, neurons recover function by reinitiating axon outgrowth. Growing dendrites is a normal healing process of the brain. Once the growth stops, they generate small specialized protrusions known as dendritic spines for nerve impulse transmission.Ībsolutely. It is responsible for receiving electrochemical impulses from the external environment and rely them on the axon hillock.īetween 8-13 years. Both are cytoplasmic projections in the cell bodyįrequently Asked Questions (Dendrite vs Axon).Dendrite originate from the nerve cell whereas axon originates from the axon hillock.Dendrites have ribosomes while axon does not have ribosomes.Dendrite receive messages from the external environment while axon sends messages from the body cell to the external environment.Dendrites contain both neurofibrils and Nissl’s granules while axon has only neurofibrils.The terminal branches of axon form enlarged synaptic knot while dendrites have no such vesicles.Axon has braches at the distal ending while dendrite has branches throughout its length.Dendrite is highly branched throughout its length while axon thickness is uniform throughout its length.Dendrite is comparatively short whereas axon is comparatively long.Dendrite arise from the receiving surface of the nerve whereas axon arises from the discharging end of the nerve.Axon occur in a single form in each neuron whereas dendrite occur in numerous form in each neuron.Main Difference between Dendrite and Axon in Point Form They are connected with the other muscles, neurons, and gland cells. What Is Axon?Īxons are nerve fibers that are part of the neuron that carries signal informs of nerve impulses from the cell body to the external environment.Įach nerve cell has one axon which tends to be long and slender. The short projections and tapering ends happen to be the reason why dendrites are non-myelinated. These special receptors occur on the exterior of the dendrites. The electrochemical message is transmitted through special receptors in the form of neurotransmitters. The core significance of dendrite is to receive nerve impulses from other synapses and forward them to the body cell. These branches are responsible for helping and supporting to receive impulse signals from other synapses. They have branches spread out like the shape of a tree. Have a uniform thickness throughout their lengthĬonduct neuron impulses away from the somaĭendrites are the outgrowth part of a neuron. They tend to be single in a cellĪrise from the receiving surfaces of the nerveĪrise from the discharging end of the nerve It is a projection of nerve cells which is long and slender. It is an expansion of nerve cells with short branch development and numerous in the cell The core difference between dendrite and axon is that dendrite receives the electrochemical impulses from the external environment while the axon sends electrochemical impulses to the external environment.Ĭomparison Table between Dendrite and Axon Basic Terms They play a vital role in the transmission of nerve impulses to various parts of the body. The nervous system has some nerve cells responsible for sensitivity. What is the difference between dendrite and axon?
