![]() Each dendrite is about 2 µm long and usually 5 – 7 dendrites are present and usually form a complex interwoven structure near the neuron which is referred to as a dendritic tree.Dendrites are shorter structures that taper off towards the ends.Dendrites are an integral part of the mammalian central nervous system.Dendrites: Dendrites are the protoplasmic projections found at the terminal end of the neuron and they function to receive the cellular signals from the other neurons through neuronal synapse.Axons have voltage-gated Sodium ion channels that propagate the electrical signals along their length to reach the synapse. Axons function to send the electrochemical signals. Axons are longer than dendrites and have almost the same diameter throughout their length. It functions to carry information away from the cell body towards the axon terminals and eventually transmit it to another neuron. Axon: Axon is the single, protoplasmic tubular projection arising from the cell body of the neuron.Cell body: The cell body or soma is the nucleus of the neuron cell that contains, the endoplasmic reticulum, Golgi bodies, mitochondria, and other cellular components.All individual neurons have these three fundamental parts: ![]() While the motor neurons transmit the signals from the brain to the muscles. There are sensory neurons throughout the body that collect sensory stimuli from the sensory receptors of the body and send them to the brain to process them. ![]() Neurons are the building blocks of the nervous system, that receive the signals/information from one part of the body and transmit it to the other part of the body. Briefly, let us understand the structure of neurons. ![]()
