Dendrite:-  They are tree like projections generally the extension of nerve cell which helps in the transmission of nerve impulses or electrochemical stimulation from one neuron to another. It is also known as dendrons. For neurons to become active they need some action potential, these action potentials are received in the form of nerve impulses or electrochemical stimulation by dendrite and is been stored  in the cell body, or soma, of the neuron. Dendrites are covered by synapses (Structure that permit neural transmission).
