Key Points. 1  Dendrites are the tree-like structures in neurons that extend away from the cell body to receive messages from other neurons at synapses; not all neurons have dendrites. 2  Synapses enable the dendrites from a single neuron to interact and receive signals from many other neurons.
The neuron (nerve cell) is the fundamental unit of the nervous system. The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands.Neurons are designed to rapidly send signals across physiologically long distances.They do this using electrical signals called nerve impulses or action potentials.When a nerve impulse reaches the end of a neuron, it triggers the release of a chemical, or neurotransmitter. The neurotransmitter travels rapidly across the short gap between cells (the synapse) and acts to signal the adjacent cell.hey do this using electrical signals called nerve impulses or action potentials.
