That’s not an exotic plant, but a NEURON under the microscope A neuron is an electrically excitable cell that processes, stores, and transmits information using electrical and chemical signals. The cell contains a nucleus, a cell body, and processes (dendrites and axons). If we can say so, the neuron is the most "sprouted" cell in the human body, as its dendrites and axons stretch out like wires, connecting the neuron to other neurons.
