Lesson
Neurons
Electrical signals inside the cell, chemical signals across synapses.
Explanation
Neurons communicate using electrical signals within the neuron and chemical signals across synapses. Dendrites generally receive information, the cell body integrates signals, and the axon carries the neural impulse toward other cells.
