AP Biology Structures of Neurons - Neurons = the most, basic functional unit of the nervous system. * Chemical signal = Neurotransmitters * Electrical signal = Voltage-gated channels - Parts of Neurons a) Dendrites = Receive signals by ion-gated channels; very branch structure b) Axons = Sends signals from cell body by voltage-gated channels c) Soma (Cell Body) = Contains nucleus and organelles d) Myelin sheath = Fatty tissue (Adipose) that increases the speed of signals
