Just like how Alison was the main building block of the Liars. Dendrites The branching extensions of a neuron that receive impulses, such as the Liars receiving information from A. Axon The extension of a neuron through which messages are sent to other neurons or to muscles or glands. Toby was an extension of Spencer who sent out messages as A. Myelin Sheath A layer of tissue that encases neurons. It enables faster transmission of neural impulses. The Liars' families and their secrets protect the Liars, yet A uses them to get across their message more clearly. Threshold The level of stimulation required to trigger a neural response. After finding Toby was A, Spencer's threshold for tolerating Mona sunk to an all-time low. Acetylcholine A neurotransmitter that triggers muscle contraction. Such as the neurotransmitter that makes Pretty Little Liars fans twitch every time Toby comes on screen. Central Nervous System The brain and the spinal cord, which are linked to survival... something Alison was terrible at. Autonomic Nervous System The part of the peripheral nervous system that controls the internal organs. Such as the gorgeous boys of the show who control the hearts of the
