Myelin Sheath
The white, fatty material that forms a sheath around the axons of certain nerve cells, which are then called myelinated fibers.
Neurotransmitters
Chemicals released by neurons to transmit signals across a chemical synapse to another neuron or to an effector cell, such as a muscle or gland.
