Dendrites- a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body
Synapes- a structure that permits a neuron to pass an electrical or chemical signal to another neuron
Axon- the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells
Myelin Sheath- the insulating covering that surrounds an axon with multiple spiral layers of myelin, that is discontinuous at the nodes of Ranvier, and that increases the speed at which a nerve impulse can travel along an axon—called also medullary sheath.
Action Potential- the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell
Starting at the cell body, the signal travels down the axon from the presynaptic neuron after meeting its action potential and carries an electrical charge through the synapse. This process is sped up by the use of the myelin sheath.
