We each possess approximately one hundred billion neurons in our brain. New neuronal connections and pathways make learning and growing possible. Each rudimentary structure of a neuron has a cell body, axon, and dendrites. Chemical messages called neurotransmitters act as keys, traveling in unidirectional routes from presynaptic axonal terminals across the synapse to dendritic doorways, which unlock vastly powerful biological reactions that help or hinder our physiological processes within out body and mind. We can control various chemicals produced in our soma and brains by creating many of our feelings and emotions through our thoughts, attitudes, behaviors, actions, and reactions toward ourselves, others, situations, and circumstances. Forming new habits can, in turn, produce more dendritic receptors and rearrange synaptic links through what is known as neuroplasticity.
