In 4 or 5 sentences, describe the anatomy of the basic unit of the nervous system, the neuron. Include each part of the neuron and a general overview of electrical impulse conduction, the pathway it travels, and the net result at the termination of the impulse. Be specific and provide examples. The human brain contains approximately 100 billion neurons. The anatomical structure of the neuron is made up of a cell body, that includes the cell nucleus and the axons, and the dendrites (Camina & Güell, 2017). The dendrites and the axons allow the neurons to communicate across any distance, long or short, through electrical conduction and chemical transmission. The electrical conduction involves a short electrical fluctuation that propagates down the dendrites, through the cell body, and out at the axon terminal. Chemical conduction on the other hand occurs in the synapse between two neurons, enabling the transmission of nerve impulses from one neuron to another. 2.
