Document Summary

Neurons are cells in the nervous system that communicate with one another to perform information-processing tasks. Principle functional unit of the nervous system. The human brain consists of roughly 100 billion neurons and roughly 100 trillion synapses. Discovery: camillo golgi and santiago ramon y cajal, 1906, awarded with a nobel prize for their work on the structure of the nervous system. The neuron doctrine: the nervous system is composed entirely of discrete, individual cells, neurons are the basic structural and functional unit of the nervous system. Glial cells: provide structural support and chemicals/nutrients to neutrons, carry waste away from the cell, help maintain a blood/brain barrier, capable of communicating with one another and to neutrons, via chemical signals. The synapse: gap across which one neuron connects with another, point of chemical communication between a terminal button and a receiving dendrite, parts of the synapse, vesicles, synaptic gap, neurotransmitters, receptor site, sending neuron, receiving neuron.
