Document Summary

Human brain consists of 100 billion neurons and roughly 100 trillion synapses. Neurons are cells that communicate with one another to perform information-processing tasks. In 1906, camillo golgi and santiago ramon y cajal were jointly awarded the nobel. Prize in recognition of their work on the structure of the nervous system . The nervous system is composed entirely of discrete, individual cells. Neurons are the basic structural and functional unit of the nervous system. Sensory neurons : receive information from the external world and convey this information from the spinal cord to the muscles to produce movement. Interneurons : connect sensory neurons, motor neurons, and other interneurons. Work by biologists alan hodgkin and andrew huxley led to the discovery of the. Resting potential neuron"s resting potential neuron"s cell membrane. Resting potential : difference in electric charge between the inside and outside of a. Action potential : electrical signal that is conducted along an axon to a synapse.
