Document Summary

Stimulus stimulates receptors that change the stimulus into electrical signals. These go throughout the brain in order to create responses. We also receive knowledge and use knowledge throughout this process. Neurons are the building blocks and transmission lines of the nervous system. There are around 180 billion of them in the brain. Neurons: make up the brain, transmit electricity and communicate with one another, they are specialized to receive and transmit information from/to the nervous system, environmental energy is made into electrical energy for this transmission of information to occur. Golgi: confirmed the existence of neurons by staining some neurons (leaving most unstained) and seeing/figuring out the structure of single neurons. Structure of neurons (1) cell body: keeps cell alive (2) dendrites: branch out and receive signals (3) axon: transmits signals. This nerve fibre tube conducts electrical signals (4) sensory receptor: instead of cell body/dendrites.
