Document Summary

The workings of the brain depend on cross-talk among neurons: neurons: nerve cell specialized for communication, our brains contain about 100billion neurons. Neurons contain several other components that collaborate to help our nervous systems functions. Materials needed by the neuron are made here. Manufactures new cell components, which consist of small and large molecules contains the nucleus (proteins are manufactured) central region of the neuron therefore, damage to this part of the neuron is fatal. Projection that picks up impulses from other neurons. Neurons have branchlike extensions for receiving information from other neurons called dendrites.
