Document Summary

The neuron has dendrites, axons, a cell body, a myelin sheath, and nodes of ranvier. The axons take that input and send it out to other dendrites. The cell body conducts the electricity the neuron needs to send the signal. The myelin sheath insulates the axon so that it is protected from its surroundings, and is able to send signals faster. The nodes of ranvier allow the nerve impulses to move along the neuron by de-polarisation and re-polarisation of the nerve membrane. There is the temporal lobe that is responsible for hearing. Then there is the occipital lobe that works in vision. And there is the frontal lobe, which does the planning, thinking, and other cognitive processes. The sensory areas make you aware of sensation, the association areas give meaning to those sensations, and the motor areas allow you to act upon that sensation. The main functional areas of the cortex are the sensory areas, cortex areas, and association areas.
