Document Summary
Neuron basic unit of the brain and the nervous system: specializes in receiving and transmitting information. Neuron has several components: cell body centre of neuron containing the basic biological machinery that keeps the neuron alive, dendrites receiving end of the neuron (looks like branches) Terminal buttons of one axon don"t actually touch the dendrites of other neurons: synapse the gap between one neuron and the next. Cerebral cortex wrinkled surface of the brain: made up of ~10 billion neurons, regulates many of the functions that we think of as distinctly human, consists of left and right hemispheres. Hemispheres are linked by millions of axons in a thick bundle called the corpus callosum. Your characteristics/personality are all controlled by different regions of the cortex: frontal lobe responsible for personality and ability to make and carry out plans. Neurons that carry sensory information acquire myelin first (cortex last)
