Neuron Doctrine - 1.The brain is composed of separate cells that are distinct structurally, metabolically, and functionally 2."Information" is transferred from neuron to neuron/cell across tiny gaps. This connection is called a synapse Camillo Golgi - discovered golgi apparatus Ramon y Cajal - father of modern neuroscience Dendrite - dendrite spines - Soma - Neucleus - axon hillock - Axon - axon collaterals - myelin sheath - Nodes of Ranvier -axon terminal/Presynaptic Terminal - presynaptic membrane - synaptic vessicles - Neurotransmitters - synaptic cleft - postsynaptic membrane - neurotransmitter receptors - Transduction - the transformation of sensory stimulus energy into a cellular signal, such as receptor potential Axon vs Dendrite - Axon - Few branches, smooth, no RER/Ribosomes, one per cell<div>Dendrite - many branches, rough with spines, LOTS of RER/Ribosomes, many of them</div> Classifying Neurons - Shape, genetics, content, location, target Neuron Classification: Structural - multipolar, bi
