Slide Review Notes 1) Ramon y Cajal: first to demonstrate that the cells of the nervous system are separate 2) Dendrite: receives info from other neurons through synaptic receptors 3) Soma: cell body where all metabolic work occurs and info processing 4) Nucleus: genetic control center - contains DNA 5) Axon: transports signals to other neurons and muscles 6) Myelin Sheath: covers axons to promote speed of signal transportation, contains  nodes of ranvier 7) Terminal Button: pass signal to a target neuron at a synapse that connects to other  dendrites 8) Golgi Appartatus: connected system of membrane that processes and packages  molecules in vesicles 9) Rough ER: a system of folded membranes in the cell body; protein production;  contains ribosomes 10) Smooth ER: a system of folded membranes in the cell body; protein folding, lipid  production/metabolism, calcium regulation 11) Membrane: semi-permeable barrier & gatekeeper that controls exchange and cell- environment interactions 12) Mitochondria: power station; aerobic energy metabolism 13) Lysosome: waste management 14) Cytoplasm: clear internal fluid of the cell 15) Afferent axon: brings information into a structure (sensory neurons) [a-i] 16) Efferent axon: carries info away from a structure (motor neurons) [e-a] 17) Interneurons/Intrinsic Neurons: a single structure that contains both its dendrites and  axons (thalamus) 18) Gray matter: dendrites 19) White matter: axons 20) Glial cells: provide physical support and aid in the immune response a) Ependyal: produces CSF to fill ventricles, and circulates through the brain and  spinal cord 21) Multiple Sclerosis: damage to Oligodendrocytes which disrupts nerve cell  communication 22) Blood-Brain Barrier: semi-permeable  Life of a Neurotransmitter 1) Synthesis of peptide neurotransmitters and vesicles in the soma, as well as smaller

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
