139338286Organization of Nervous SystemCNS and PNS; PNS breaks into Sensory and Motor; Motor Breaks into Somatic and Autonomic Nervous Systems; Autonomic breaks into Sympathetic and Parasympathetic Nervous systems1
139338287DendritesReceive nerve impulses toward the cell body2
139338288Inter-neuronsConnect sensory and motor neurons; located in CNS3
139338289Reflex ArcConsists of two or three neurons - a sensory and motor neuron, and sometimes an inter-neuron4
139338290Blood-brain barrierFormed by specialized glial cells and lines capillaries in the CNS which restricts the passage of harmful chemicals from the blood into the CNS5
139338291Refractory PeriodThe lag time in which a neuron cannot fire because the neuron must reach -70 millivolts6
139338292Nodes of RanvierGaps in myelin sheath in vertebrates7
139338293Salatory ConductionWhen an action potential leaps from node to node which speeds up nerve impulses8
139338294Excitatory Postsynaptic Potential (EPSP)When NA+ gates open and the membranes moves toward the threshold potential. An action potential is generated if this happens9
139338295Inhibitory Postsynaptic PotentialWhen K+ gates open and the membrane becomes more polarized. Generating an action potential in this cell is more difficult10
139338296AcetycholineFound at neuromuscular junctions; stimulates muscles to contract11
139338297Neuromuscular JunctionsGaps between motor neurons and muscle cells12
139338298Epinephrine, Norepinephrine, Dopamine, SerotoninDerived from amino acids and are secreted into synapses between neurons13
139338299Gamma Aminobutyric Acid (GABA)An inhibitory neurotransmitter among neurons in the brain14
