| 139338286 | Organization of Nervous System | CNS and PNS; PNS breaks into Sensory and Motor; Motor Breaks into Somatic and Autonomic Nervous Systems; Autonomic breaks into Sympathetic and Parasympathetic Nervous systems | 1 | |
| 139338287 | Dendrites | Receive nerve impulses toward the cell body | 2 | |
| 139338288 | Inter-neurons | Connect sensory and motor neurons; located in CNS | 3 | |
| 139338289 | Reflex Arc | Consists of two or three neurons - a sensory and motor neuron, and sometimes an inter-neuron | 4 | |
| 139338290 | Blood-brain barrier | Formed by specialized glial cells and lines capillaries in the CNS which restricts the passage of harmful chemicals from the blood into the CNS | 5 | |
| 139338291 | Refractory Period | The lag time in which a neuron cannot fire because the neuron must reach -70 millivolts | 6 | |
| 139338292 | Nodes of Ranvier | Gaps in myelin sheath in vertebrates | 7 | |
| 139338293 | Salatory Conduction | When an action potential leaps from node to node which speeds up nerve impulses | 8 | |
| 139338294 | Excitatory Postsynaptic Potential (EPSP) | When NA+ gates open and the membranes moves toward the threshold potential. An action potential is generated if this happens | 9 | |
| 139338295 | Inhibitory Postsynaptic Potential | When K+ gates open and the membrane becomes more polarized. Generating an action potential in this cell is more difficult | 10 | |
| 139338296 | Acetycholine | Found at neuromuscular junctions; stimulates muscles to contract | 11 | |
| 139338297 | Neuromuscular Junctions | Gaps between motor neurons and muscle cells | 12 | |
| 139338298 | Epinephrine, Norepinephrine, Dopamine, Serotonin | Derived from amino acids and are secreted into synapses between neurons | 13 | |
| 139338299 | Gamma Aminobutyric Acid (GABA) | An inhibitory neurotransmitter among neurons in the brain | 14 |
