Limbic System |
This functional complex important in controlling emotional responses |
|
Sympathetic Division |
Paravertebral ganglia are associated with this division of the autonomic nervous system |

Postganglionic |
Conducts impulses from the ganglion to visceral effector, thinner and non myelinated (SLOW) |
|
Somatic Neurotransmitter |
ALWAYS ACH and excitatory |
|
Preganglionic Fibers |
Oculomotor, Facial, Glossopharyngeal, Vagus |
|
Sympathetic Division |
FIGHT OR FLIGHT |

Ventral root |
Axons of motor neurons |
|
Dorsal root ganglion |
Gray matter made of sensory neuron cell bodies |
|
Dorsal root |
Made of axons, sensory neurons |
|
Schwann Cells in PNS |
Insulation |
|
Oligodendrocytes in CNS |
Insulation
|
|
Astrocytes |
SUPPORT (Responsible for brain tumor because they divide by mitosis) |
|
Ependymal cells |
Produce CSF by feeding with nutrients |
|
Microglia |
Protection (fights away bacteria) |
|
Ganglion |
A cluster of neuron cell bodies in the PNS |

Tract |
A group of nerve fibers that run together in the CNS |
|
Convergence |
Type of circuit in which many neurons send input to one postsynaptic neuron |
|
Ethmoid Bone |
Cristigale/Cripiform Plate |
|
Alzheimers |
Without ACH what happens |
|
Resting Membrane Potential |
Electrical charge/potential difference that exsists across the cell membrane |
|
Depolarization |
Membrane becomes positive from -70mV, opening sodium channels |
|
Repolarization |
Membrane potential returns to resting value -70mV, due to opening potassium channels |
|
Faster impulse conduction |
Large Diameter, Myelinated, Hot Temperature, LOW Ca2+ in ECF (HYPOCALCEMIA)
|
|
Slower impulse conduction |
Hypoxia, Anaesthetics, toxins that block voltage, Metabolic poisons, HYPERCALCEMIA, HYPOKALEMIA |
|
Synapse |
Specialized junction between two neurons through electrical activity from one neuron is passed on to the other neuron |
