Document Summary

Integration and command: peripheral nervous system, nerves, communications iii. If the nervous tissue is outside of the cns then it is peripheral c. Integration center: motor neuron, effector, monosynaptic reflexes, no interneuron, one synapse, polysynaptic reflexes, multiple interneurons, multiple synapses. Has a tale on lateral view: touching on top. iii. Whatever brain part is near its serviced by whats closest: c-shaped lat ventricles are draining into 3rd vent, donut shaped cavity h. Alphamotor neuron lives in spinal chord: cerebral white matter, commissural fibers, axons who communicates both sides of brain, their tract is always lateral, largest is corpus callosum, associational fibers i. Intrahemispheric: long or short, how they communicate iv. Internal capsule is very long one: projection fibers, cortex lower cns regions, vertical fibers, deep grey matter, basal ganglia (pink nuclei) i. Initiates and terminates body movements: suppresses unwanted movements, not an actual ganglia, it"s a nucleus, diencephalon, thalamus, hypothalamus, epithalamus (caudal aspect of thalamus, thalamus i. ii.
