Document Summary

Connections: the structure of nerve cells reveal their penchant for connectivity. Some of the more tractable pathways of neural information flow are those between the central and peripheral nervous system. Relationship between the cns and the pns. Root systems that are made of lots of little rootlets. Autonomic nervous system - particular efferent system from the center to the periphery and is pretty important for homeostatic functions. Efferent is output from the center and afferent is coming to the center. Tracts are bundle of nervous system in the cns and nerve bundle in the periphery. Peripheral nerve axons can be either efferent (carrying signals from the cns) or afferent (carrying signals to the cns) Although mixed in the peripheral nerves, they have separate pathways, spinal roots, connecting to the cns. In the mixed peripheral nerves the afferent and efferent are all mixed together and even look the same, there is nothing about them that can differentiate them.
