80/20 Neurological Assessment & Physiology Summary 1. Structure & Cellular Biology Organization: The CNS consists of the brain, spinal cord, and CN I-II[1]. The PNS contains CN III-XII, spinal nerves, and the ANS[1].Cells & Myelin: Neurons conduct action potentials via saltatory conduction across nodes of Ranvier, accelerated by myelin[2]. Astrocytes form the blood-brain barrier and create scar tissue (gliosis) upon injury[2]. Oligodendrocytes myelinate CNS axons; Schwann cells myelinate PNS axons[2][3].Synapses: Neurotransmitters cross synapses to alter impulse transmission, using excitatory (glutamate) or inhibitory (GABA) pathways[4].2. Pathways, Lobes & Perfusion Tracts: Ascending tracts carry sensory input (spinothalamic for pain/temp...
