It contrasts the fast, short duration nervous system with the slower endocrine backup, then breaks down central nervous system as the brain and spinal cord for integration and control, and the peripheral nervous system as communication pathways including cranial and spinal nerves. It explains sensory and motor divisions, with motor further divided into somatic voluntary muscle control and autonomic involuntary control, including sympathetic fight or flight and parasympathetic rest and digest. It covers neuron structure and function, key reflex components, and major neuroglia types in the CNS and PNS, including CNS myelin from oligodendrocytes versus PNS myelin from Schwann cells."}
