Document Summary

430-452: connected as a single unit, but anatomically divided into 2 parts, central nervous system: brain + spinal chord; integrating & command center. Peripheral nervous system: cranial & spinal nerves; communication between cns & all parts of body: sensory division: somatic & visceral fibers; from receptors to, motor division: motor nerve fibers from cns to effectors. Cns (muscles & glands: somatic ns: voluntary; from cns to skeletal muscle, autonomic ns: involuntary; (visceral motor); from cns to cardiac muscle, smooth muscle, glands, sympathetic division: fight or flight , parasympathetic division: conserve energy at rest. Histology of nervous tissue: very cellular; minimal extracellular matrix, 2 principal types of cells, neurons. The brain (chapter 12: complexity of wiring rather than size is what matters, subdivisions, cerebral hemispheres, diencephalon (thalamus, hypothalamus, epithalamus, brain stem (midbrain, pons, medulla, cerebellum. Ventricles of the brain spinal cord: continuous with one another and with central cavity of, filled with csf & lined by ependymal cells.
