Document Summary

Chapter 3: structure and function of the nervous system. Central nervous system: brain and spinal chord (cns, encased by bone, cerebrospinal fluid. Peripheral nervous system: cranial nerves, spinal nerves, peripheral ganglia, encased by vertebral column. Directions in nervous system: anterior/rostral front, posterial/caudal back, dorsal top, ventral bottom, lateral toward the side, medial toward the middle, contralateral opposite side. Transverse plane: cross section or frontal section.

Pia mater: last layer of the meninges, adheres to the surface of the brain. Cerebrospinal fluid (csf: clear fluid, fills ventricular system of brain and subarachnoid space surrounding brain and spinal chord. Subarachnoid space: space between arachnoid membrane and pia mater filled with csf.
