Study Guide 8 BIOL&241 NERVOUS SYSTEM: BRAIN & CRANIAL NERVES FALL-2021 LATEST SOLUTION AID GRADE A+

The Core Concepts in the following chapters include: • Levels of Organization. The structure and function of the NS at the a cellular (CSF), sub- cellular (axons and myelin), cellular (neurons and neuroglia), CNS structure (different CNS regions) and organ (brain and spinal cord) levels of organization is important to understand. • Homeostasis. Particular NS structures are important in the homeostatic regulation of variables such as blood pressure, pH, osmolarity, etc. The role of sensory receptors is essential for homeostasis. • Interdependence. Sensory, motor and association areas work together and damage to one region can affect the function of another. • Cells. The function of the NS depends on the specialization of cell function. • Cell-cell communication. Cell-cell communication (cell-signaling) between neurons via synapses, between neurons and neuroglia and between neurons is the primary function of the NS. • Structure/Function. Some functions are localized to particular regions of the CNS. The structures of the meninges enable their particular functions. The structure of sensory receptors and organs determines their functions.
