Document Summary

Nervous system is organized into a hierarchy: central nervous system (cns, peripheral nervous system (pns) Localization of function - different parts of brain responsible for different but overlapping tasks. Lateralization - right and left sides of the brain are partly specialized. Connects sensory receptors and skeletal muscles to the cns (red nerve. Pathways): efferent nerve fibers - transmit information from cns to the periphery (brain -- muscles), afferent nerve fibers - transmit information from the periphery to the cns (sensory receptors -- brain). What is the autonomic nervous system responsible for (3 functions): regulates involuntary behaviour - heart rate/digestion, parasympathetic division conserves energy - eating/sleeping, sympathetic division mobilizes energy - working/danger. Brain - higher order cognitive processes: localization of function: different parts of the brain perform different but overlapping tasks. Spinal cord - bridge between the brain and pns; performs rudimentary (basic) tasks: spinal reflexes - automatic responses to environment that require no higher processing (ex.
