NEUROBIOLOGICAL BASES OF BEHAVIOR Peripheral Nervous System  2 Want big impact? USE BIG IMAGE.  Peripheral NS 3 co n ta in s a l l n e r ve s t h at l ie outside the Central NS primary role: to connect organs, limbs, and skin allows the brain and spinal cord to receive and send information to other areas of the body in cl u d e s cra n ia l a n d s p in a l nerves  Peripheral NS 4 CRANIAL NERVES res pons ibl e for carrying information in and out of the brain 10 originate from the brain and mainly control the voluntary movement and structures of the head  Peripheral NS 5 CRANIAL NERVES The nucleus of the olfactory and optic nerve are located in the fo rebrain an d th al amu s , r e s p e c t i v e l y, a n d a r e n o t considered cranial nerves  Peripheral NS 6 SPINAL NERVES carry somatosensory information into and motor instructions out of the spinal cord arise from the SC as nerve roots and merge to form a web (plexus) or interconnected nerve roots and once again branch to form nerve fibers  Somatic NS 7 associated with the voluntary control of the body movements via the use of skeletal muscles responsible for all functions we are aware of and can consciously influence consists of both af fe rent and efferent nerves  Autonomic NS 8 res po n s ibl e fo r regu l atin g involuntary body functions, such as b l o o d fl o w, h eartb eat , digestion, breathing, etc Sympathetic NS: regulates the fight-or-flight response Paras ympat het i c N S : h e l p s maintain normal body functions and conserve physical resources 9 CREDITS 10 » ncbi.nlm.nih.gov/books/NBK556027/
