THE HUMAN NERVOUS SYSTEM  THE HUMAN NERVOUS SYSTEM IS BROKEN INTO TWO CATEGORIES  THE CENTRAL NERVOUS SYSTEM (C.N.S) VS.  THE PERIPHERAL NERVOUS SYSTEM (P.N.S)

THE HUMAN NERVOUS SYSTEM  THE CENTRAL NERVOUS SYSTEM  INTERPRETS AND RESPONDS TO ALL STIMULI  COMPOSED OF THE BRAIN AND THE SPINAL CORD

THE HUMAN NERVOUS SYSTEM  WHAT’S THE DIFFERENCE BETWEEN THE SPINAL CORD, AND THE SPINE?  THAT’S LIKE ASKING “WHAT’S THE DIFFERENCE BETWEEN THE BRAIN AND THE SKULL?”…SO WHAT’S THE ANSWER?  FUN TERMS ASSOCIATED WITH THIS:  CONCUSSION  MENINGES  CEREBROSPINAL FLUID (C.S.F.)

THE HUMAN NERVOUS SYSTEM  THE HUMAN BRAIN

THE HUMAN NERVOUS SYSTEM  THE HUMAN BRAIN

THE HUMAN NERVOUS SYSTEM  THE HUMAN BRAIN  CEREBRUM  CORPUS CALLOSUM  CEREBRAL CORTEX  CEREBELLUM  MEDULLA OBLONGATA

THE HUMAN NERVOUS SYSTEM  THE SPINAL CORD  IMPORTANT FUNCTIONS  CONNECTS P.N.S. TO BRAIN  CONTROLS CERTAIN REFLEXES

THE HUMAN NERVOUS SYSTEM  THE PERIPHERAL NERVOUS SYSTEM  ALL THE NERVES THAT AREN’T THE BRAIN OR SPINAL CORD…WE CALL THEM CRANIAL NERVES, OR SPINAL NERVES, RESPECTIVELY; WHY?!?!  WE BREAK THE PERIPHERAL NERVOUS SYSTEM INTO TWO GROUPS  SOMATIC NERVOUS SYSTEM VS. AUTONOMIC NERVOUS SYSTEM

THE HUMAN NERVOUS SYSTEM

 SOMATIC NERVOUS SYSTEM  INVOLVED IN ALL VOLUNTARY MOVEMENTS/RESPONSES…EXAMPLES??  AUTONOMIC NERVOUS SYSTEM  INVOLVED IN ALL INVOLUNTARY, OR AUTOMATIC, MOVEMENTS/RESPONSES…EXAMPLES??

THE HUMAN NERVOUS SYSTEM  AUTONOMIC NERVOUS SYSTEM  BROKEN INTO TWO DIVISIONS  SYMPATHETIC (S  SPEEDS THINGS UP) VS PARASYMPATHETIC (P  PAUSES/SLOWS THINGS DOWN)

THE HUMAN NERVOUS SYSTEM  REFLEXES (REFLEX ARCS)

THE HUMAN NERVOUS SYSTEM  SPECIALIZED SENSE RECEPTORS  WHAT ARE THE FIVE SENSES?  SIGHT  EYE  SOUND  EAR  TOUCH  SKIN  TASTE  TONGUE  SMELL  NOSE

THE HUMAN NERVOUS SYSTEM  EYE

THE HUMAN NERVOUS SYSTEM  EAR

THE HUMAN NERVOUS SYSTEM  SKIN

THE HUMAN NERVOUS SYSTEM  TONGUE

THE HUMAN NERVOUS SYSTEM  NOSE

THE HUMAN NERVOUS SYSTEM  THE NERVOUS SYSTEM IS ONLY HALF THE STORY…DON’T FORGET, REGULATION INCLUDES NERVOUS SYSTEM & ENDOCRINE SYSTEM  THE ENDOCRINE SYSTEM IS NEXT!!  HORMONES…OH YEA!!!
