Nervous system

  1. 1. GUIDED BY- PRESENTED BY-Dr. ARVIND SHUKLA SONIYA BARCHE
  2. 2.  INTRODUCTION NEURON CELL HUMAN NERVOUS SYSTEM CENTRAL NERVOUS SYSTEM PHERIPHERAL NERVOUS SYSTEM AUTONOMOUS NERVOUS SYSTEM FUNCTION OF NERVOUS SYSTEM CONCLUSION REFERENCES
  3. 3. INTRODUCTIONTHE SYSTEM WHICH RECEIVES THE STIMULUS,TRANSMITS IT TO THE OTHER PARTS OF THEBODY& THE CORRESPONDING EFFECTS ARESHOWN, ARE CALLED NERVOUS SYSTEM.IT CONSTITUTES ABOUT 2.4% OF TOTAL BODYWEIGHT.IT LINKS THE VARIOUS ORGANS & SYSTEM,CO-ORDINATES ALL THEIR ACTIVITIES & ENSURESTHE INTEGRITY OF THE ORGANISM.THE BRANCH OF BIOLOGY ,DEALS WITH THESTUDY OF NERVOUS SYSTEM CALLEDNEUROLOGY.
  4. 4. NEURON CELLSTRUCTURAL & FUNCTIONAL UNIT OFN.S.,HUMAN NERVOUS SYSTEM HAS ABOUT 100BILLION NEURONS.FULLY FORMED NEURONNEVER DIVIDE.NEURON IS COMPOSED OF MAINLY CYTON &PROCESS OF NEURON.THE REGION WHERE THE AXON OF ONE NEURONJOINS WITH THE DENDRITES OF ANOTHERNEURON IS CALLED AS SYNAPSE.DEPENDING UPON THE NO. OF PROCESSES THENEURONS ARE UNIPOLAR,BIPOLAR,MULTIPOLAR.

  6. 6. NERVOUS SYSTEM PERIPHARAL AUTONOMIC CENTRAL N.S. N.S. N.S. SYMPA- PARASYM- SPINAL CRANIAL SPINALBRAIN THETIC PATHETIC CORD NERVES NERVES N.S. N.S.
  7. 7. BRAIN-IT IS UPPER & BROADER PART LYING IN THE HEAD.IN ADULTS,IT WEIGHTS ABOUT 1400gm &HAS 100BILLION NEURON.THE BRAIN IS COVERED BY THREE MEMBRANOUS COVERING(OUTER DURA MATER,MIDDLE ARACHNOID,INNER PEAMATER) CALLED MENINGES.THE BRAIN FORMS ABOUT 98% OF THE WEIGHT OF WHOLEC.N.S.IT IS MADE UP OF FOLLOWING 3 PARTS-FORE BRAIN- CEREBRUM,DIENCEPHELON,OLFACTORY LOBEMID BRAIN - CEREBRAL PEDUCLE,CORPORA QUADRIGEMINAHINDBRAIN - CEREBELLUM,PONS,MEDULLA OBLONGATA
  8. 8. SPINALCORDLIKE BRAIN,SPINAL CORD IS ALSOSURROUNDED BY MENINGES THE SPACEBETWEEN THESE MEMBRANE IS FILLED WITHCEREBROSPINAL FLUIDTHE LENGTH OF SPINAL CORD IN HUMANMALES IS 45 CM AND IN FEMALE 43 CMTHE SPINAL CORD IS CONSIST OF CENTRALCANAL SURROUNDED BY A CENTRAL COREOF GARY MATTER.
  9. 9. Peripheral nervous system is formed of nerves extending between the central nervous system & receptor or effectors organs, having 2 types of nerves- Cranial nerves – 12 pairs, originating from brain& terminate at various effectors organ. spinal nerves –there are 31 pairs of spinal nerves which arise from the spinal cord.
  10. 10. AUTONOMOUS NERVOUS SYSTEMIT IS A SELF GOVERNING NERVOUS SYSTEM. IT HAS BOTH SENSORY & MOTOR NERVES.IT DISTINGUISHED INTO 2 SYSTEM- SYMPAHTATIC NERVOUS SYSTEM PARASYMPATHETIC NERVOUS SYSTEM
  11. 11. FUNCTIONIT REGULATES &CONTROLES THE VARIOUS ACTIVITIES OFTHE ORGAN & FINALLY THE ORGANISM AS A WHOLE.FOREX:SENSE OF VISION ,HEARING,MUSCULAR CONTRACTION,HEART BEAT.IT REGULATES THE INTERNAL ENVIRONMENT OF THEBODY BY COORDINATING THE WORKING OF THE VARIOUSGLANDS & TISSUES OF BODY.HELPS THE ORGANISM TO REACT TO THE EXTERNALENVIRONMENTAL CHANGES.STORES THE MEMORY OF THE PAST & PRESENTEXPERIENCES.PRODUCE SENSATION LIKEVISION,HEARING,TASTE,SMELLPLASURE & PAIN WITH HELP OF SENSE ORGANSATTACHED TO THEM.
  12. 12. CONCLUSIONIN A COMPLEX ORGANISM THE NERVOUSSYSTEN PLAYS THE LEADING ROLE INREGULATING ALL THE PHYSIOLOGICALPROCESSES & IN AFFECTING THE CONNECTIONSOF THE ORGANISM WITH THE EXTERNALENVIRONMENT.IT ALSO LINKS THE VARIOUS ORGAN & SYSTEM,COORDINATES ALL THEIR ACTIVITIES &ENSURES THE INTEGRITY OF THE ORGANISM.THE NERVOUS SYSTEM IS COMPOSED OFNERVOUS & THE GLIAL CELL.THE NERVOUS SYSTEM IS CONSIST OF THREEPARTS:-C.N.S.,P.N.S.,A.N.S..
