  1. Nervous System Group Members: Claudia Caballero Elio de Gracia Erick Beteta Exavier Castrellón Emma Ramos Juan Poveda

  2. Objectives:

  3. Nervous system is the chief controlling and coordinating system of the body. It controls and regulates all voluntary and involuntary activities of human body. There are three characteristic properties of nervous system of human body: Sensitivity, Conductivity and Responsiveness INTRODUCTION

  4. CONTENT • Unit of NervousSystem • NervousSystem • Function • Central NervousSystem • Interesting Facts • Main parts • Division • PeripheralNervousSystem • Encephalon • Spinal Cord • Sense Organs • Autonomic NervousSystem SomaticNervousSystem • Cranial and SpinalNerves • ParasymphateticNervousSystem • SympatheticNervousSystem

  5. NEURON IS THE UNIT OF NERVOUS SYSTEM:

  6. Functions of the Nervous System • Control • Regulate • Communicate • Mental activity center: • Learning • Memory • Homeostasis

  7. Main Parts of the Nervous System • The nervous system is made of: • The encephalon **The nerves • The spinal cord The senses

  8. Nervous System is divided in:

  9. Central Nervous System • The Central Nervous System controls everything in the body. • It contains the nerves of the encephalon and spinal cord

  10. Encephalon

  11. General Division of the encephalon The Encephalon has three main parts: 1. The Cerebrum 2. The Cerebellum 3. The Brainstem

  12. The Cerebrum • The Cerebrum is the largest part of the encephalon. • It identifies the information gathered by your sense organs. • It is protected by the skull • The cerebrum controls yours: • Thinking • Memory • Speaking • Movements

  13. Areas and lobs of thecerebrum

  14. TheCerebellum The cerebellum is below and to the back of the cerebrum. The cerebellum controls your: Balance Posture

  15. THE BRAINSTEM

  16. The Spinal Cord The spinal cord sends messages to the brain. The spinal cord is the part of the nervous system that connects the brain to the rest of the nervous system.

  17. PeripheralNervousSystem

  18. PeripheralNervousSystem controls

  19. Cranial nerves

  20. Somatic Nervous System

  21. Sensory neurons

  22. Motor neuron

  23. interneuron or Mixed neuron Carry impulses from sensory nerves to motor nerves.

  24. Spinal Nerves

  25. Peripheral NervousSystem The peripheral nervous system is made of the senses organs, those organs are:

  26. Theeye

  27. Vision

  28. Ear and Hearing

  29. Skin and Touch

  30. Thenose and Smell

  31. Mouth and TASTE

  32. Autonomic Nervous System

  33. Parasympatheticbrings things back to normal

  34. INTERESTING FACTS  About how many neurons are in the human brain? 100 billion About how many neurons are in the spinal cord? 1 billion How long do you think the longest axon in the world is? Around 15 feet

  36. THANK YOU 
