  1. 1. Physiological Bases of Human Behavior The Nervous System
  2. 2. Eyes Vision Nose Olfaction Receptors Sense Organ Ears Audition Tongue Gustation Skin Tactile Effectors Muscles and Glands Connectors Nervous System
  3. 3. 1. To gather and Process Information. 2. Produce responses to stimuli. Coordinate the working of the different cells. Function and Purpose of Nervous System
  4. 4. Nervous System
  5. 5. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS)
  6. 6. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS) Spinal Brain Cord
  7. 7. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS) Spinal Brain Cord Hemispheric Core of the brain
  8. 8. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS) Spinal Somatic Autonomic Brain Cord Nervous System Nervous System Hemispheric Core of the brain
  9. 9. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS) Spinal Somatic Autonomic Brain Cord Nervous System Nervous System Sympathetic Parasympathetic Hemispheric Nervous System Nervous System Core of the brain
  10. 10. CENTRAL NERVOUS SYSTEM
  11. 11. CENTRAL NERVOUS SYSTEM
  12. 12. CENTRAL NERVOUS SYSTEM Brain Spinal Cord
  13. 13. Spinal Cord
  14. 14. Spinal Cord A cordlike neural structure encased in the backbone that serves as a pathway for afferent & efferent messages. It is also the connection center for reflexes.
  15. 15. Reflex/es Simple inborn automatic responses of some parts of the body Reflex Babinski Refl Pu pillary ex Moro / Startle Reflex
  16. 16. If Spinal Cord is damaged....
  17. 17. The Human Brain
  18. 18. The Human Brain The part of the CNS that lies within the skull. It is the decision maker, the central processor, and the interpreter of stimuli. Controls our thoughts, emotions and motivation.
  19. 19. Hemispheric Specialization
  20. 20. PRINCIPAL SECTIONS OF THE BRAIN
  21. 21. PRINCIPAL SECTIONS OF THE BRAIN Hindbrain Midbrain Forebrain
  22. 22. The Hindbrain THE SECTION OF THE BRAIN CLOSEST TO THE SPINAL CORD. IT IS RESPONSIBLE FOR THE BASIC LIFE PROCESSES, LIKE BREATHING, HEART RATE, AND TEMPERATURE.
  23. 23. M I D B R A IT IS LOCATED JUST ABOVE THE HINDBRAIN. IT I IS RESPONSIBLE IN CONNECTING THE CEREBRUM WITH THE BRAINSTEM AND THE N SPINAL CORD.
  24. 24. Serves as the connecting link between hindbrain and forebrain and have a special role in visual and auditory activities. Midbrain
  25. 25. THE LARGEST AND THE MOST COMPLEX PART OF THE HUMAN BRAIN. IT IS RESPONSIBLE FOR THE INTERPRETATION, DECISION MAKING, AND OTHER HIGHER MENTAL FUNCTIONS.
  26. 26. Main Parts of Forebrain
  27. 27. Thalamus THE MAJOR SWITCHING POINT IN THE HUMAN BRAIN.
  28. 28. Limbic System Hippocampus Pituitary Gland Amygdala Hypothalamus
  29. 29. Cortex CORTEX – The biggest part of the forebrain. It is divided into four (4) lobes. Frontal Lobe Parietal Lobe Temporal Lobe Occipital Lobe
  30. 30. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS) Spinal Somatic Autonomic Brain Cord Nervous System Nervous System Sympathetic Parasympathetic Hemispheric Nervous System Nervous System Core of the brain
  31. 31. Peripheral Nervous System
  32. 32. SOMATIC NERVOUS SYSTEM : In-charge in controlling voluntary muscles. AUTONOMIC NERVOUS SYSTEM: In-charge in activating involuntary systems.
  33. 33. Somatic Nervous System
  34. 34. Voluntary Muscles Activated when we’re moving or in motion
  35. 35. Autonomic Nervous System
  36. 36. Involuntarily Automatically activated without a person conscious control
  37. 37. Nervous System Central Nervous System Peripheral Nervous System (CNS) (PNS) Spinal Somatic Autonomic Brain Cord Nervous System Nervous System Sympathetic Parasympathetic Hemispheric Nervous System Nervous System Core of the brain
  38. 38. Parasympathetic vs. Sympathetic Nervous System
  39. 39. Sympathetic Nervous System Activated during emergency or stressful situation.
  40. 40. Parasympathetic Nervous System Conserves energy Operates in relax state
