  • 1. Construct Ch 9 Interactive NotesNeed 6 pages of binder paperOn cover, write• Chapter 9: Sensory System• Name, Period, Seat number• A color pictureNumber pages: First lined page = 1
  • 2. Touch(pg 2)
  • 3. Types of Sense ReceptorsReceptor Stimulus Examples
  • 4. Types of Sense ReceptorsReceptor Stimulus ExamplesChemoreceptors Chemical Taste and smell concentration
  • 5. Types of Sense ReceptorsReceptor Stimulus ExamplesChemoreceptors Chemical Taste and smell concentrationMechanoreceptors Pressure or Hearing and movement of fluids equilibrium
  • 6. Types of Sense ReceptorsReceptor Stimulus ExamplesChemoreceptors Chemical Taste and smell concentrationMechanoreceptors Pressure or Hearing and movement of fluids equilibriumNociceptors Tissue damage Pain receptors
  • 7. Types of Sense ReceptorsReceptor Stimulus ExamplesChemoreceptors Chemical Taste and smell concentrationMechanoreceptors Pressure or Hearing and movement of fluids equilibriumNociceptors Tissue damage Pain receptorsThermoreceptors Temperature Heat and cold receptors
  • 8. Types of Sense ReceptorsReceptor Stimulus ExamplesChemoreceptors Chemical Taste and smell concentrationMechanoreceptors Pressure or Hearing and movement of fluids equilibriumNociceptors Tissue damage Pain receptorsThermoreceptors Temperature Heat and cold receptorsPhotoreceptors Light Vision
  • 9. General Senses• Widely distributed throughout the body
  • 10. General Senses• Widely distributed throughout the body• Touch, pressure, proprioception, temperature, pain
  • 11. Touch and Pressure• Receptors are in the skin
  • 12. Touch and Pressure• Receptors are in the skin• Free nerve endings: located in epidermis. Sense clothing
  • 13. Touch and Pressure• Receptors are in the skin• Free nerve endings: located in epidermis. Sense clothing• Meissner’scorpsucles: located in dermal papillae. Sense light touch
  • 14. Touch and Pressure• Receptors are in the skin• Free nerve endings: located in epidermis. Sense clothing• Meissner’scorpsucles: located in dermal papillae. Sense light touch• Pacinian (lamellated) corpsucles: located deep in dermis. Sense heavy pressure
  • 15. Proprioception• Senses the location and movement of body parts
  • 16. Proprioception• Senses the location and movement of body parts• Golgi tendon organs: found at the junction of tendons and muscles
  • 17. Temperature• 10 times as many cold receptors as heat receptors
  • 18. Temperature• 10 times as many cold receptors as heat receptors• Extreme temperatures stimulate pain receptors (nociceptors)
