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

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)
