  • 3. 
    Nociceptors respond to......

  • 4. 
    What are the 4 steps in the process of sensation?1.2.3.4.

  • 5. 
    Name and describe ALL receptors associated with the skin/touch.1. Free nerve ending = unspecific, simple. found throughout the body. pain, temp., itch, movement2. Touch= more complex  crude touch-- something has contacted skin  find touch- where, what, and texture (specific)

  • 6. 
     ------ TYPES OF TOUCH RECEPTORS ----Merkel disc=
    • A. 

      Light touch, superficial pressure, in epidermis, found on lips, fingertips, and hands

    • B. 

      In dermis, ligaments and tendons. found on hands and soles of feet. sensitve to stretching as digits and limbs are moved and continued pressure.

    • C. 

      Wide spread, dermis, subcutaenous, under mucous and serous membranes, joints. recognizes deep pressure and vibration. Associated with proprioception. pressure


  • 7. 
    --- TYPES OF TOUCH RECEPTORS ---Pacinian Corpuscles=
    • A. 

      Wide spread, dermis, subcutaenous, under mucous and serous membranes, joints. recognizes deep pressure and vibration. Associated with proprioception. pressure

    • B. 

      In dermis, ligaments and tendons. found on hands and soles of feet. sensitve to stretching as digits and limbs are moved and continued pressure.

    • C. 

      Light touch, superficial pressure, in epidermis, found on lips, fingertips, and hands


  • 8. 
    Explain thermal sensation.thermoreceptors- free nerve endings. warmth vs. coldness - different receptors. anything above or below stimulate pain receptors.

  • 9. 
    Explain painful sensation. Nociceptors- free nerve endings. everywhere except brain. extreme, thermal, mechanical, or chemical stimuli. tissue damage causes release of prostaglandins, kinins, and potassium ions. pain may persist because chemicals linger.
