  1. Senses with receptors widely distributed throughout the body, including skin, various organs, and joints.
    General Senses
  2. Senses with more specialized receptors confined to structures in the head, such as the eyes and ears.
    Special Senses
  3. Explain the difference between general and special senses.
    General senses are found throughout the body, and special senses are found only in the head, and have more specialized receptors.
  4. List the 5 types of sensory receptors.
    1) Chemoreceptors 2) Pain Receptors 3) Thermoreceptors 4) Mechanoreceptors 5) Photoreceptors
  5. What type of sensory receptor responds to changes in the concentration of chemicals?
    Chemoreceptors
  6. What type of sensory receptor responds to tissue damage?
    Pain Receptors
  7. What type of sensory receptor responds to temperature change?
    Thermoreceptors
  8. What type of sensory receptor has several types and responds to mechanical forces by detecting changes that deform the receptors?
    Mechanoreceptors
  9. What type of mechanoreceptor responds to changes in the tensions of muscles and tendons?
    Proprioceptors
  10. What type of mechanoreceptor responds to changes in blood pressure?
    Baroreceptors
  11. What type of mechanoreceptor responds to inflation of the lungs?
    Stretch Receptors
  12. What type of sensory receptor responds to light energy intensity in the eyes?
    Photoreceptors
  13. Occurs when sensory neurons reach threshold and the resulting action potentials cause the brain to become aware of that sensory event.
    Sensation
  14. Occurs when the brain interprets sensory impulses; is formed by the cerebral cortex.
    Perception
  15. Occurs when the cerebral cortex interprets a sensation to seem to come from the receptors being stimulated, and the brain projects the sensation back to its apparent source.
    Projection
  16. The ability to ignore unimportant stimuli. (ex: not thinking about background noise in a room)
    Sensory Adaptation
  17. Name the three groups of general senses.
    1) Exteroreceptive 2) Visceroreceptive 3) Proprioreceptive
  18. Type of general senses associated with changes at the body surface; include senses of touch, pressure, temperature, and pain.
    Exteroreceptive Senses
  19. Type of general senses associated with changes in viscera.
    Visceroreceptive Senses
  20. Type of general senses associated with changes in muscles and tendons and in body position.
    Proprioreceptive Senses
  21. Name the three touch and pressure receptors.
    1) Free Nerve Endings 2) Meissner’s Corpuscles 3) Pacinian Corpuscles
  22. Type of touch and pressure receptors found in epithelial tissues; responsible for the sensation of itching.
    Free Nerve Endings
  23. Type of touch and pressure receptors located in hairless portions of skin; involved in fine touch, as in distinguishing between two points on the skin.
    Meissner’s Corpuscles
  24. Type of touch and pressure receptors located in deep subcutaneous tissues of some body parts; associated with heavier pressure, stretch, and vibrations.
    Pacinian Corpuscles
  25. Type of temperature receptors that respond to temperatures between 77° F and 113° F.
    Warm Receptors
  26. Type of temperature receptors that respond to temperatures between 50° F and 68° F.
    Cold Receptors
  27. Type of pain in organs resulting from the stimulation of mechanoreceptors and decreased blood flow with lower tissue oxygen levels and accumulation of pain stimulating chemicals.
    Visceral Pain
  28. Type of pain in which visceral pain may feel as if it is coming from some part of the body other than the part being stimulated; derived from common nerve pathways (ex: a heart attack may cause pain in the left shoulder).
    Referred Pain
  29. Pain fibers that are myelinated; conduct impulses rapidly; associated with the sensation of sharp pain; sensed as coming from the surface.
    Acute Pain Fibers
  30. Pain fibers that are unmyelinated; conduct impulses slowly; associated with dull, aching pain sensations; felt in deeper tissues and skin.
    Chronic Pain Fibers
