Across
  1. 2. type of pathways that transmit info to many areas of the brainstem and cerebrum
  2. 5. sense of the functions and state of internal body organs
  3. 6. another word for somatosensation
  4. 8. this is when there is pain felt in one region of the body that is not the site of the injury
  5. 9. end of the peripheral neurons where somatosensory receptors are located
  6. 13. touch receptors that respond to mechanical deformation of the receptor
  7. 14. type of pathways that gives info about action and type of stimulation to cortex
  8. 15. the tract that is involved in pain stimuli commanding attention and interfering with sleep
  9. 16. what somatosensory receptors do with a stimulus when it changes it into an electrical signal
  10. 17. the number of receptors within a given area of body surface
  11. 18. type of touch that is light and associated with emotional bonding
  12. 20. type of receptors that are stimulated by physical deformation of the receptor itself or the surrounding area
  13. 21. the thalamic tract that is involved with tactile and proprioceptive input from the face
  14. 22. also known as fast adapting; when a receptor adapts quickly to stimulus and stops responding
  15. 23. pain receptors that are sensitive to stimuli that damage or can damage
  16. 25. the tract is involved in turning the eyes and head toward the source of noxious input
  17. 27. specialized mechanoreceptors located in the muscles, tendons, joints, and vestibular apparatus of the inner ear
  18. 28. chemical receptors that respond to substances released by cells
  19. 29. also known as slow adapting; when a receptor continues to fire during entire presentation of the stimulus
  20. 30. area of skin innervated by a single afferent neuron
  21. 31. sensory information from the skin and musculoskeletal systems
  22. 32. symptoms of this includes impair conscious proprioception and vibration, along with incoordination
Down
  1. 1. the type of neuron that is found on the first order neuron
  2. 3. type of regions that tend to have smaller diversity of receptors than distal regions
  3. 4. the area of skin innervated by axons from cell bodies in a single dorsal root
  4. 7. sense of direct interactions with the external world and its impact on the body
  5. 10. it’s functions include discriminative touch, vibration, and conscious proprioception
  6. 11. an aversive response to seemingly non-noxious tactile stimuli
  7. 12. type of pathways that bring unconscious proprioceptive and other movement-related information to the cerebellum
  8. 19. temperature receptors that respond to heat or cooling
  9. 24. type of touch that detects objects that contact skin and is associated with fine motor coordination
  10. 26. sense of one’s own body, involving sensation from muscles, joints, and tendons
  11. 31. the tract that is involved with emotions, personality, and movement
  12. 32. it’s functions include discriminative pain, discriminative temperature, and crude/coarse touch
