ANSWERS
◉ Neurotransmitters Involved in Sleep/Wake Switch. Answer:
Histamine from the TMN
GABA from the VLPO
◉ A-beta fibers. Answer: Detect small movements, light touch, hair
movement, and vibrations
(Non-noxious)
◉ C fibers. Answer: Bare nerve endings only stimulated by noxious
mechanical, thermal, or chemical stimuli
C=chemical
◉ A delta fibers. Answer: Senses noxious mechanical stimuli and
subnoxious thermal stimuli
◉ Peripheral Neuropathy pain. Answer: Damage to/dysfunction of
peripheral nervous system.
, Responds to peripherally and centrally acting drugs, NSAIDs and
opioids.
Ex: diabetic neuropathy, post herpetic neuralgia
◉ Pathophysiology of chronic pain. Answer: Chronic pain results from
changes in sensitivity in both ascending and descending (PGA, RVM,
DLPT) pathways.
Can lead to grey matter loss and central sensitization.
Can be inflammatory or degenerative in nature.
Peripheral, can become centralized, or mixture of both.
◉ Medications for falling asleep. Answer: Need medications with short
half life
Ramelteon
Roserem
Sonata (middle insomnia, need 4 hours to dedicate)
