a patient has extremely high blood pressure. what will this most likely lead to?
- increased capillary oncotic pressure leading to to filtration out of capillary
- increased capillary hydrostatic pressure leading to filtration out of capillary
- decreased interstitial oncotic pressure leading to fluid staying in the capillary
- increased interstitial hydrostatic pressure leading to filtration out of capillary -
ANSWER-b. increased capillary hydrostatic pressure leading to filtration out of capillary
a patient has major burns, causing increased capillary permeability, which is likely to occur?
- increased interstitial oncotic pressure
- decreased interstitial oncotic pressure
- increased capillary hydrostatic pressure
- increased capillary oncotic pressure - ANSWER-a. increased interstitial oncotic
pressure

true or false: afferent sensory fibers carry pain impulses from nociceptors to the brain - ANSWER-true
the ______ is a region in the dorsal spinal cord where modulation of pain impulses occurs
- afferent sensory region
- S and L fiber complex
- Substantia gelatinosa
- Central transmission (T) cell - ANSWER-c. substantia gelatinosa
regarding the Gate Control Theory of Pain, select the one FALSE statement 3 / 4
- L fibers stimulate (excite) BOTH the T cell and the SG
- S fibers inhibit BOTH the SG and the T cell
- The action of the SG is to inhibit the T cell
- The T cell collects all pain coming through this system - ANSWER-b. S fibers
inhibit BOTH the SG and the T cell
According to the Gate control theory of pain which would decrease pain perception?
- stimulation of S fibers
- stimulation of the T cell
- Inhibition of L fibers
- stimulation of SG - ANSWER-d. stimulation of SG
Which would increase pain perception?
- stimulation of S fibers leading to more stimulation of the T cell
- inhibition of S fibers leading to less stimulation of the SG
- inhibition of L fibers leading to less stimulation of the T cell
- Stimulation of L fibers leading to more stimulation of the SG - ANSWER-a.
stimulation of S fibers leading to more stimulation of T cell
