UNMC Pathology Test 1 Questions And 100%Correct Answers
Fluids in the body include blood, serum, saline, albumin, urine, bile, hormones,
cerebrospinal fluid - Answer Fluids necessary for homeostasis
Peripheral pain receptor found in skin, - Answer Nociceptor
Hitting finger with hammer - Answer Noxious stimuli
Specialized sensory fibers, carry nociceptor impulse to spinal cord (A delta and C fibers
- Answer Afferent fibers
In back of spinal cord (dorsal horn) area with lots of potential modulation or changing of
impulses - Answer Substantia Gelatinosa
Key neurotransmitter peptide. For transmission of pain impulses to brain, substance p
must bind to receptors - Answer Substance P
Receptor which substance P binds to for the transmission of pain impulses to brain -
Answer Neurokinin 1
Conduct impulses rapidly. Trying to depolarize SG and T cells - A beta - Answer Large
Diameter fibers
have slower conduction on impulses, attempt to inhibit SG, but excite T (A delta and C) -
Small Diameter fibers
,Attempts to inhibit T cell, if more stimulated the more it will inhibit T - Substantia
Gelatinosa
Central Transmission cell, receives all input, the more excitation of the T, the more
perception of P - T cell
inhibition of S, stimulation of SG< inhibition of T - Answer L fibers STIMULATED closed
gate
inhibition of L, inhibition of SG, potentiation of T - Answer S fibers STIMULATED Open
gate
Concentrations and their ability to equalize - Answer Osmotic forces
Equal osmolarity between the ICF and ECF - Answer Homeostasis
Equal concentrations not equal volume - Answer Goal of fluid balance
FLuid will move from high to low, from ICF to ECF to dilute the ECF down, free moving
water not concentrations - Answer Addition of hypertonic solution
Free water from ECF into the cells to dilute and equal the cells - Answer Addition of
hypotonic solution
A solution with more solute particles than H20 molecules - Answer A more concentrated
solution would beB
NO. We can make water move though - Answer Can we add a hyper or hypo solution to
the ICF
, 40% of body weight, 28 L - Answer Intracellular Fluid ICF
20% of body weight, 14 L - Answer Extraceullar Fluid ECF
15% of body weight, 11L - Answer Interstital Fluid (ECF)
5% of body weight, 3 L - Answer Intravascular fluid (ECF)
60 % of body weight, 42 L - Answer Total Body water
(forces favoring filtration) - (forces opposing filtration) - Answer Net filtration formula
Fluid has to move out of capillaries, need to get O and nutrients into the cell. Need O and
byproducts of food into cell to carry out metabolism - Answer Net filtration
function to filter out fluid, - Answer Arteriole side of capillary
Capillary hydrostatic pressure and interstitial oncotic pressure - Answer Forces
promoting filtration fluid out
Capillary oncotic pressure, interstital hydrostatic pressure - Answer Forces opposing
filtration fluid in
Pressure or force OUT due to flow of fluid within the capillary, hydrant, strong pressure
out - Answer Capillary hydrostatic pressure
Osmotic pull created by large molecules in interstitial space, filtration out of capillary -
Answer Interstitial oncotic pressure
