What is meant by the plasma concentration term mg%
how many mg in 100 ml
two factors are most critical to h2o balance across a cell's membrane?
blood pressure and plasma protein
awareness of phrase and nod of agreement
primary auditory area, primary motor area, general interpretive area
two neural activities are most related to the limbic system?
psychosomatic dysfunction, memory filling/fixation
three neural activities are functions of medulla oblongata?
swallowing reflexes, respiratory rhythm, memory filling/fixation
two neural activities are primarily function of thalamus?
sensory relay, memory retrieval
two neural areas are targets for destruction/damage in a person with Parkinson's disease/syndrome?
basal ganglia, substantia nigra
Which neural area is most likely damages/malfunctioning in people with with myasthenia gravis?
neuromuscular junctions
Which two neural areas are most likely malfunctioning in people suffering from epilepsy?
reticular activating system, cerebral cortex
Which three features are characteristic of Duchenne's muscular dystropy?
X-linked, missing/defective genetic material, childhood onset
1 mMol = 1 mEq
cholesterol and glucose
1mMol = 3 mOsm
CaCl2, FeCl2, ZnCl2
three factors most critical to water balance between cell fluid and tissue fluid compartments?
sodium, potassium, Na-K pump
three of the following do not freely filter from blood into renal nephrons?
antibody, basophil, clot factor VIII
three renal components are most critical to the bulk of a nephrons active reabsorption of chemicals?
proximal tubule, peritubular capillaries, carrier proteins
two factors determine the renal tubular load for a chemical?
glomerular filtration rate, its plasma concentration
three substances are continually recycled by the loop of Henle to create high osmotic pressure required for ADH action
sodium, urea, chloride
Which two activiities occur mostly in the nephron's distal tubule?
acid secretion, aldosterone action
Two major signs of early GN?
hematuria, proteinuria
nerve fibers controlling muscles used to clench your teeth in annoyance over vaguely written questions?
axons, dendrites
4 things to be annoyed and understand outburst?
primary auditory area, thalamus, general interpretative area, primary motor area
3 neural activities are primary functions of the medulla oblongata?
blood pressure regulation, swallowing reflex, respiratory rhythm
3 neural activities are primary functions of they hypothalmus?
hunger/thirst sensations, pituitary control, psychosomatic disturbance
two neural areas are targets for destruction/damage in a person with focal or generalized epilepsy?
cerebral cortex, reticular activating system
two neural areas are most likely damaged/malfunctioning in people with Parkinsn's disease?
substantia nigra, basal ganglia
which neural area is damaged/malfunctioning in a person with multiple sclerois?
myelin sheath
neural area is damaged/malfunctioning in a person with myasthenia gravis?
neuromuscular junctions
which 3 features are char. of Duchenne's muscular dystrophy?
X-linked genetic, missing/defective genetic material, childhood onset
Which two areas are most critical to a person's memory functions?
hippocampus and thalamus
Explain why the renal mechanism for acid-base reg. is more efficient than the resp. reg or blood pH
renal mech. controls bicarb seperately from H+, respiratory does both simulataneously
explain why its sig. that GFR normally does not flucturate as a persons BP changs
BP to low, and filtration dropped then toxicity would happen if BP to high, then filtration would put too much into urine (low glucose)
S/S of chronic renal failure
low levels solutes, polyuria, nocturia
S/S of end -stage renal failure
hyper electrolyes, BP, and electrolytes and wastes
por and cons of hemodialysis
very fast and accurate but must have a way of transp. to hosp
pros and cons of peritoneal dialysis?
slower results but can be done in home for the pt - allows for mobility
specific neural reflex in terms of stimulus
smack on patellar tendor received by muscle spindle
specific neural reflex of receptors/detectors
low BPis sensed by barro receptors
specific neural reflex of CNS level of control
spinal cord, vasomotor center is is middle of medulla oblongota
specific neural reflex of effectors and relex response
rectus femoris causes foot to kick out
two neurological S/S expectes in pt with hemorrhage of basilar artery
respiratory diff, and swallowing diff, low BP sleeplessness
two diag S.S of Parkinsons disease
resting tremors, bradykinesia and dyskinesia
diagram that shows what area of the body affected by spinal damage
specific psychosomatic respnse that occurs in people and discuss the brain regions which interact to produce affect
hypothalmus, sypathetic-heart related, parasymp - GI
difficulty in drug therapy for myasthenia gravis
inadequate drug therapy does not leave the neurotransmitters - excess drug therapy makes pt diff to brethe
tubular load
how much enters the tube
transport maximum
how fast the tubule filters substance
explain why a particular hormone is "most active" in a particular segment of nephron
receptor protein
cause for pyelonephritis
a drug is very concentrated or toxic
S.S of hemorrage in middle cerebral artery
hearing loss, loss of sensation
ADH in health function
prevents low BP, prevents excess urine from stopping heart
etiology and pathogenesis of GN
DM damaging to glomerules because of increased glucose
etiology and pathogenesis of pyelonephritis
drug toxicity
mechanisms to maintain constant blood flow to brain
increased or decreased BP
mechanisms to maintain distribution of blood to different parts of brain
arterioles based on activity level of oxygen
S/S pattern of recurring transient ischemic attacks from cerebrovascular
some as heart certain spots most damged leading to similar S/S in pt
S/S of embolism
no exception, different foreach person depends on size and local
two S/S of hemorrhage of basilar artery
uncontrolled BP, inability to swallow
two diagnostic S/S of multiple sclerosis
weaknes, clumbsiness
