golgi organ in voluntary movement provides info to NS about a. lenght of muscle b velocity of movement c blood flow to muscle d tension developed e change in joint angle produced
d
which is false
a brain uses predominatly glucose
b 1 g fat produces 9 cal
c brain cannot use ketone bodies for energy
d ketone bodies can be used by many peripheral tissues
e lactate is a commonly utilized energy source
b
1 g fat produces 9kcal or 9Cal
BUT brain can use ketone bodies
which is false a CMRO2 brain 15ml/100g/min b raised bsl increases cerebral metab c metabolic state of brain assess useing jugular venous oxygen sat d at 27 degree brain CMRO2 halve e seizures increase CMRO2
a and b
3ml/100gm/min
17 normal anion gap acidosis a DKA b lactic acidosis c salicilate poisening d acetazolamide therapy e proglutamic acidosis
d
human bile has all except a cholic acid b chenodeoxycholic acid c deoxycholic acid d lithocholic acid e uric acid
e
resp rythm generated by a apneustic centre b nucleus parabrachialis c dorsal medulla d pneumotoxic centre e cerebrum
c
which is true
a viscosity of newtonian fluid increases with increase temp
b during laminar flow if the diameter of tube falved flow is reduced by factor of 8
c flow through ofrice, flow rate inversely proportional to square root of density
d a mix of helium 70% and oxygen 30% has lower viscosity than nitrogen 70% and oxygen 30%
e the flow through a rotameter are unaffected at altitude
e
which is true
a. right before vent systole each vent contains 250ml blood
b during vent sys 85% of blood ejected
c during first phase vent sys both semilunar and av valves closed
d atrial contraction accounts 35% of vent filling
e atrial contraction becomes increasinly important for vent filling during bradycardia
c
all need energy except a sodium out of nerve cells b calcium into SR c hydrogen into luman distal nephron d glucose into adipose e K into striated muscle
d
insulin deficiency causes everything but a loss of phosphate in urine b K moves out of cells c mg moves intracellularly d reduced plasma volume e lipolysis
a
principle hormone secreted by fetal adrenal cortex a. cortisol b coticosterone c dehydroepiandrosterone d progesterone e pregnenolone
a
when breath 100% O2 mixed venous O2 sat is a 25% b 50% C 75% d 85% e 100%
c
diabetes insipidus untreated for 4 hrs a Na 140 K 4 Osmol 280 b Na 130 K 3.5 osmol 300 c Na 140 K 4.5 osmol 320 d Na 155 K3.5 osmol 280 e Na 155 K 3.0 osmol 320
