A: oxygen mediated smooth muscle contraction


REPEAT: Baroreceptors found everywhere except:

A: Carotid body


REPEAT CV84 Comparing the aorta and radial artery: (same options as prev)


REPEAT CV26 During increased intrathoracic pressure of Valsalva manoeuvre:

Renal Physiology

Actions of ADH in the kidney:

A:
B: something about collecting ducts
C: increase aquaporins in basolateral surface
D: cause vasoconstriction by actions on V1 (or?V2) receptors
E:


REPEAT MCQ-feb12-37 Actions of PTH on the kidney:

GI Physiology

A: tone is only due to smooth muscle
B: ?
C:
D:
E: tone increases when intragastric pressure increases

Blood & Immunology

NEW Platelets:

A: have a nucleus and granules (OR- A: have no nucleus but with granules)
B: something about half life in plasma (maybe 8-10 days)

Endocrine and Metabolism

Which of the following hormones is LEAST likely to be inotropic?

A: adrenal corticoids
B: adrenal medullary hormones
C: insulin
D: glucagon
E: thyroxine

Comment Genuinely horrible question. All five have inotropic effects. Insulin is the least likely however, as the experimental data for its inotropic effects were 1) primarily in vitro 2) variable between studies and hence, inconclusive.

Neurophysiology

Muscle and NMJ Physiology

Maternal, Fetal and Neonatal Physiology

Clinical Measurement

Question on impedance...capacitance...??


REPEAT MCQ-feb12-70 Absolute Humidity: same options as previously
