Banting, Best, Macleod and Collip discovered Correct Answers
Insulin
Baroreceptor reflex mechanism - effect on parasympathetic
Correct Answers 1) NTS extends to nAmb
2) nAmb has parasympathetic signals; increased via
baroreceptor signalling
Baroreceptor reflex mechanism - effect on sympathetic Correct
Answers 1) Afferent fibres end in NTS (nucleus of tractus
solitaries)
2) Neurons extend to CVLM (caudal ventrolateral medulla)
3) CVLM secretes GABA and inhibits RVLM
4) Inhibited RVLM decreases sympathetic signalling to IML
Baroreceptor stimulus Correct Answers Stretching of blood
vessels due to increased blood pressure
