Question

Which of the following statements is/are TRUE? No locally released from endothelial cells causes activation of cGMP signaling cascades in adjacent vascular smooth muscle cells NO is synthesized from the amino acid L-arginine NO can lead to inhibition of voltage-activated Ca^2+ channels in smooth muscle All of the above are true Which of the following are located in the medullary Nucleus of the Solitary Tract (NTS)? Sympathetic preganglionic fibers High pressure baroreceptor cells Low pressure baroreceptor cells Central neurons that receive synaptic input from baroreceptor cells and that play an integrative role in regulation of blood pressure and cardiovascular function All of the above

Explanation / Answer

49.All of the statements are true.

Nitric Oxide released from endothelial cells causes activation of cGMP signaling cascades in adjacent vascular smooth muscle cells. Nitric Oxide synthases are the family of enzyme catalysing the synthesis of NO from amino acid L-arginine. NO can lead to the inhibition of voltage activated Ca2+ channel in smooth muscle which result in muscle relaxation.
