Mesenteric Artery Contraction and Relaxation Studies Using Automated Wire Myography
Published on: September 22, 2011
Abstract:
Nothing is known of transduction mechanisms of baroreceptors in vivo. Not even the site of transduction is known. However, there are mechanotransducer ion channels that provide a useful model system of transduction. In these channels, transduction is accomplished by a strain-dependent increase in the probability of being open. Membrane tension is coupled to the channel by cytoskeletal strands that concentrate the strain energy from a large (approximately equal to 4000 A diameter) area of membrane and thereby provide high sensitivity. The channel is fast and does not inactivate, but viscoelastic coupling to the channel can dramatically alter the transfer function.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
