The action potential Retin-a generic Action potential (AP) occurs in the membranes of excitable cells under the influence of the stimulus threshold or subthreshold values ??which increases the permeability of the membrane to sodium ions. The sodium ions begin to enter into the cell, resulting in a decrease in membrane potential - membrane depolarization. With decreasing magnetic field to a critical level of depolarization opens voltage-gated sodium channels and membrane permeability for these ions increases 500raz (exceeding the permeability to potassium ions in the 20 times). As a result, the penetration of sodium ions in the cytoplasm and their interaction with the anions on the membrane potential difference disappears, and then there is recharge of the cell membrane (the inversion charge overshoot) - inner membrane surface becomes positively charged relative to the exterior (30 - 50 mV), then closed sodium channels and voltage-gated potassium channels open. As a result, the output of potassium from the cells begin the process of restoring the original level of the resting membrane potential - the membrane repolarization. If xenical generic such an increase in conductivity to prevent the introduction of potassium tetraethylammonium, which selectively blocks the potassium channels of the membrane repolyarizuetsya much slower. Sodium channels can be blocked by tetrodotoxin and unlock the subsequent introduction of the enzyme pronase, which breaks down proteins.

seanVinyasa Flow Asana Sequencing

This workshop will focus on integrating poses that smoothly move from one to another in creative sequences to create a graceful flow. We will take a journey together through a joyous and intense series cultivating prana and riding the wave of the conscious breath. Be prepared to have fun and challenge yourself!

Intermediate Level Class-assumes a working knowledge of asanas and dynamics and a regular practice but enthusiastic beginners are quite welcome.


A 40-year Sedona resident, Sean began his yoga journey in 2000, a wonderful way to enter the new millennium. After two years of Bikram Yoga he discovered the joys of Astanga Yoga and received his yoga teacher training at Devi Yoga in 2003 from the sister and brother team of Sonali & Nathan Ganghadeen: he then taught at the studio until 2010, weaving the tapestry of breath and motion of Astanga-based Vinyasa flow he continues to teach and practice today. Sean has participated in an ongoing education, attending yoga events and workshops with many great teachers. Keeping the fundamental aspect of the science of stilling the mind as the foundation and purpose of yoga in his classes, he offers a serious yet lighthearted interlacing of fun and challenging poses while keeping a strong focus on breath control and the inner practice.
