Understanding Samaana Vaata in relation to the physiology of digestion

Abstract

Ayurveda is a way of life governed by the principle that whatever there is in the universe is there in the body also. The concept of Tridosha is one such theory which decides the well-being and the diseased condition of a human being. That is, when in equilibrium leads to health and when vitiated, leads to disease. Vaata being one of the Tridosha leads the other two Dosha, Mala, Dhatus as the wind carries the clouds in the sky. There are five types of Vaata, i.e., Prana, Udana, Samana, Vyana and Apana. Samaana, is situated near Jatharagni and moves all over the Koshta. The function of Samaana Vaata can be corelated with functions such as Grahana, Pachana, Vivechana, Munchana. The myenteric plexus, or plexus of Auerbach, is located between the longitudinal and circular smooth muscle layers of the muscularis in gastrointestinal tract. The motor neurons of these plexus mostly control GI tract motility (movement), particularly the frequency and strength of contraction of the muscularis. This can be co-related to Karma of Samana Vata like Grahana, Munchana. The submucosal plexus, also known as Meissner’s plexus, is a network of autonomic motor nerve fibres located in the submucosa of the gastrointestinal tract. The motor neurons of the submucosal plexus supply the secretory cells of the mucosal epithelium, controlling the secretions and absorption of the organs of the gastrointestinal tract. This can be co-related to Karma of Samana Vaata like Pachana, Vivechana. Hence this article is aimed at further exploration of these anatomical and physiological aspects.
