Question: F. Matthias Alexander developed an ability that avoided what negative bodily issue?
Context: Johann Alexander Ecker (10 July 1816 – 20 May 1887) was a German anthropologist and anatomist born in Freiburg im Breisgau.  He was the son of Johann Matthias Alexander Ecker (1766–1829), a professor at the University of Freiburg. Matthias Media is an award winning Australian evangelical Christian publisher.  The business grew out of the ministry of Phillip Jensen and Tony Payne at St Matthias, Centennial Park, Sydney under the name St Matthias Press and Tapes.  Many resources now published by Matthias Media were developed as part of the ministry of Campus Bible Study at the University of New South Wales.  Since then the company has grown under the banner "Resources for growing Christians" and is now incorporated as a non-profit company under the name Matthias Media.  Distribution in the UK is through an independent partner organisation and in recent years a US office has been opened (Matthias Media (USA)). Nu is a central idea in the culture of the Hua people.  There is a relationship or connection between food, consumer, and a source.  According to their beliefs, all food contains the Nu of its creator or producer, with the exception of wild plants and vegetation.  "In Hua thinking, Nu is a highly volatile and nonstatic substance that is always in motion.  Nu is passed directly from person to person not only through intentional acts but also through unintentional acts.  Furthermore, all food transactions involve transfers and exchanges of "Nu" (Meigs, 1997 p. 99).  Nu is contained within bodily fluids, bodily substances, and any bodily product.  It can take a positive or negative effect on the people surrounding it, leading to exceptional growth and health, or contributing to a lack of growth and health.  Social relationships are also influenced by the substance of Nu. R v Brown [1994] 1 AC 212 is a House of Lords judgment in which a group of men were convicted for their involvement in consensual sadomasochistic sexual acts over a 10-year period.  They were convicted of "unlawful and malicious wounding" and "assault occasioning actual bodily harm" contrary to sections 20 and 47 of the Offences against the Person Act 1861.  The key issue facing the Court was whether consent was a valid defence to assault in these circumstances, to which the Court answered in the negative. The Alexander Technique (A.T.), named after Frederick Matthias Alexander, is an educational process that attempts to develop the ability to avoid unnecessary muscular tension by retraining physical movement reactions.  Alexander believed the individual's spatial self-awareness was related to psychological conditioning; questionably trained foundation habits of posture can be unsuitably added into procedural skills.  Alexander observed that those whose goals justified it necessary to have trained themselves to overcompensate could not trust their judgment of physical orientation and required effort, (their "sensory appreciation.") . Matthias Alexander Castrén (2 December 1813– 7 May 1852) was a Finnish ethnologist and philologist who was a pioneer in the study of the Finnic languages.  He was an educator, author and linguist at the University of Helsinki.  Castrén is best known for his research in the linguistics and ethnography of the Finno-Ugric and Samoyedic peoples. Matthias Alexander Rath (born 2 August 1984) is a German dressage rider.  Representing Germany, he competed at the 2010 World Equestrian Games and at three European Dressage Championships (in 2009, 2011 and 2015). The sympathoadrenal system is a physiological connection between the sympathetic nervous system and the adrenal medulla and is crucial in an organism’s physiological response to outside stimuli.  When the body receives sensory information, the sympathetic nervous system sends a signal to preganglionic nerve fibers, which activate the adrenal medulla through acetylcholine.  Once activated, norepinephrine and epinephrine are released directly into the blood by postganglionic nerve fibers where they act as the bodily mechanism for "fight-or-flight" responses.  Because of this, the sympathoadrenal system plays a large role in maintaining glucose levels, sodium levels, blood pressure, and various other metabolic pathways that couple with bodily responses to the environment.  During numerous diseased states, such as hypoglycemia or even stress, the body’s metabolic processes are skewed.  The sympathoadrenal system works to return the body to homeostasis through the activation or inactivation of the adrenal gland.  However, more severe disorders of the sympathoadrenal system such as phaeochromocytoma (a tumor on the adrenal medulla) can affect the body’s ability to maintain a homeostatic state.  In such cases, curative agents such as adrenergic agonists and antagonists are used to modify epinephrine and norepinephrine levels released by the adrenal medulla. Matthias Alexander Kristian Zimmermann (* 6 May 1981 in Basel) is a painter and new media artist from Switzerland. Frederick Matthias Alexander (20 January 1869 – 10 October 1955) was an Australian actor who developed the Alexander Technique, an educational process applied to recognize and overcome reactive, habitual limitations in movement and thinking.
