Talk:Mahaim fibers

Mahaim fibers appear to apply parasympathetic influence to the myocardium to the same yet opposed extent that Purkinge fibers apply sympathetic influence. Purkinge fibers are regionally limited in electrical perfusion of the myocardium by the cardiac collagen skeleton. Purkinges' tree serves sympathetic, forward electrical polarization of the heart and is initiated by the sinoatrial node. Mahaims' tree appears to be limited to parasympathetic, backward electrical repolarization of the heart, histologically limited by collagen support structure between chambers. The Mahaim tree is initiated by the brain via the Vagus nerve and Spinal Accessory Ganglia. Prior depiction of the Paraspecific fibers of Mahaim Netter, et. al. suggest a robust parasympathetic electrical influence in diastole that induces suction of blood into the heart.--lbeben 01:45, 22 November 2008 (UTC)
