“…Based on the embryological development of the spinal cord and vertebral column, dermatomes and myotomes are interconnected with each other through corresponding spinal nerves and the medulla spinalis (Stoffel, 2011; van Cranenburgh, 1990; Wancura‐Kampik & Fanghänel, 2009; Zohmann, 1991; Zohmann & Kasper, 1994). The spinal nerves follow the expansion of the growing body surface (DeLahunta & Glass, 2009) and represent the anatomical basis for interactive segmental reflex arcs (Kasper, 2011b; Nickel, Schummer, & Seiferle, 2003b; Wancura‐Kampik & Fanghänel, 2009; Zohmann, 1989). These relationships are widely used for diagnosis, therapies and anaesthesia (Kasper, 2011a, 2011b; Nickel, Schummer, & Seiferle, 2003a; Stoffel, 2011).…”
