Žup-Vëtiš-Ëtavú

The Žup-Vëtiš-Ëtavú is one of two rings (the other being the Žup-Vëtiš-Ŋüžtú) that bind the two sets of muscles (the Mëta-Garo and the Mëta-Matapëž) and control their acitivity. The Žup-Vëtiš-Ëtavú is the only one of the two rings that moves, and its movement decides which of the two muscle sets are active (able to freely control the leg's movements) and which are inactive (contributing mainly to the stability and structure of the leg). This alternation of the legs then causes the Týk, or foot, to change form, with the inactive muscle system being the main controller behind the movements of the foot in their respective forms.
