Each groove of each arm in turn has four rows of hollow tube feet that can be extended or withdrawn.Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray, known as an ambulacrum.chinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers.

EliteÂ® brackets and buccal tubes work as a system, moving the teeth in a combined effort, allowing you to achieve super Class I Molar Relationship. The distal buccal cusp of the upper 1st molar occludes with the mesial buccal cusp of the lower 2nd molar. Precise Root Angulation Each EliteÂ® bracket and buccal tube is engineered with precise angulation, placing the long axis of the root distal to the occlusal portion of the crown, allowing all roots to align parallel. Level Slot Line-up The base of each EliteÂ® bracket and buccal tube is anatomically contoured. This permits you to place the bracket with ease and
