Transverse section and perspective view of a generalized arm (soft tissues and spines removed); note the arched ambulacral ossicles forming the ambulacral groove and the dorsal podial pores between ambulacral ossicles. One podium (tubefoot)
on the left is drawn in outline only to illustrate how the podia descend through the podial pores.
