apodeme of rostrum [FBbt_00051198]

Large part of cuticle within the rostrum (McKellar et al., 2020). One end (anterior-ventral) is attached to the external cuticle, forming the joint around which the rostrum rotates as it is extended and retracted (McKellar et al., 2020). Proboscis muscle 9 is attached to an arm dorsal to the joint and its contraction rotates the apodeme, pushing the posterior part of the apodeme (and the rostrum) ventrally away from the head cavity (McKellar et al., 2020).
