Myofibrillar Protein Composition Of Regenerating And Pristine Claw Closer Muscles Of The Yabby, Cherax Albidis, Lanelle Cutler

Theses : Honours

Yabbies have the ability to regenerate lost limbs. Loss of a limb results in the growth of a limb bud. Development of this new limb involves many developing stages until the new limb becomes morphologically and physiologically virtually indistinguishable from its predecessor. In the yabby, the claw becomes functional after the first moult when the dactyl becomes moveable. However, the muscle fibres are able to develop force and appear to be functioning before the dactyl becomes moveable and the claw is operational (West et al., 1995). This study aimed to document morphological stages of claw regeneration and determine sequence and …
