... changing terrains or responding to a sudden change in body mass and orientation. Lizards such as the leopard gecko ( Eublepharis macularius ) employ autotomy – a voluntary detachment of a portion of the tail – to escape predation. Tail autotomy represents a natural form of significant (and localized) mass...

..., muscles must also respond to morphological changes, such as those that occur with tail autotomy in lizards. Tail autotomy in leopard geckos ( Eublepharis macularius ) results in a 25% loss of caudal mass and significant kinematic alterations to maintain stability. To elucidate how motor control...

... in the chela with stronger closing force. With loss of the right chela (autotomy), handedness transitioned from the right to left chela, and all crabs were left-handed thereafter. Reversed handedness was accompanied with a reduction of size and closing force in the regenerated right chela, and growth...

... the primary source of MIH, or by multiple leg autotomy (MLA). In our work on Carcinus maenas , however, ESA has limited effects on hemolymph ecdysteroid titers and animals remain in intermolt at 7 days post-ESA, suggesting that adults are refractory to molt induction techniques. Consequently, the effects...

... either chronically via corticosterone implants or relatively acutely via autotomy, were sham manipulated or were left unmanipulated. Both stressors resulted in elevations in corticosterone within physiologically relevant levels, though the implants resulted in significantly higher levels than did...

... mediated destabilisation of ligament fibres at a particular syzygy. The aim of this investigation was to identify neurotransmitters that are involved in the autotomy response. Physiological experiments were conducted on isolated preparations of syzygial joints, which can be induced to undergo autotomy-like...

... muscles when molting was induced by either eyestalk ablation (ESA) or multiple limb autotomy (MLA). However, the effect of molt induction was greater in the claw muscle. By late premolt, Gl-Mstn mRNA in the claw muscle decreased 81% and 94% in ESA and MLA animals, respectively, and was negatively...

...Gary B. Gillis; Lauren A. Bonvini; Duncan J. Irschick SUMMARY Voluntary loss of an appendage, or autotomy, is a remarkable behavior that is widespread among many arthropods and lower vertebrates. Its immediate benefit, generally escape from a predator, is balanced by various costs,including...

..., and they are therefore lost, along with the limb, upon autotomy, leaving the severed, distal axonal stumps of the sensory neurons within the ganglionic root. During the regeneration of a limb, new sensory neurons develop within the limb, and their axons must then grow into the ganglionic root to make the appropriate...

.... Moreover, our experiments suggest that cell C activity is strongly involved in the onset and the maintenance of swimming behaviour. Swimming can be altered by autotomy of legs on one side performed a few days in advance, and leads to the same turning tendency as does contralateral cutting of a connective...

...Maria Byrne ABSTRACT The stimuli provoking evisceration of Eupentacta quinquesemita (Selenka) and autotomy of isolated pharyngeal retractor muscle (PRM) tendons were investigated. Tendon autotomy is a two-part response involving PRM contraction and breakdown of tendon connective tissue...

...U. Bässler ABSTRACT Autotomized legs of the stick insect Cuniculina impigra bend rapidly and rhythmically at the femur-tibia joint. These flexions occur at a frequency of 1–6 Hz immediately after autotomy and decrease in frequency and amplitude with time. Each flexion is produced by a burst of 1–14...
