In the present study, we developed the initial musculotendon subsystem of a realistic model of the frog Rana pipiens . Previous work using an atomic force microscope in nanoindenter mode indicated that the outer, 10- to 15-μm thick, keratinised layer of tree frog toe pads has a modulus of elasticity equivalent to silicone rubber (5-15 MPa) (Scholz et al. A tree frog is a frog that can climb (or in the taxa of those that can). Characterizing forelimb and hindlimb movements may reveal interesting functional differences between Anolis ecomorphs. Here we provide the first detailed description, based on immunohistochemistry and dissections, of the limb muscle development in the direct developing frog Eleutherodactylus coqui. Frogs with forelimb landing radiated into many forms, locomotor modes, habitats, and niches with controlled landing thought to improve escape behavior. USA.gov.

Our observations and comparisons: (1) support the "in-out" developmental mechanism of the appendicular pectoral muscles; (2) show that the protractor pectoralis and its amniote derivatives trapezius and sternocleidomastoideus clearly develop, anatomically, from the branchial muscles; (3) corroborate that the similarity between the forearm/hand and the leg/foot muscles in tetrapods is due to derived homoplasic events that occurred during the fins-limbs transition and not due to serial homology; (4) lend some support for the hypothesis that the morphological transformation of the anuran tibiale and fibulare represents a distal shift in the zeugo-autopodial border; (5) provide evidence that the identity of the tetrapod hand and foot muscles is mainly related to the topological position of the digits to which they attach; and (6) for the first time, show that apart from a proximo-distal morphogenetic gradient there is also an ulno-radial/fibulo-tibial gradient within the development of the fore- and hindlimb muscles and a dorsoventral gradient within the ontogeny of the hindlimb (but not forelimb) muscles of the frog E. coqui; the two latter gradients are seen in the ontogeny of amniotes such as chickens but are markedly different to those seen in axolotl regeneration and ontogeny. In the latter case, the frogs performed a cartwheel around the stick, while they were only attached by their adhesive toe pads. Unlike the forelimb there is a firm bony union between hindlimb and trunk – left and right pelvic bones are joined in a pelvic girdle which is united with the vertebral column through strong sacroiliac joints situated caudomedial to the sacral tuberosities.
