View the article PDF and any associated supplements and figures for a period of 48 hours. 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. The thoracic (rib) cage is well developed, and the sternum bears a pronounced keel for the attachment of the pectoral muscles, which move the flippers.

How are the bones of the frog, bird, and cat hindlimb similar? Hindlimb. Here we provide the first detailed description, based on immunohistochemistry and dissections, of the limb muscle development in the direct developing frog Eleutherodactylus coqui. It is a short, stout and cylindrical bone with a slightly curved shaft. This is accompanied by a body morphology particularly adapted to movement in a liquid medium. Sexual dimorphism in limb muscles is widespread among anurans, with males having stronger limbs than females. Please enable it to take advantage of the complete set of features! Frogs with forelimb landing radiated into many forms, locomotor modes, habitats, and niches with controlled landing thought to improve escape behavior. radio-ulna Located between the humerus and the metacarpus, the radius and the ulna fuse to form one long bone.

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. the fore ‐ and hindlimbs of a frog species exhibiting a direct. 2009), but gave no information on the physical properties of d … HHS Here, we provide confirmation of a similar system of “modular” output in nonhuman primates. In the latter case, the frogs performed a cartwheel around the stick, while they were only attached by their adhesive toe pads.
