skeletal system of the frog?
541209
The frog skeletal system is divided into two regions the axial skeletal system and the appendicular system.\n\nThe axial skeleton consists of the skull, vertebral column, and sternum.\n\nThe appendicular system consists of the pectoral girdle, forelimbs, the pelvic girdle, and the hind limbs.\n\n1. Skull: 33 \n2. Middle ear: 2 \n3. Hyoid: 1 \n4. Vertebrae: 9 \n5. Urostyle: 1 \n6. Sternum: 1 \n7. Ribs: None 24\n8. Pectoral Girdle: 8 \n9. Forelimbs: 46 \n10. Pelvic Girdle: 6 \n11. Hind limbs: 52 \n12. Total Bones: 159

The axial skeleton forms the central axis of the body. It consists of the skull, the vertebral column, the ribs and the sternum or breastbone.  There are 80 bones total in the axial skeleton, and I'm sorry but I'm not going to type them all out for you.  I will, however, provide you with some links so that you can see what they are if you need to know all 80.  They have great diagrams.\n\nhttp://webschoolsolutions.com/patts/systems/skeleton.htm#axial\nhttp://www.botany.uwc.ac.za/sci_ed/grade10/manphys/axial.htm

none.  They are mollusks.  They do have those hard little beaks, but those are not bones any more than a bird's beak is a bone.

Yes it is. It has a backbone and internal skeleton (characteristics of vertebrates).  Plus it is a reptile..and all reptiles are vertebrates.

Your question does not make sense!\n\nFrog muscles are arranged like those in other vertebrates and will have similar names. For example your calf muscle is the gastrocnemius, it is the same in the frog and this is the tasty bit you might eat when served frogs legs.

The human skeleton is made of individual or joined bones (such as the skull), supported and supplemented by a structure of ligaments, tendons, muscles, cartilage and other organs.\n\nThe skeleton is not unchanging; it changes composition over a lifespan. Early in gestation, a fetus has no hard skeleton; bones form gradually during nine months in the womb. At birth, all bones will have formed, but a newborn baby has more bones than an adult. On average, an adult human has 206 bones (according to Gray's Anatomy, but the number can vary slightly from individual to individual), but a baby is born with approximately 300 bones. The difference comes from a number of small bones that fuse together during growth, such as the sacrum and coccyx of the vertebral column. An infant is born with pockets of cartilage between particular bones to allow further growth. The sacrum (the bone at the base of the spine) consists of five bones which are separated at birth but fuse together into a solid structure in later years. Growing is usually completed between ages 13 and 18, at which point the bones have no pockets of cartilage left to allow more growth.\n\nNot all bones are interconnected directly. There are 6 bones, the auditory ossicles (three on each side), in the middle ear that articulate only with each other. Another bone, the hyoid bone in the neck, does not touch any other bones in the body, and is supported by muscles and ligaments; it serves as the point of attachment for the tongue.Also some of the ribs called the floating ribs only hang by muscle and are not attached to the spine.\n\nThe longest and heaviest bone in the body is the femur and the smallest is the stapes bone in the middle ear. In an adult, the skeleton comprises around 20% of the total body weight.\n\nBones of the Head\n\n    * frontal bone\n    * mandible\n    * maxilla\n    * occiptal bone\n    * parietal bone\n    * temporal bone\n    * zygomatic bone \n\nBones of the Neck and Chest\n\n    * acromion\n    * atlas\n    * cervical vertebra\n    * clavicle\n    * false rib\n    * floating rib\n    * scapula\n    * spine of scapula\n    * sternum\n    * thoracic vertebra\n    * vertibral column \n\nBones of the Abdomen\n\n    * coccyx\n    * ilium\n    * ischium\n    * lumbar vertebra\n    * sacrum\n    * vertibral column \n\nBones of the Arm\n\n    * carpus (carpals)\n    * epicondyle\n    * epitrochlea\n    * head of humerus\n    * humerus\n    * metacarpus (metacarpals)\n    * olecranon\n    * phalanx (phalanges)\n    * radius\n    * ulna \n\nBones of the Leg\n\n    * calcaneus\n    * condyle of femur\n    * femur\n    * fibula\n    * head of femur\n    * metatarsus (metatarsals)\n    * neck of femur\n    * patella\n    * phalanx (phalanges)\n    * talus\n    * tarsus (tarsals)\n    * tibia

There is a family of frogs, the Pipidae (the Surinam frog genus Pipa, and the African clawed frog genus Xenopus) that lack a tongue. They are entirely aquatic and Xenopus is often sold as an aquarium pet.

All of the terrestrial vertebrates have four limbs (and thus, they are sometimes referred to as tetrapods, which literally means 'four feet').\n\nNot only that, but they all have the same basic structure of limb bones - pectoral girdle consisting of scapulae, with the humerus as the single upper arm bones, radius and ulna as the two lower arm bones and a wrist made up of carpal bones, followed by metacarpals and digits made up of phalanges.  The lower limb girdle is also nearly identical, with a pelvis, femurs, tibia/fibulla, tarsals, metatarsals and phalanges.\n\nThis incredible similarity of structure in limb bones between incredible diverse groups of organisms - chickens, frogs, salamanders, whales, lions, humans, seals, plesiosaurs, iguanas, horses, mice and platypus all have this same exact limb structure, is evidence that all of these organisms share a common ancestor that also had this limb arrangement.\n\nStrangely enough, the remaining vertebrate group, the fish, do not all share this limb bone arrangement.  Most of them have the same set-up of pectoral and pelvic limbs, but after that, there's a whole variety of totally different skeletal anatomy.\n\nThere is one group of fish that does have this limb arrangement though.  Most of them are only known as fossils today, but there is one living species of this group.  The sarcopterygians, or lobe-finned fish were the first known group to show this particular limb pattern.  The coelacanth also possesses the pattern.\n\nStrangely enough, the earliest known fossils of amphibians look amazingly similar to sarcopterygian fish with larger limbs.\n\nThis conservation of characters amongst all living terrestrial vertebrates is pretty powerful evidence for evolution having taken place, and that all of these diverse organisms developed through common descent from a single ancestor that first evolved this character.

The skeleton has two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, the spine, the ribs and the sternum (breastbone) and includes 80 bones. The appendicular skeleton, consisting of 126 bones,  includes two limb girdles (the shoulders and pelvis) and their attached limb bones.  \n\nBTW -why not learn to use google like everyone else!

Skeletal systems are commonly divided into three types - external (an exoskeleton), internal (an endoskeleton), and fluid based (a hydrostatic skeleton), although hydrostatic skeletal systems may be classified separately from the other two, since they lack hardened support structures\n\nhttp://en.wikipedia.org/wiki/Skeletal_system

Evolution of the aortic arch system has been one of progressive deletion and substitution, accompanied by a reorientation or rerouting of the blood supply.\nThe greatest changes in the system occurred in the transition from the holoaquatic to the terrestrial habit, with deletion of the first, second, and finally the fifth pairs of arches. Associated with these deletions, and the development of the pulmonary circulation, was reduction and atrophy of the dorsal portion of the\nsixth arches. Subsequently, evolution of the system has resulted in atrophy of one of the radices aortae (left in birds and right in mammals), loss of the left systemic arch in birds, and loss or functional modification of the right systemic arch in mammals.\nStill further changes and deletions in this system are found to occur in the birds.\nOf very common occurrence is reduction or loss of the dorsal portion of either the left or right 3rd aortic arch, accompanied by fusion of the dorsal carotids, anterior to the carotid arch (unicarotid condition). In a few instances, however, both left and right dorsal carotids become reduced to ligamentous vestiges (ligamentiottleyi) and cephalic blood flow is carried by the vertebral and superficialcervical arteries. In such instances, the dorsal portions of both left and right carotid arches become obliterated.\nWith loss of the left systemic arch, the left ductus caroticus loses its posterior connection, and usually becomes functionally modified. In most instances this is followed by a similar disconnection of the right ductus caroticus. The latter, however, frequently retains its connection between the carotid and systemic arches and remains as a patent vessel.\nRecent studies on 810 species and subspecies of birds have revealed the following, rather interesting, fact. In a single specimen of Megapodius freycinet layardi,\nand over 30 specimens of the Trochilidae, both left and right systemic (4th aortic) arches were lacking. In each of these instances, it was apparent that the right ductus caroticus remained as the functional systemic arch which carried the blood\nsupply to the abdominal aorta. Such a condition is not to be regarded as totally unexpected in the course of evolution of the aortic arch system, although it has not, to the writer's knowledge, been reported previously.\nThe particular significance of the occurrence of this reduction in Megapodius and among the Trochilidae cannot be satisfactorily evaluated at this time. It seems to me to be significant that the Trochilidae appear to present a highly uniform occurrence\nin the deletion of the right systemic arch, particularly in view of their rather restricted distribution. Evolution of this family of birds probably centered in\nSouth America, after an earlier origin from the common Apode stock in Antarctica.\nInsular isolation of Megapodius layardi may have been a factor contributing to the evolution and deletion of the right systemic arch in this specimen. It has not, however, been ascertained to what extent this deletion may occur in this species, but\nfurther studies might reveal the expected frequency of occurrence.\nIn conclusion, it may be expected that, in the course of evolution of the aortic arch system of birds, only the proximal or ventral portions of the 3rd aortic (carotid) ancl 6th aortic (pulmonary) arches and the right ductus caroticus will remain as the\nfunctional portions of the embryonic aortic arch system. The major cephalic blood supply will then be carried by the vertebral and superficial cervical arteries, while the blood supply to the abdominal region will be carried by the ductus\ncaroticus and abdominal aorta.

The Sarcopterygii, in particular the Rhipidistian Osteolepiformes such as Panderichthys\n\nPanderichthys had a number of morphological traits which place it in the lineage which gave rise to the tetrapods:\n\n- fin bones which fit the pattern of humerus, ulna and radius (forelimb) and femur, tibia, fibula (hindlimb) seen in all tetrapods\n\n- brain case so similar to early amphibians (Icthyostegans) that it was originally classified as one\n\n- lungs and choanate nostrils, but still possessed gills as well\n\n- teeth with infolding enamel identical to the earliest tetrapods\n\n- a spiracle (which becomes modified in later tetrapods into the stirrup bone of the inner ear)
