skelton and the frog's skelton system

Question

Robert · Accepted Answer

The morphology of frogs is unique among amphibians. Compared with the other 
two groups of amphibians, (salamanders and caecilians), frogs are unusual 
because they lack tails as adults and their legs are more suited to jumping than 
walking. The physiology of frogs is generally like that of other amphibians (and 
differs from other terrestrial vertebrates) because oxygen may pass through their 
highly permeable skin. 
 This unique feature allows frogs to "breathe" largely through their skin. Because 
the oxygen is dissolved in an aqueous film on the skin and passes from there to 
the blood, the skin must remain moist at all times; this makes frogs susceptible to 
many toxins in the environment, some of which can similarly dissolve in the layer 
of water and be passed into their bloodstream. This may be a cause of the decline 
in frog populations. 
 
What is skeletal system? 
 
consists of bone and cartilageserves as the framework of the body supports and 
protects organs 
provides attachment for the muscles.
The skeletal system performs many functions which include:  
1. Support the body.  
2. Protect vital organs such as the heart.  
3. Move the body.  
Divisions of the skeletal system.  
The frog skeletal system is divided into two regions the axial skeletal system and 
the appendicular system.  
 
The axial skeleton consists of the skull, vertebral column, and sternum.  
 
The appendicular system consists of the pectoral girdle, forelimbs,
