Examining a Frog's Anatomy

A detailed Summary of Examining a Frog's Anatomy

The frog is one of the best example of how its skeleton and muscles have adapted to provide the best response to the natures challenges. Indeed, we will notice in the paragraphs below that each muscle and each bone has a well-determined function in providing for an excellent jumper and swimmer. In general, the skeleton is correlated with the moving function. Because of the frog's specific environment and the aquatic component it is dealing with, the skeleton of a frog refers to both swimming and leaping as kinetic modalities. The skeleton is, as such, adapted to perform these tasks.

First of all, the tibia and fibula have joined to form the tibiofibula and it has specialized in providing an excellent leaping and jumping basis. Man has two lower leg bones, but it seems natural that for the frog, these two have joined together in order to provide for the best solution in the environment the frog lives. The muscles are also adapted to provide excellent jumping skills and to support the lower leg bones, the tibiofibula.

Further more, the tibiofibula provides the best adaptation for swimming and thus covers the two main activities in the frog's life. In terms of swimming, if we look at a drawing of the frog skeleton, the tibio

From our list of subjects, the mandible is perhaps the only one not adapted to movement, but rather to feeding. The mandible and the components of the mouth in a frog are closely connected. For example, as the mouth, closely linked to the mandible mechanism, opens, the tongue instantly springs out in order to pursue its prey4.

On the other hand, a frog's molded tibiofibula is a swimmer's mechanism. Besides providing enough strength for swimming, it also has the aerodynamic condition that permits a swift movement in the water. If the frog had two lower leg bones like the human, than it is likely that it may have moved slower through the water, because of the existing friction force.

This is obviously not the case here. Because the frog's body is much more important in its evolution in the environment, because the body is needed to perform complex movement action, such as leaping and swimming, it is quite clear that the most important and the most numerous vertebrae should be in the abdominal area. Proportional to the frog's body length and skull/head weight, there is only one boned required to perform the usual sustaining action.

On the other hand, much of a frog's time is spent in the pond, in water hence. Moving around fast in the aquatic environment is essential, because it means the frog can avoid possible natural predators, such as aquatic birds, and, additionally, it can pursue its own food sources in proper timing.

If we look at these two types of bones, the leg bones and the 'arm' bones, we may see that these have gradually adapted themselves to the requirements of the frog's outer environment. The frog relies greatly in its movement on land on jumping, short leaps that are able to carry it speedily in the area around the pond.

The rather large mandible, as compared to the rest of the body allows for a well-adapted mechanism to function correctly in the environment the frog lives in. Indeed, the close connection between mouth, mandible and tongue is adapted to catch the insects or flies that the frog eats in the pond ecosystem and environment.
