Free and printable frog diagrams have been collected for you to print in high definition and quality. Dissection is a part of biology lesson, and sometimes frog is one object of dissection. Frogs are amphibians, living both on land and in water. Their anatomy is very unique. Their bodies are similar to humans in that they have skin, bones, muscles, and organs. The body of a frog can be divided into a head, a short neck, and a trunk. Take a look at the following diagrams to see the details.
As you can see in the frog diagram above, the body structure, or anatomy, of the frog is very similar to the anatomy of man. Both man and the frog have the same kinds of organs and systems of organs. The frog’s anatomy, however, is much simpler. The head of a frog contains the brain, mouth, eyes, ears and nose. The frog’s head movement is limited due to the short, almost rigid neck. The trunk of a frog forms walls for a single body cavity known as the coelom. The coelom holds all of the frog’s internal organs.
Frogs have a long, sticky tongue which they use to capture food. They also have teeth, which unfortunately are very weak and rather useless. The internal structures of a frog include: the heart, the lungs, the kidneys, the stomach, the liver, the small intestine, the large intestine, the spleen, the pancreas, the gall bladder, the urinary bladder, the cloaca, the ureter, the oviducts, the testes, the ovaries and fat bodies. These images of the frog oral cavity and internal anatomy are designed to help you identify various structures of frog.
The frog does not have a tail. Only a spikelike bone, the urostyle, remains as evidence that primitive frogs probably had tails. The urostyle, or “tail pillar,” is a downward extension of the vertebral column. The last diagram above is the unlabeled version that can be used as the evaluation or quiz media.
