Anatomy of a Frog and Similarities to the Human Body

Amphibians have very simple skeletons and have less bones than other vertebrates, The skeleton and anatomy of a frog is similar to the human body. Frogs and Humans have the same kinds of organs and systems of organs. The frog's anatomy, however, is much simpler.

Man's internal organs are protected in the chest, the abdomen, and the pelvis. The human chest is separated from the abdomen by a powerful muscular partition, the diaphragm .There is no such partition in the frog's coelom. All the frog's internal organs including the heart, the lungs, and all organs of digestion are held in this single hollow space.

The frog's body is supported and protected by a bony framework called the skeleton 

The skull is flat, except for an expanded area that encases the small brain. Only nine vertebrae make up the frog's backbone, or vertebral column. The human backbone has 24 vertebrae. The frog has no ribs.

The shoulders and front legs of the frog are somewhat similar to man's shoulders and arms. The frog has one "forearm" bone, the radio-ulna. Man has two forearm bones, the radius and the ulna. Both frog and man have one "upper arm" bone, the humerus.

The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom.
