What is the skeleton of a frog?
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.
What are the body parts of a frog?
Organs. Frogs possess a liver, heart, lungs, stomach, gall bladder and intestines. These organs perform the same functions for the frog as they do in human bodies: The heart pumps blood throughout the body, and the lungs aid in breathing.
How many regions are in a frog’s skeleton?

What are the parts of the dorsal side of the frog?

Does a frog has a backbone?
Amphibians are cold-blooded animals like reptiles and insects. Amphibians often vocalize, for example the ‘chorus’ of frogs. Amphibians are vertebrates, meaning they have a backbone. Reptiles, mammals, and birds have backbones, but they don’t share other amphibian characteristics.
