As anyone who has dissected one in biology class knows, a frog's internal organs look a lot like what you'd find inside a much larger animal. Just like mammals -- including people -- a frog's body has a heart and lungs as well as a stomach, pancreas, liver, gallbladder and intestines.
Even though frogs don't look much like people on the outside, their skeletons are similar to people's skeletons, especially when it comes to their limbs. Just like in a person's arms, in a frog's front legs are bones called the humerus, the radius and the ulna. However, a frog's radius and ulna are fused into one bone. The same is true for a frog's legs -- the femur supports its upper leg, and the bones of the lower leg, the tibia and fibula, are fused. A frog has two scapulae, or shoulder blades, and clavicles, or collarbones, that are shaped a lot like the same bones in a person's body.
But a frog's skeleton isn't so similar to a human's once you get past the extremities. Frogs have skulls but don't have necks, so they can't turn, lift or lower their heads like people can. A frog also doesn't have ribs. The rib-like structures you can see in the picture above are part of its spine. A frog's pelvis can slide up and down its spine, which may help it jump. The vertebrae at the bottom end of the spine are fused into one bone called the urostyle.
