Question

Why are frog bone named after human bones?

Answer 1

he shoulders and front legs of the frog are somewhat similar to human's shoulders and arms. The frog has one "forearm" bone, the radio-ulna. Humans have two forearm bones, the radius and the ulna. Both frog and human have one "upper arm" bone, the humerus.Frogs have long, strong back legs, with extra joints so they can fold up close to the body. Tails would get in the way when jumping, so frogs do not have one. They have a short backbone (spine), with a large hip bone to support their powerful leg muscles. ... Only one species of frog has teeth in its lower and upper jaws.ven 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.

Answer 2

Answer:

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.

A collection of small bones makes up a frog's digits, or its fingers and toes. Most of the time, a frog has five toes on its back legs and four toes on its front legs. The length and shape of the toes has a big impact on how the frog moves. Tree frogs have long, flexible toes that allow them to grasp stems and branches as they climb around. Aquatic frogs also have long toes -- the spaces between them are webbed so they can use their feet like flippers. Some frogs burrow into the soil in the summer or winter. Often, their feet are shorter and wider, like shovels or spades.
