What are ten differences between a human skeleton and a frog skeleton?

Answer 1

1. The frog's pelvic girdle is tilted laterally to accomodate rearward extension of the legs.

2. The frog's phalanges are significantly longer relative to the metacarpal and metatarsal bones.

3. The frog's vertebral column lacks the cervical and lumbar curvatures.

4. The frog's skull has a foramen magnum shifted further back.

5. The frog's distal limbs do not have opposable thumbs.

6. The frog's pectoral girdle is much sturdier.

7. The frog's teeth are sharp and pointed.

8. The frog's carpals are rotated inwards.

9. The frog's eye orbit is significantly larger.

10. The frog's tibia and fibula are fused.

Answer 2

1. Humans have 206 bones in their skeleton, while frogs have around 250-260 bones.
2. Human skulls have a lower jaw that is fused to the cranium, while the frog's lower jaw is separate.
3. Frogs have a unique bone called the urostyle that forms part of their pelvic girdle, which humans do not have.
4. Human skeletons have a well-developed clavicle bone (collarbone), while frogs lack this bone.
5. Frogs have long digits and webbed feet, specialized for jumping and swimming, which are not present in human skeletons.
