Comparison of Vertebrate Limbs

Limbs of various vertebrates are provided: e.g. fish- Tilapia, amphibian-frog reptiles, lizard; bird – domestic fowl (chicken), mammal- rabbit.
Their anatomy can be studied.
The following can be noted:
That all limbs have five sets of bones;
A single upper bone- the femur in hind limb and the humerus in fore limb
Two lower limb bones -i.e. the tibia & fibula in the hind limb & ulna & radius in the forelimb.
Small bones – i.e. ankle (tarsals) and wrist bones (carpals)
