Anatomy Lower Limb Sem. 1 - Quiz

The lower limp is made up of 30 bones. The lower leg is the part of the lower limb that lies between the knee and the ankle. In semester one of the anatomy class we were able to cover much about the lower limb, its bones and how it meets its function. Take up the test below and refresh your memory.
