Identify A, B and C, so as to complete the given statements Which is not the function of endoskeleton? Read the following statements about human skeleton system and choose the option that correctly states them true (T) and false (F).
a. Total number of bones in hind limbs are 60
b. There are 26 bones in vertebral column of an adult man
c. There are 2 pairs of vertebrochondral ribs

with rise in strength of stimulus.
Reason : This is due to increased contraction of
individual muscle fibres with increase in stimulus
strength.
