Read the following statements and select accordingly.
Statement-A : Tetany can occur due to excess of thyrocalcitonin.
Statement-B : Muscle fibre contracts to the maximum when the stimulus has atleast the threshold value.
Statement-A : Tetany can occur due to excess of thyrocalcitonin.
Statement-B : Muscle fibre contracts to the maximum when the stimulus has atleast the threshold value.
View answer and explanation
Correct option: C
Both statements A and B are correct
Option C (Both statements A and B are correct) is correct because tetany can be caused by hypocalcemia due to excess thyrocalcitonin, and muscle fibers contract maximally at or above the threshold stimulus.

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

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