Assertion: The phase of muscle contraction occurs when myosin binds and releases actin.
Reason: Muscle contraction is initiated by a signal sent by the peripheral nervous system via motor neuron.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
(c) If Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(c) If Assertion is correct but Reason is incorrect.
Explanation:
The phase of muscle contraction occurs when myosin binds and releases actin. Muscle contraction is initiated by a signal sent by the central nervous system via a motor neuron. A motor neuron along with the muscle fibres connected to it constitutes a motor unit.
