Vedclass · Answer

(C) The assertion is correct because muscle contraction involves the formation and breaking of cross-bridges between myosin heads and actin filaments,known as the sliding filament theory.The reason is incorrect because muscle contraction is initiated by a signal sent by the $Central \ Nervous \ System$ $(CNS)$,not the peripheral nervous system,via a motor neuron.Therefore,the assertion is correct,but the reason is incorrect.

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.
