Mechanism Of Muscle Contraction

Which of the statements about the mechanism of muscle contraction are correct? I. acetylcholine is released when the neural signal reaches the motor end plate II. muscle contraction is initiated by a signal sent by CNS via a sensory neurone III. during muscle contraction, isotropic band gets elongated. IV. repeated activation of the muscles can lead to lactic acid accumulation.

Which of the statements about the mechanism of muscle contraction are corrcet (I) Acetylcholine is released when the neural signal raches the motor end plate (II) Muscle contration is initiated by a singnal sent by CNS via a sensory neuron (III) During muscle contration, isotropic band gets elongated (IV) Repeated activation of the muscles can be lead to lactic acid eccumulation

Given an idea about mechanism of muscle contracting along with a suitable diagram.

Explain the mechanismof muscle contraction.
