Identify the correct statements I. Acetylcholine is released when the neural signal reaches to the motor end plate II. Muscle contraction is initiated by signals sent by CNS a sensory neuron III. During muscle contraction, isotropic bands get elongated IV. Repeated activation of the muscles can lead to lactic acid accumulation in them The option with correct choices is |

(b)
The junction between a motor neuron and sarcolemma of muscle is called neuromuscular junction
(i) A neural signal reaching this junction (motor end plate) release a neurotransmitter
(ii) Repeated activation of muscles can lead to the accumulation of lactic acid due to anaerobic break down of glucose in them
