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
