How do our muscles move class 10 bio Pls answer in detail |

Answer» The nerve fibres at the END of a neuron are attached to muscles. This area is CALLED neuro-muscular junction. When nerve IMPULSES are conducted to this area, the special proteins present in the muscle cells change their SHAPE and arrangement in the cell in RESPONSE to nervous electrical impulses. New arrangement of these proteins give the muscle cells a shorter form thus bringing about movement of muscles. |
