<em>Low calcium level in body may cause a condition called hypocalcemia.

<u>Explanation:</u>
When a <em>person has the condition of hypocalcemia his/her muscles and nerves that are releted to calcium levels in blood</em> will undergo spasms or twitching. This is generally termed as muscular irritability. <em>Muscle cramps in leg and arms are symptoms of hypocalcemia.
