问题 读图填空题

(8分)人和脊椎动物的运动系统由骨、              三部分组成;运动是以        为杠杆,         为支点,骨骼肌收缩为         形成的。骨骼肌的收缩要受             的协调和控制;而运动需要消耗     ,这来自于     内有机物的氧化分解。 

答案

此题主要考查了骨、关节、骨骼肌的协调配合与运动的产生,骨的位置变化产生运动,但是骨本身是不能产生运动的,骨的运动要靠骨骼肌的牵拉,骨骼肌有受刺激而收缩的特性,当骨骼肌受神经传来的刺激收缩时,就会牵动骨绕关节活动,于是躯体就会产生运动,运动不仅靠运动系统来完成的,它需要神经系统的调节和控制,能量来源于肌细胞的呼吸作用分解有机物释放。
