问题 解答题

如图是人体的关节模式图,请据图回答下列问题:

(请在括号内填字母,横线上填名称)

(1)脱臼是指(______)______从(______)______中脱落出来的现象.

(2)人体的运动系统是由______和______组成的.

答案

(1)脱臼:关节头从关节窝滑脱出来,是由于进行体育运动或从事体力劳动,因用力过猛或不慎摔倒所致.

(2)人体的运动系统由骨骼和肌肉组成.骨骼是由多块骨连接而成.

骨和骨之间的连接叫骨连接.有的骨连接是不能活动的,如脑颅骨各骨之间的连接;有的能半活动,如椎骨前方椎体间的连接;还有一种是能活动的,即一般所说的关节,如上肢的肩关节、肘关节,下肢的髋关节、膝关节等.关节是骨连接的主要形式.骨骼肌两端较细呈乳白色的部分是肌腱(属?于结缔组织),分别附着在相邻的两块骨上,中间较粗的部分是肌腹,主要由肌肉组织构成,外面包有结缔组织膜,里面有许多血管和神经,能够收缩和舒张.

故答案为:(1)(a);关节头;(d);关节窝;(2)骨骼;肌肉.
