观察右边关节结构图,思考回答下列问题:

⑴使关节牢固的结构有〔 〕       和其外的      

⑵使关节灵活的因素有关节面上的[    ]      和〔   〕      中由〔   〕         分泌的滑液

(3)脱臼指的是[   ]      从[    ]          里滑脱出来。

答案

⑴〔 4〕关节囊 韧带

⑵ [ 2   ]关节软骨 〔  5 〕 关节腔 〔  4 〕关节囊内壁

(3) [  1  ] 关节头  [  3  ]关节窝

题目分析:由图可知:1是指关节头,2是指关节软骨,3是指关节窝,4是指关节囊,5是指关节腔,关节是由关节面、4关节囊和5关节腔三部分组成,关节面包括1关节头和3关节窝,使关节牢固的结构特点是:关节囊及囊里面、外面的韧带,使关节运动灵活的结构特点是:关节面上覆盖一层表面光滑的2关节软骨,和关节囊的内表面还能分泌滑液,可减少运动时两骨间关节面的摩擦和缓冲运动时的震动,关节腔由关节囊和关节面共同围成的密闭腔隙,内有少量滑液,滑液有润滑关节软骨的作用,可以减少骨与骨之间的摩擦,使关节的运动灵活自如,脱臼指的是关节头从关节窝滑脱出来的现象。

点评:此题为基础知识题,解答此题的关键是掌握关节的结构,可结合关节的结构图进行掌握。
