问题 填空题

同学们在进行对抗运动时,如打篮球,容易造成骨折,如果有同学骨折,尽量保持原状,防止造成二次伤害,且立刻送医院进行救治.______.

答案

从防止伤口感染、避免胫骨畸形和使断骨尽快愈合这些方面分析:①普通的毛巾包扎伤口,会使得毛巾上的细菌进入伤口,从而使伤口化脓.为了使得伤口不至于化脓感染,应用消过毒的毛巾包扎伤口.②骨骼肌包括肌腱和肌腹,骨骼肌两端是白色的肌腱,中间较粗的部分是肌腹.骨骼肌一般要跨越一个或是几个关节,由肌腱附着在相邻的骨上.骨折以后,为了使骨固定,不至于错位,应将较长的夹板把骨折两端的关节固定起来.③为了固定夹板,需要用绷带把夹板缠住,缠的时候注意松紧适度,既不能太松,使得夹板滑脱;也不能太紧,使得血液循环不通畅.所以以上做法都不太合理,应尽量保持原状,防止造成二次伤害,且立刻送医院进行救治,是为了保护骨膜,骨膜是骨表面除关节外所被覆的坚固的结缔组织包膜.在骨端和肌腱附着部位,非常致密地附着在骨上.其它部位的骨膜厚,容易从骨上剥离.骨膜由两部分构成,外层由胶原纤维紧密结合而成,富有血管、神经,有营养和感觉作用.内层也称形成层,胶原纤维较粗,并含有细胞.生长中的骨膜,在其内面有成骨细胞整齐排列,具有造骨细胞的功能,参与骨的增粗生长,对骨的生长(长长,长粗)和增生(断裂愈合)有重要作用.

故答案为:√.
