2 骨借关节相连形成骨骼,骨骼支持体重,保护内脏。 骨骼肌附着于骨,在神经系统支配下收缩舒张,以关节为支点牵引骨改变位置,产生运动。
运动系统由骨、关节、骨骼肌构成。 骨借关节相连形成骨骼,骨骼支持体重,保护内脏。 骨骼肌附着于骨,在神经系统支配下收缩舒张,以关节为支点牵引骨改变位置,产生运动。 January, 2007 Copyright© Depart. Anatomy, School of Medicine, Lanzhou University. All right reserved by YP HOU and YF SONG

4 总 论 骨(bone)是人体重要的器官之一,骨组织主要由骨细胞、胶原纤维和基质等构成。外被骨膜,内容骨髓,含有丰富的血管、淋巴管及神经;是人体钙、磷的储存库,参与体内钙、磷代谢。骨髓有造血功能。 January, 2007 Copyright© Depart. Anatomy, School of Medicine, Lanzhou University. All right reserved by YP HOU and YF SONG

5 总 论 一.骨的分类 二、骨的表面形态 三、骨的构造 四、骨的化学成分和物理性质 五、骨的发生和发育 六、骨的可塑性

11 骨的化学成分和物理性质 骨主要由有机质和无机质组成。 两种成分的比例,随年龄的增长而发生变化:
幼儿时期骨的有机质和无机质各占一半,故弹性较大,柔软,易发生变形。 成年人骨有机质和无机质的比例约为3:7,最为合适,因而骨具有很大硬度和一定的弹性,较坚韧。 老年人的骨无机质所占比例更大,骨的脆性较大,易发生骨折。 January, 2007 Copyright© Depart. Anatomy, School of Medicine, Lanzhou University. All right reserved by YP HOU and YF SONG

12 骨的发生和发育 骨的发生 骨的发育 January 07

13 骨的可塑性 骨的基本形态是由遗传因子调控的。 影响骨生长发育的因素:神经、内分泌、营养、疾病及其它物理化学因素、环境因素等。
骨折后,折断处有骨痂形成。骨折愈合的初期,骨痂颇不规则,经过一定时间的吸收和改建,骨可基本恢复原貌。 January 07 Copyright© Depart. Anatomy, School of Medicine, Lanzhou University. All rights reserved by Prof.YP Hou and YF Song
