articulations,关节的运动,movements of articulations,关节的分类,classification of articulations,一骨连接的分类 Classification of joints,人体骨和骨之间借结缔组织、软骨或骨相连形,成骨连结。,从骨连结的形式可分为直接连结（不动连接）和,间接连结（可动连接，关节）两种。,韧带连结,Syndesmosis,缝,suture,纤维软骨结合,Symphysis,骨性结合,Synosteosis,间接连结又称关节,articulation,或滑膜关节,synovial joint,是骨连结的最高分化形式，具有较大的活动性。,二关节的基本构造 Basic structures of articulations,关节面 Articular surface,关节软骨articular cartilage,关节囊 Articular capsule,纤维膜 Fibrous membrane,滑膜 Synovial membrane,关节腔 Articular

movements of articulations,角度运动：,1、屈flexion和伸extension,2、收adduction和展abdution,踝关节的屈又称跖屈，伸又称背伸。,旋转运动rotation：,内旋和外旋；旋前和旋后,环转运动circumduction：,移动translation,五 关节的分类 classification of articulations,单轴关节 Uniaxial joints:,屈戍关节 hinge joints,车轴关节 trochoid(pivot)joints,双轴关节 Biaxial joints:,椭圆关节 ellipsoid joints,鞍状关节 saddle joints,多轴关节 Multiaxial joints:,球窝关节 ball-and-socket joint,平面关节 plane joints,根据参与构成关节骨的数目将关节分为二类,：,单关节 如 掌指关节 复关节 如 肘关节,根据关节的运动形式也可将 关节分为二类：,单动关节 如 肩关节 联合关节 如 颞下颌关节,影响关节的灵活性 和稳固性因素,关节面的形态是决定关节运动轴和运动方式的结构基础，运动轴愈多，运动形式就愈多样化，愈灵活；其次，关节头和关节窝的面积差，也反映出运动的灵活与否，同类关节，两者的面积差愈大，运动幅度也愈大，反之面积差越少，则趋于稳固。再其次，关节囊的厚薄、松紧，周围韧带和肌腱的状况也明显影响着关节的运动。,思 考 题,解剖学姿势、常用术语,骨的形态分类、构造,骺软骨与人体长高有何关系？,骨的物理性质随年龄怎样变化，为什么？,你如何理解“没有解剖学就没有医学”这句话？,简答关节的基本构造，辅助构造及关节的运动。,躯干骨及其连结,Bones of trunk and their
