肋骨共有十二对,左、右各为12根。分为膈上肋骨(10对)和膈下肋骨(第十一和十M)。隔上10对肋骨自后方向前下方弯曲而行,包绕着胸内各器官。每根肋骨分为前肢、体部和后肢三部,前肢与肋软骨相连接。上方7对肋软骨向下方渐次增长,其末端连于胸骨。下方3对肋骨渐次变短,每根末端与其上方肋骨的下缘形成关节。肋软骨在照片上不显影,但随年龄的增长,渐次钙化而能显影。肋骨后肢端头部与脊椎形成肋推关节,结节与脊椎横突形成横突关节。 由于肋骨解剖上的特点:弯曲不直,大部分位于膈
A total of twelve pairs of ribs, left and right for the 12 root. Divided into diaphragmatic upper ribs (10 pairs) and subphrenic ribs (eleventh and ten M). Septal 10 pairs of ribs from the front to the bottom of the curved line, surrounded by various organs within the chest. Each rib is divided into three parts, the forelimb, body and hind limbs, forelimbs connected with costal cartilage. Above the seven pairs of costal cartilage gradually increased downward, the end connected to the sternum. The lower three pairs of ribs gradually become shorter, each end with the lower edge of the upper rib to form joints. Costal cartilage does not develop in the photo, but with age, gradual calcification and development. Ribs hind limbs and vertebrae forming rib push joint, nodules and spinal transverse process to form transverse processes. Due to the anatomical features of the ribs: the curvature is not straight, most of the diaphragm
