腰脊是脊柱的组成部分之一。脊柱是由7块颈椎、12块胸椎、5块腰椎、5块骶椎和5块尾椎组成,它像一条锁链,一节一节地连接在一起,除5块骶椎和5块尾椎凝在一起不能活动外,其余7块颈椎、12块胸椎、5块腰椎都能活动。由于颈椎、胸椎、腰椎的形态结构不同,各自的活动范围也不同,颈椎活动范围大,腰椎次之,胸椎活动范围小。脊柱的运动靠各椎骨之间的活动,虽说椎骨与椎骨之间活动范围很小,但从整个脊柱而言,它的活动范围
The lumbar spine is one of the components of the spine. The spine is composed of seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae, five sacral vertebrae and five caudal vertebrae. It is like a chain, connected together in sections, with the exception of five sacral vertebrae and five caudal vertebrae Condensation can not be active, the remaining seven cervical spine, 12 thoracic vertebrae, 5 lumbar spine can move. As the cervical spine, thoracic spine, lumbar morphological structure is different, their range of activities are also different, cervical range of activities, followed by the lumbar spine, thoracic range of motion. The movement of the spine depends on the activity between the vertebrae. Although the range of motion between the vertebra and vertebra is very small, the range of motion of the spine
