Anatomy and Function 1 of the Lumbar Spine 1.1 Anaomt y • The vertebral column consists of 24 vertebrae (7 cervical, 12 thoracic, and 5 lumbar) separated by intervertebral discs as well as 5 fused vertebrae forming the sacrum and a further 4 fused vertebrae forming the coccyx (Fig. 1.1).
1 sty 2001 · This report will explains some important normal anatomic features of the lumbar spine and sacrum including with their musclatures and neurovascular structures.
lumbar spine.1 The unique feature of the thoracic spine is the co-ordinated movement of the ribcage with the vertebral segments. The addition of the ribcage increases the re-quired compressive load necessary to cause buckling of the spine. 4 There is considerable motion of the spine and sternum independent of one another, allowing for
The lumbar spine is composed of five lumbar ver-tebrae (see Figs. 2-3 and 2-5, and Table 2-2). They are comparatively large for bearing the weight of the trunk and are fairly mobile, but not nearly as mobile as the cervical spine. The sacrum is composed of five fused vertebrae that form a single wedge-shaped bone (see Fig. 2-5 and Table 2-2).
14 sie 2023 · There are three main functions of the lumbar spine. First, the lumbar spine assists in supporting the upper body. The lumbar vertebrae (L1-L5) are much larger compared to other regions of the vertebral column, allowing them to absorb axial forces delivered from the head, neck, and trunk.
