Lumbar Spine Anatomy Biology Diagrams The lumbar spine is located in the lower half of the vertebral column, inferior to the thoracic vertebrae/rib cage and superior to the pelvis and sacrum.. The lumbar vertebrae are five in number and desginated as vertebrae L1-L5.They are primarily responsible for bearing the weight of the upper body (and permitting movement) and consequently represent the largest individual segments of the
The lumbar spine also houses and protects the spinal cord's nerves as they exit towards the lower body. Location. The lumbar spine is located in the lower back, between the thoracic spine (mid-back) and the sacrum (pelvic region). It is the region just above the buttocks. [6] Structure and Anatomy
Lumbar Spine Anatomy and Function Biology Diagrams
Definition and anatomy of the lumbar spine. The lumbar spine is part of the spinal column. Located between the dorsal spine and the sacrum, it is made up of 5 bones, or vertebrae, numbered from L1 to L5. The vertebrae are separated from each other by intervertebral discs. These discs help absorb shock and also facilitate back movement.
Anatomy of the Lumbar Spine . In a normal, healthy spine, the five lumbar vertebrae stack on top of one another in a centered alignment. While all vertebrae have approximately the same shape, the lumbar bones are the largest. This is because they carry a larger load transmitted from the top of the head down to the lower spine. The lumbar spine is the third region of the vertebral column, located in the lower back between the thoracic and sacral vertebral segments.. It is made up of five distinct vertebrae, which are the largest of the vertebral column. This supports the lumbar spine in its main function as a weight bearing structure.
