Lumbar Vertebra Anatomy

12 thoracic vertebrae of the chest. The lumbar spine consists of 5 moveable vertebrae numbered l1 l5.

Lumbar vertebra anatomy. Introduction to lumbar vertebrae anatomy. The lumbar vertebrae consist of five individual cylindrical bones that form the spine in the lower back. These vertebrae are characterized by the absence of the foramen transversarium within the transverse process and by the absence of facets on the.

These vertebrae carry all of the upper bodys weight while providing flexibility and movement to the trunk region. A weakened disc may rupture or bulge putting pressure on the spinal nerve roots. This triangle shaped bone is made up of five fused vertebrae.

The lumbar spines lowest two spinal segments l4 l5 and l5 s1. Numbered l1 through l5 these odd shaped vertebrae signal the end of the typical bones of the spinal column. Lumbar spine lower back anatomy and function 7 cervical vertebrae which make up the neck.

The lumbar spine meets the sacrum at the lumbosacral joint l5 s1. They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process and by the absence of facets on the sides of the body. Lumbar spine anatomy helps you understand low back pain.

Since these vertebrae are most largely responsible for bearing the weight of the upper body and permitting movement they are logically also the largest segments of the vertebral column. The lumbar spine has several distinguishing characteristics. The lumbar vertebrae vertebrae lumbales l1 l5 are located in the lower back and are discernibly larger and stronger than the cervical or thoracic vertebrae.

They are designated l1 to l5 starting at the top. The complex anatomy of the lumbar spine is a remarkable combination of these strong vertebrae multiple bony elements linked by joint capsules and flexible ligamentstendons large muscles and highly sensitive nerves. The spines vertebrae are cushioned by gel like discs that are prone to wear and tear from aging or injuries.

Now that you have learned about lumbar spine anatomy perhaps you can better understand whats causing your low back pain. The lumbar vertebrae are in human anatomy the five vertebrae between the rib cage and the pelvis. It fits like a wedge into the back of the pelvis at the hips.

The lumbar vertebrae help support the weight of the body and permit movement. The lower the vertebra is in the spinal column the more weight it must bear. The lumbo sacral spine includes.

It also has a complicated innervation and vascular supply. The lumbar vertebrae are located at the bottom section of the vertebral column inferior to the rib cage and superior to the pelvis and sacrum. The lumbar spine is an intricate system and an injury to the vertebrae eg spinal fracure or to the discs eg herniated disc can cause pain.
