Your lumbar spine is the lower back region of your spinal column or backbone. It consists of five bones (L1-L5). Other structures in or around your lumbar spine are your intervertebral disks, spinal cord and nerves, muscles, tendons and ligaments.
Lower Back and Superficial Muscles. The muscles of the lower back help stabilize, rotate, flex, and extend the spinal column, which is a bony tower of 24 vertebrae that gives the body...
Understanding the anatomy of your lower spine can help you communicate more effectively with the medical professionals who treat your lower back pain. Here is a description of useful anatomical landmarks.
The thoracic spine: The thoracic spine is the middle part of the spine, connecting the cervical and lumbar spine. It has 12 vertebrae. The thoracic spine helps keep the body upright and...
The lower back comprises the lumbar spine, which is formed by vertebral bones, intervertebral discs, nerves, muscles, ligaments, and blood vessels. The spinal cord ends at the top of the lumbar spine, and the remaining nerve roots, called the cauda equina, descend down the remainder of the spinal canal.
The lower back (where most back pain occurs) includes the five vertebrae in the lumbar region and supports much of the weight of the upper body. The spaces between the vertebrae are maintained by intervertebral discs that act like shock absorbers throughout the spinal column to cushion the bones as the body moves.
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 vertebral column.
The lumbar vertebrae consist of five individual cylindrical bones that form the spine in the lower back. These vertebrae carry all of the upper body's weight while providing flexibility and movement to the trunk region.
It comprises the vertebral column (spine) and two compartments of back muscles; extrinsic and intrinsic. The back functions are many, such as to house and protect the spinal cord, hold the body and head upright, and adjust the movements of the upper and lower limbs.
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.
Learn how the lumbar spinal discs function and how lower back conditions can cause back pain and/or radiating pain.
WebMD's low back pain slideshow explains the most common causes of low back pain and what you can do to help alleviate it.
Lumbar Spine (Lower Back) Anatomy and Function. The anatomy of the lumbar spine is quite complex. Here we will attempt to provide a brief overview of lumbar spinal anatomy. The lumbar spine makes up the the lower end of the spinal column.
The back performs several important functions including housing and protecting the spinal cord, holding the body and head upright, bearing the weight of the upper body, transmitting this weight to the pelvic girdle and lower limbs when standing or walking, and facilitating the movements of the upper and lower limbs. Regions of the back.
Your spine is the long column of bones that extend from your neck to your lower back. Your spine starts at the base of your skull (head bone) and ends at your tailbone, a part of your pelvis (the large bony structure between your abdomen and legs). What does the spine look like? A healthy spine has three natural curves that make an S-shape.
The vertebral column of the lower back includes the five lumbar vertebrae, the sacrum, and the coccyx. These bones work together to provide flexibility to the trunk, support the muscles of the trunk, and protect the spinal cord and spinal nerves of the back.
The low back, also called the lumbar spine curves slightly inward. An inward curve of the spine is called lordosis. The lumbar spine is made up of the lower five vertebrae. Doctors often refer to these vertebrae as L1 to L5.
The lumbar spine (lower back) The lumbar spine carries the weight of the upper body. The lower back has a lot more motion than the thoracic spine and carries the weight of the torso, which makes it more prone to injury. The motion in the lumbar spine is divided between five motion segments.
Lower back region of the spine, consisting of five vertebrae, supporting the body's weight and allowing movement.
Lateral lumbar interbody fusion (LLIF) is a minimally invasive surgery that helps treat low back pain by removing a damaged spinal disc and fusing the pain-generating spinal segment (the two vertebrae above and below the disc space). Extreme lateral interbody fusion (XLIF) is a proprietary system for performing a particular type of LLIF and is ...
The flexor muscles are attached to the front of the spine and enable bending forward, lifting, and arching the lower back. The oblique muscles are attached to the sides of the spine and help rotate the spine and maintain proper posture. Watch Video: Understanding Different Types of Back Pain.
