What is the lumbar region?

What is the lumbar region?

The lumbar region of the spine, more commonly known as the lower back, consists of five vertebrae labeled L1 through L5. The lumbar region is situated between the thoracic, or chest, region of the spine, and the sacrum. These muscles can spasm or become strained, which is a common cause of lower back pain.

What are the characteristics of the lumbar?

Distinguishing features of the lumbar vertebrae include a thick and stout vertebral body, a blunt, quadrilateral spinous process for the attachment of strong lumbar muscles, and articular processes that are oriented differently than those found on the other vertebrae.

What are the characteristics of lumbar vertebrae?

Typical lumbar vertebrae have several features distinct from those typical of cervical or thoracic vertebrae. The most notable distinction is the presence of a large vertebral body. The spinous process is short and thick, relative to the size of the vertebra, and projects perpendicularly from the body.

What is the function of the lumbar region?

The range of motion in the thoracic spine is limited. Lumbar (low back) – the main function of the lumbar spine is to bear the weight of the body. The five lumbar vertebrae are numbered L1 to L5. These vertebrae are much larger in size to absorb the stress of lifting and carrying heavy objects.

Where is my lumbar?

The low back, also called the lumbar region, is the area of the back that starts below the ribcage.

What is a spinal lumbar?

The lumbar spine (lower back) consists of five vertebrae in the lower part of the spine, between the ribs and the pelvis. Lumbar spinal stenosis is a narrowing of the spinal canal, compressing the nerves traveling through the lower back into the legs.

How do you differentiate a lumbar vertebrae?

The main distinguishing feature of the lumbar vertebrae is the orientation of the facets on the superior and inferior articular processes. The facets on the superior articular processes face medially and posteriorly, and the facets on the inferior articular processes face laterally and anteriorly.

How does the lumbar vertebrae look like?

Body. The vertebral body of each lumbar vertebra is kidney shaped, wider from side to side than from front to back, and a little thicker in front than in back. It is flattened or slightly concave above and below, concave behind, and deeply constricted in front and at the sides.

What is the lumbar muscle?

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 structure and houses the spinal cord. The spinal cord and its nerves are the means by which the body and brain communicate with one another.

What is a lumbar spine?

How does the shape of the lumbar region occur?

The lumbar spine bends inward to create a C-shaped lordotic curve. Sacrum: This triangle-shaped bone connects to the hips. The five sacral vertebrae (S1 to S5) fuse as a baby develops in the womb, which means they don’t move. The sacrum and hip bones form a ring called the pelvic girdle.
