Is spondylolisthesis the forward movement of the body of one of the lower lumbar vertebra on the vertebra below it or on the sacrum?
Spondylolisthesis is the forward displacement of one vertebra over the one beneath it. It commonly occurs in the lower lumbar region, especially between the fifth lumbar vertebra and the first sacral vertebra (L5-S1).
What is the forward slipping movement of a lower lumbar vertebra's lower body on the vertebra or sacrum below it?
Forward slipping movement of a lower lumbar vertebra relative to the vertebra or sacrum below it is known as spondylolisthesis. This condition can be caused by degenerative changes, trauma, congenital defects, or repetitive stress on the spine. It can lead to symptoms such as back pain, sciatica, and neurological deficits. Treatment options depend on the severity of the slippage and may include physical therapy, bracing, or surgery.
Where in the body does the spinal cord end?
The spinal cord ends at the level of the first lumbar vertebra, which is just below the level of the ribs.
Is the L2 vertebrae located above or below the waist?
The L2 vertebra is located below the waist. It is part of the lumbar region of the spine, which consists of five vertebrae (L1 to L5) situated in the lower back. The lumbar region is typically considered to be below the rib cage and above the sacrum, aligning with the waist area.
How can you distinguish a lumbar vertebra from a cervical vertebra?
the nerve cord is enclosed while a invertabrae nerve is opened
Is Spondylolisthesis a subluxation of one vertebra over the one below it?
Yes, spondylolisthesis is a condition where one vertebra slips forward over the vertebra below it. It can cause back pain, leg pain, and muscle tightness. Treatment options may include physical therapy, bracing, or surgery in severe cases.
Where is the t-12 located in your back?
The T-12 vertebra is located in the lower part of the thoracic spine, just above the lumbar region. It is the last of the twelve thoracic vertebrae and is situated between the T-11 vertebra above and the L-1 vertebra below. The T-12 vertebra plays a crucial role in supporting the rib cage and facilitating movement in the back.

What is vacuum phenomenon with retrolisthesis of L5 on S1 of approximately 3MM?
The lowest lumbar vertebra has slid backwards by 3mm compared to the backbone below it, causing a change in the appearance of the disk between them.
Why is the arachnoid membrane the site for a lumbar puncture?
The arachnoid mata is not the site of a lumbar puncture. The site of a lumbar puncture is between the level of L4 and L5 vertebra in the lumbar section of the spine. This is used because at this point and below, there is no spinal cord to damage. The LP draws a liquid known as cerebrospinal fluid (CSF) from the meninges surrounding the spinal cord in order to examine for infection risk mainly.
What is lumber in the human body?
The lumbar spine is the lower back that begins below the last thoracic vertebra (T12) and ends at the top of the sacral spine, or sacrum (S1). Most people have 5 lumbar levels (L1-L5), although it is not unusual to have 6. Each lumbar spinal level is numbered from top to bottom—L1 through L5, or L6.13-
Can someone have 6 lumbar vertebrae?
Yes. This is due to a normal variant in the development of the spine called lumbarization. This occurs when the first segment of the sacral spine (which is just below L5 and normally referred to as S1) fails to fuse with the sacrum, resulting in what appears to be a 6th lumbar vertebra, an L6.The result of this 6th lumbar vertebra is merely an extra movable segment in the spine and is generally not considered an abnormality or anything that needs to be treated.
