Between L3/ L4 or L5/L6
l2-3
The "L" in L5 stands for lumbar, indicating that the vertebra is part of the lumbar region of the spine, specifically the fifth lumbar vertebra.
An exaggerated lumbar curvature is known as hyperlordosis. It can result in excessive arching of the lower back, causing symptoms such as lower back pain, muscle tightness, and postural issues. It is important to address the underlying causes of hyperlordosis, which may include muscle imbalances, poor posture, or excessive body weight.
Symptoms of lumbar disc displacement can include lower back pain, pain that radiates down the leg (sciatica), numbness or tingling in the leg, weakness in the leg muscles, and difficulty with movement or flexibility in the lower back. It's important to seek medical evaluation for an accurate diagnosis and appropriate treatment.
The position of the spine is opposite of a curved or hunched position. It is meant to be straight, with the natural curves of the neck (cervical), upper back (thoracic), and lower back (lumbar) supported.
To prevent discomfort or injury while using a moving chair, ensure that it is adjusted to the correct height and position for your body. Take regular breaks to stand up and stretch, and use proper posture while sitting. Consider using a chair with lumbar support and adjustable armrests for added comfort and support.
I think you mean level of the vertebral column is a lumbar puncture generally performed?
spinal cord
Lumbar vertebral column
lumbar
because during the growth of human beings the vertebral column outgrows the spinal chord. that's why we don't find the spinal cord starting from lower lumbar region where lumbar puncture is done.
cervical, thoracic, lumbar, sacral and coccydial
Cervical Thoracic Lumbar Sacral
Erector spinae are the muscles that move the vertebral column.It is the largest muscle mass of the back, forming a prominent bulge on either side of the vertebral column.It is the chief extensor of the vertebral column. It is also important in controlling flexion, lateral flexion and rotation of the vertebral column and in maintaining the lumbar curve, because the main mass of the muslce is in the lumbar region.Consists of: iliocostalis, longissimus and spinalis.Erector spinae are the muscles that move the vertebral column.
A lumbar puncture is usually done between the third and fourth lumbar vertebrae (L3 and L4) as, in adults, the thick part of the spinal cord has ended by this point, meaning it can't be damaged by the lumbar puncture. The nerve fibres in this area are called the cauda equina (horse's tail) and they actually seem to move out of the way as the needle passes though into the cerebrospinal fluid.
thoracic curvature and lumbar curvature
cervical, thoracic, lumbar, sacral and coccydial
Lordosis an anteriorly convex curvature of the vertebral column; the normal lordoses of the cervical and lumbar regions are secondary curvatures of the vertebral column, acquired postnatally
