GROSS ANATOMY

Detailed explanation-1: -Lordosis develops if your spine curves too much and pushes your posture out of its usual alignment. You might see lordosis that affects your lumbar spine called swayback. Remember, lordosis is normal in the cervical and lumbar spine. In the cervical spine, a 30-to 40-degree curve is normal.

Detailed explanation-2: -Swayback; Arched back; Lordosis-lumbar. Lordosis is the inward curve of the lumbar spine (just above the buttocks). A small degree of lordosis is normal. Too much curving is called swayback.

Detailed explanation-3: -Kyphosis. Kyphosis is an abnormal forward rounding (more than 50 degrees of curvature) of the spine. In the upper (thoracic) back, kyphosis is commonly due to osteoporotic compression fractures. It can also occur in the lower (lumbar) spine.

Detailed explanation-4: -What Is Lordosis? Lordosis is the natural curve of the lower back (lumbar) area of the spine. With an extreme curve, the lower spine will have a deep curve, causing the abdomen (stomach area) to stick out and causing the pelvis (hip areas) to curve back and up.

Detailed explanation-5: -Poor posture is one of the most common causes of hyperlordosis. When the body is in a seated position, muscles in the lumbar region can tighten too much as they try to stabilize and support the spinal column. This gradually pulls the spine out of alignment, causing increased curving of the spine.
