The superior lumbar (Grynfeltt-Lesshaft) triangle is formed medially by the quadratus lumborum, laterally by the posterior border of internal abdominal oblique muscle, and superiorly by the 12th rib. The floor of the superior lumbar triangle is the transversalis fascia and its roof is the external abdominal oblique muscle.
The alae also form the base of the lumbosacral triangle. The iliolumbar ligament and lumbosacral ligaments are attached to the ala. In the middle of the base is a large oval articular surface, the upper surface of the body of the first sacral vertebra, which is connected with the under surface of the body of the last lumbar vertebra by an ...
The lumbar region is sometimes referred to as the lower spine, or as an area of the back in its proximity.. In human anatomy the five lumbar vertebrae (vertebrae in the lumbar region of the back) are the largest and strongest in the movable part of the spinal column, and can be distinguished by the absence of a foramen in the transverse process, and by the absence of facets on the sides of the ...
The lumbar vertebrae are located between the thoracic vertebrae and pelvis. They form the lower part of the back in humans, and the tail end of the back in quadrupeds. In humans, there are five lumbar vertebrae. The term is used to describe the anatomy of humans and quadrupeds, such as horses, pigs, or cattle.
The dimples of Venus (also known as back dimples, butt dimples or Veneral dimples) are sagittally symmetrical indentations sometimes visible on the human lower back, just superior to the gluteal cleft. They are directly superficial to the two sacroiliac joints, the sites where the sacrum attaches to the ilium of the pelvis. An imaginary line ...

This happens for a variety of reasons- the lower waist area is a pivot point for the body and lengthens and arches as a person sits or bends.

The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a complex, [1]: 1137 multilayer arrangement of fascial and aponeurotic layers forming a separation between the paraspinal muscles on one side, and the muscles of the posterior abdominal wall (quadratus lumborum, and psoas major [1]: 1137 ) on the other.
