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 first lumbar spinal nerve (L1) [1] originates from the spinal column from below the lumbar vertebra 1 (L1). The three terminal branches of this nerve are the iliohypogastric, ilioinguinal, and the genitofemoral nerves. L1 supplies many muscles, either directly or through nerves originating from L1.
The lumbar cistern is part of the subarachnoid space.It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra.
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 lower border of first lumbar vertebra lies at the level of the transpyloric plane. [3] Despite the conus medullaris, the end of the spinal cord, being understood to typically terminate at the level of the transpyloric plane, there is significant variability. Up to 40% of people have spinal cords ending below the transpyloric plane. [2] [4]
It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, on the level of the first lumbar vertebra. The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and posterior vagal trunks.
The 2025 Club World Cup is a first-of-its-kind tournament that, in FIFA’s dreams, is precisely what its name suggests. It’s a 32-team extravaganza modeled after soccer’s actual World Cup, ...
The lateral arcuate ligament is commonly described in anatomy textbooks as attaching at the first lumbar vertebra (L1). [2] However, other instances have been found in cadaver studies with attachments at either the second (L2) or third (L3) lumbar vertebra.
