The second lumbar spinal nerve (L2) [2] originates from the spinal column from below the lumbar vertebra 2 (L2). L2 supplies many muscles, either directly or through nerves originating from L2. They may be innervated with L2 as single origin, or be innervated partly by L2 and partly by other spinal nerves. The muscles are: quadratus lumborum ...
In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
L1 – Midway between the key sensory points for T12 and L2. [clarification needed] L2 – On the anterior medial thigh, at the midpoint of a line connecting the midpoint of the inguinal ligament and the medial epicondyle of the femur. L3 – At the medial epicondyle of the femur. L4 – Over the medial malleolus.
The genitofemoral nerve is a mixed branch of the lumbar plexus derived from anterior rami of L1-L2.It splits a genital branch and a femoral branch.It provides sensory innervation to the upper anterior thigh, as well as the skin of the anterior scrotum in males and mons pubis in females.
It occurs near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower. [1] [2] The upper end of the conus medullaris is usually not well defined, however, its corresponding spinal cord segments are usually S1–S5. After the spinal cord tapers out, the spinal nerves continue to branch out diagonally, forming the cauda equina. [1]
The top four seeds, as expected, were No. 1 Oregon, No. 2 Georgia, No. 3 Boise State and No. 4 Arizona State. Those teams will host the winning teams from the opening round in the quarterfinals.

The journal was established in 1867 as the Journal of Anatomy and Physiology. [4] The journal was conceived at the 1866 meeting of the British Association in Nottingham by founding editors George Murray Humphry (University of Cambridge), William Turner (University of Edinburgh), Alfred Newton (University of Cambridge), and Edward Perceval Wright (Trinity College Dublin).
