Anatomical terminology

The lumbar enlargement (or lumbosacral enlargement) is a widened area of the spinal cord that gives attachment to the nerves which supply the lower limbs.

It commences about the level of L1 and ends at S2, and reaches its maximum circumference, of about 33 mm. Inferior to the lumbar enlargement is the conus medullaris.[1]

An analogous region for the upper limbs exists at the cervical enlargement.
