The lumbar enlargement (or lumbosacral enlargement) gives attachment to the nerves which supply the lower limbs.

It commences about the level of the ninth thoracic vertebra, and reaches its maximum circumference, of about 33 mm., opposite the last thoracic vertebra, below which it tapers rapidly into the conus medullaris.
