The lumbar enlargement (or lumbosacral enlargement) gives attachment to the nerves which supply the lower limbs. It commences about the level of T11 and reaches its maximum circumference of about 33 mm. at L1 (lumbar vertebra) below which it tapers rapidly into the conus medullaris.An analogous region for the upper limbs exists at the cervical enlargement.
