It commences about the level of T11 and ends at L2, 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.

gollark: Why not just remove the channels per modem limit‽!?!?/⸘?!?!?
gollark: GTech operates a number of trilaterators, but they can only listen on known-in-advance channels because of the 128 channel limitation.
gollark: Of course, I think we really need 12 sniffers, 4 per dimension, so we can get good trilateration fixes.
gollark: * make 512 modems listen on 128 channels each
gollark: It's just a regular rednet one, not modem, right?
