In infants the spinal cord
extends from the base of the medulla oblongata and terminates between vertibra
L4 and L5 of vertebral coloumn. The curved caudal terminal part of the spinal
cord is the conus medularis. The pia matter around the conus medularis connects
the conus medularis to the innerside of the coccygeal vertibra. In adults the
spinal cord ascends in the vertebral column and the conus medularis comes to
lie between L2 and L3 vertibra. The pia matter connecting the conus medularis
with the coccygeal vertibra now elongates forming the filum terminalis.
Cauda eqina is a collective
term given to anterior and posterior roots of the thoracic sacral and lumber
nerves.
