Discussion The “Caudal” Spinal “Cord”
My writings in the neuroanatomy of the mind/body interface have led me to contemplate an interesting the homophonic and potential cognate pairing of cord as in ‘spinal cord’ and caudal (‘tail-end’ as counter polar to cephalic (‘at the head end’). ‘Cord’ appears to come from the PIE ghere- ‘intestine’ while ‘caudal’ is from the Latin cauda ‘tail’ – whose earlier forms seem less clear. But, in terms of differentiating the distinct parts of the CNS (central nervous system) of the *brain vs the spinal cord, the homophony of this being its caudal part is somewhat tantalising to me as an amateur linguist and natural philosopher – retired from a main career as a mind/body doctor.
