FAQ
Frequently Asked Questions
In standard English, 'dura' is almost exclusively used as a short form of 'dura mater' in medical contexts. It is not a standalone word in general vocabulary.
The dura mater is the tough, outermost meningeal layer, while the pia mater is the delicate, innermost layer that closely adheres to the surface of the brain and spinal cord.
No. While it shares a Latin root with 'durable', in modern English 'dura' does not function as an adjective meaning hard or tough. It is a specific anatomical noun.
Because 'dura' is a common Russian word meaning 'fool' (feminine). It is a classic false friend and using it in an English medical context could cause significant confusion or unintended offence.
