Did you know the brain and spinal cord are wrapped in three protective layers of tissue, collectively called the meninges? The term **dural** specifically refers to the dura mater, the outermost, thickest, and most durable of these membranes, which acts as a crucial shield for your central nervous system.

In medicine, the brain is enveloped by a triple-layered membrane called the meninges, with the outermost layer forming significant partitions. So, what is a falx in medical terms? A falx is a sickle-shaped fold of dura mater, providing crucial structural support and separation for the brain's hemispheres.

The dura mater is a thick, protective membrane encasing the central nervous system, and in a medical context, it's what dural is primarily known for. However, the term's meaning can change dramatically depending on the subject, referring to an alloy, a place, or even a video game character.

A fascinating fact about medical etymology is that the term 'arach' is derived from the Greek word for spider, *arachne*. Understanding this root helps clarify what does arach mean in medical terms.
