What does the root word plegia mean?

The root word plegia means paralysis or stroke. It comes from the Greek word πλῆξις (plēxis), meaning "stroke".

Plegia is often used in medical terms to describe conditions involving paralysis or loss of movement:

* Paraplegia: Paralysis of the lower half of the body.

* Quadriplegia: Paralysis of all four limbs.

* Hemiplegia: Paralysis of one side of the body.

So, the root word plegia essentially refers to a loss of movement or function.
