deepest layer of meningeal coverings of the brain, just superficial to the brain cortex/spinal cord and just deep to the arachnoid. reflects into all the sulci of the brain and is well vascularized. paper thin, aids in nourishing, cushioning, and protecting the CNS. gets inflamed during meningitis infection, with resulting CNS impairment.
The pia mater is extremely hard to pick away from the gross brain/spinal cord ... haha, now you're sharing in my pain of getting through medschool!

Pia
A Pia is a loyal, devoted friend, who can make you smile just by walking into a room. Pia's are lovable, cuddly, funny and adorable, and always make you feel that you are the most important person in the whole world. They are smarter than the average bear, but like to play the dumb blonde, just for giggles. They are frisky, playful and tough to the bone, NO ONE messes with a Pia unless she says so. But if you're trustworthy and loving, you are welcomed in her pack.
Who needs a partner, when you got a Pia?

Pia
Correct me if im wrong. x
Italian: devout
Norwiegian: Princess
Samoan: Beer
Maori (Native New Zealand): a species of fish (but not a cool fish like an angel fish) and also my favourite Maori meaning:
To shine. Like the deep shine of obsidian or the deep shine of the ocean.
My name is Pia. I was not happy about this for my school years but it has grown on me and has some amazing meanings that i hope other Pia's will enjoy too!
