Pia mater (/ ˈ p aɪ. ə ˈ m eɪ t ər / or / ˈ p iː ə ˈ m ɑː t ər /), [1] often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. Pia mater is medieval Latin meaning "tender mother". [1] The other two meningeal membranes are the dura mater and the ...
Leptomeningeal collaterals lie within the leptomeninges, the two deep layers of the meninges called the pia mater and the arachnoid mater. [4] Their diameter has been measured at approximately 300 micrometers, [ 5 ] but there is variability between individuals in the size, quantity and location of these vessels, and between either hemisphere ...

In anatomy, the meninges (/ m ə ˈ n ɪ n dʒ iː z /; [1] [2] sg. meninx / ˈ m iː n ɪ ŋ k s, ˈ m ɛ n ɪ ŋ k s /; [3] from Ancient Greek μῆνιγξ (mêninx) 'membrane') [4] are the three membranes that envelop the brain and spinal cord. In mammals, the meninges are the dura mater, the arachnoid mater, and the pia mater.

The tela choroidea is a very thin part of the loose connective tissue of pia mater overlying and closely adhering to the ependyma. [ 2 ] [ 1 ] It has a rich blood supply. The ependyma and vascular pia mater – the tela choroidea, form regions of minute projections known as a choroid plexus that projects into each ventricle.
The occipital bone is at the back of the skull. The dorsal cavity is lined by the three meninges. The three meninges are the three membranes that envelop the brain and spinal cord, in which the central nervous system developed, which are the pia mater, the arachnoid mater, and the dura mater.
All three meninges of the cortex (dura mater, arachnoid mater, pia mater) fold and descend deep down into the longitudinal fissure, physically separating the two hemispheres. Falx cerebri is the name given to the dura mater in-between the two hemispheres, whose significance arises from the fact that it is the outermost layer of the meninges ...
