Pia mater/Related Articles
From Citizendium, the Citizens' Compendium
Pia mater: The innermost of the meninges; surrounds the entire brain and spinal cord, descends into sulci.

- Nervous system : The control unit of bodily functions in animals.
- Central nervous system : The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
- Brain : The core unit of a central nervous system.
- Brain anatomy : The study of the brain's structures.
- Brain development : The build-up of the brain from ectodermal cells to a complex structure of neurons, glia and blood vessels.
- Brain mapping : The projection of brain properties onto a standard coordinate system.
- Brain morphometry : The quantitative study of structures in the brain, their differences between individuals, correlations with brain function, and changes of these characteristics over time.
- Brain segmentation : In brain morphometry, the decomposition of an image of the brain into different classes of tissue, e.g. white matter, grey matter or cerebrospinal fluid.
- Brain size : Umbrella term for various measures of how big a brain is.
- Brain ventricle : A space in the brain that is filled with cerebrospinal fluid.
- Cerebral cortex : External tissue layer within the vertebrate brain, ensheathed by the pia mater; home to the nerve cell bodies; important in learning and dementia.
- Cerebrospinal fluid : The liquid in which the central nervous system is embedded.
- Gyrification : The folding process during brain development, or the extent of folding.
- Human spine : The part of the human body which is composed of the nerves of the spinal cord and its protective covering; the vertebral column or backbone.
- Pial surface : A surface representing the boundary between grey matter and cerebrospinal fluid, as reconstructed from neuroimaging data; roughly corresponds to the position of the pia mater.
