Pia Matter
* Thin, innermost mennix composed of collagen and elastic fibers.
*vascularized
*cerebrospinal fluis (CSF) is found in the subarachnoid space between the pia matter and arachnoid
The thin like membrane that covers the brain is "Dura Matter", and the thin like protection surrounding the spinal cord is a "mylein Sheath".
The innermost membrane covering the brain and spinal cord is called the pia mater. It is a delicate and thin layer that closely adheres to the surface of the brain and spinal cord, providing support and protection. The pia mater is part of the three meninges, which also include the dura mater and arachnoid mater.
Pia is an abbrev. for pia mater, which is the innermost of the three meninges covering the brain and spinal cord
pia mater is the innermost layer.pia ma·ter (mtr, mätr)n.The fine vascular membrane that closely envelops the brain and spinal cord under the arachnoid and the dura mater.( dura mater is the OUTERMOST layer. )
The outside of the spinal cord is protected by three layers of membranes called meninges: the dura mater (outermost), arachnoid mater (middle), and pia mater (innermost). Between the arachnoid and pia mater is the subarachnoid space, which contains cerebrospinal fluid that cushions the spinal cord. Additionally, the spinal cord is encased within the vertebral column, comprised of individual vertebrae that provide structural support and protection.
When the spinal canal fails to close completely around the spinal cord, spina bifida occurs. Spina bifida is a congenital birth defect.
Tethered Spinal Cord is a condition where the spinal cord is attached to the spinal column and that causes the cord to become stretched.
the arachnoid layer is located between the dura and pia matter in the skull and around the spinal cord. further: these three layers make up the meninges, a system of membranes that surround and help protect the CNS (central nervous system) along with the help of the cerebral spinal fluid. dura is the outermost layer and pia is the innermost layer; arachnoid falls in between these two.
The three membranes covering the spinal cord are the dura mater, arachnoid mater, and pia mater. The dura mater is the outermost, tough layer that provides protection. The arachnoid mater is the middle, web-like layer that contains cerebrospinal fluid, which cushions the spinal cord. The pia mater is the innermost, delicate layer that closely adheres to the surface of the spinal cord and contains blood vessels.

the spinal cord is used to send messages around the body from the brain ie use left hand and arm to wave etc...
The pia mater is the delicate innermost layer of the meninges-the membranes surrounding the brain and spinal cord. It is delicate and vascular, and follows every contour of the brain.
