| The pia mater has received little attention regarding its function in the deformation of the spinal cord under compression. |
| The innermost layer is the pia mater, a delicate vascular layer adherent to the surface of the brain and spinal cord. |
| In the uppermost portion of this photograph, the pia mater has been removed to display the tracts of the posterior funiculi. |
| The cortical system of arterial branches ramifies over the cerebrum to supply the cortex with arterioles that anastomose in the pia mater. |
| Between the pia and arachnoid membranes is the subarachnoid space, in which the cerebrospinal fluid circulates. |
| The innermost meningeal layer, the pia mater, is closely applied to the surface of the brain tissue and carries many small arteries and veins. |
