The pia mater has 21 pairs of denticulate ligaments which attach it to the arachnoid and dura maters. Named for their tooth like appearance, the denticulate ligaments are traditionally believed to provide stability for the spinal cord against motion within the vertebral column. Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ... Elseviers logo Elsevier, the worlds largest publisher of medical and scientific literature, forms part of the Reed Elsevier group. ... The pia mater (Latin: tender mother, itself a translation from Arabic) is the delicate innermost layer of the meninges - the membranes surrounding the brain and spinal cord. ... A ligament is a short band of tough fibrous connective tissue composed mainly of long, stringy collagen fibres. ... The Arachnoid mater is one of the three layers of the meninges, interposed between the dura mater and the pia mater and separated from the pia mater by the subarachnoid space. ... The dura mater (from the Latin hard mother), or pachymeninx, is the tough and inflexible outermost of the three layers of the meninges surrounding the brain. ... The Spinal cord nested in the vertebral column. ...
