The space ends distally at the lower border of the second sacral vertebra, where Since the arachnoid extends to the second sacral vertebra, but the spinal cord ends at the level of the upper lumbar vertebra, a large cistern, the lumbar cistern, is formed below the second lumbar vertebra. It communicates with the intracranial subarachnoid space via the foramen magnum and ends at the level of the S2 vertebra. Technique The subarachnoid space is the interval between the arachnoid membrane and the pia mater. Dictionary ! The cauda equina is a bundle of spinal nerves that arise from the distal end of the spinal cord. The spinal cord terminates at L1/2 in adults and L3 in infants. The spinal cord as well as the brain is covered by three layers which are called the dura, the arachnoid and the pia.Now between the arachnoid and the pia there is a space which is filled with fluid, this space is called subarachnoid space. C. Subarachnoid space. The epidural space contains adipose tissue, lymphatics and blood vessels. One distinct feature of the spinal subarachnoid space is the dorsal arachnoid septum, which extends from the dorsal midline outer membrane to the subjacent spinal cord along the middorsal vein (Nauta et al., 1983).

This space expands at the level of the conus medullaris of the spinal cord, forming the lumbar cistern. Cerebrospinal fluid-The clear, normally colorless fluid that fills the brain cavities (ventricles), the subarachnoid space around the brain, and the spinal cord and acts as a shock absorber.

The subarachnoid space between the arachnoid and pia accommodate about half the of the total volume of the CSF. D. T12 vertebra. In the subarachnoid space of the vertebral column, the fluid-filled space between the end of the spinal cord (vertebral level L1-L2 in adults) and the end of the arachnoid-dural membrane (vertebral level S2). A subarachnoid hemorrhage is bleeding from a damaged artery at the surface of the brain. 1 Within the brain, the CSF fills four hollow spaces designated the left and right lateral ventricles, the third ventricle, and the fourth ventricle.
